Very bright, very cool! UPDATE!

UPDATE AT BOTTOM!

I just received this light and so far, 5 stars. It is VERY bright for a USB light. Every bit as bright as a bare 40 watt bulb. One light is enough to light up our 15'x10' dining room. I've had it plugged into my 10,000mah battery for two hours so we'll see how long it lasts. After two hours of being on, it's not very warm, cool enough to touch and carry around.

Update- I liked the first one so well I got another one. I ran them together off my 10,000mah battery pack and they ran for over 5 hours! Together they easily put off enough light for entire room to read books, play games, cards whatever. Perfect for camping or power outages the attached photo is of our 10'x12' canopy lit by only these two bulbs.

They both arrived on time and in good condition. Reading the reviews I was still unclear ...

I recently purchased 2 of these "Daisy-Chainable" USB / LED lights along with an "EC Technology 3.Gen 16000 3 USB ports". battery/charger unit. I purchased the more expensive "Daisy-Chainable" version simply for the convenience of being able to extend the "reach" of the lights. They both arrived on time and in good condition. Reading the reviews I was still unclear how long I could expect to have usable light from a battery. Many reviews stated they got blah blah hours of light from their battery packs without specifics (i.e. how much light before the battery exhausted itself, the battery specifics, were they run until the battery was depleted, etc). I decided to test it (with this particular battery, purported 16,000 mAh).

The bulbs arrived in good, working order. But they arrived without any instruction "manual". Not that a manual is particularly needed. Plug the lights into a USB power source, turn them on. But I was kind of hoping for some tech specs (i.e. power draw) so that one could at least do some "in theory" calculations as to how long they may last with a particular mAh battery. But alas, nothing like that came with the lights. They came packaged in small cardboard boxes with nothing else. And I didn't find any of that type info on the bulb itself (only marked "Camplight". The back of the switch seemed to indicate it should be plugged into a 2A USB power source. That at least would seem to indicate I could theoretically expect 8 hours of light from a 16,000 mAh battery.

When "Daisy Chained" both lights worked as expected. However you should be aware that the far light(s) are dependent on the switched light closer to the power source. In other words the bulb/switch closer to or attached to the power source must be "on" for the subsequent bulb(s) in the "daisy chain" to operate. You can't have the farther bulb "on" with the closer (to the battery) bulb switch in the "off" position.

I charged the battery to capacity. It sat for a couple days then I decided to see exactly how long it might run one bulb. I was fairly certain I could expect 8 - 12 hours.

At approx. 0700, before leaving for work I plugged in a single bulb to the 2.1A port on the battery and hung it over the granite counter in the kitchen. When I returned from work at approx. 1900, it was still going strong and the battery was still showing 3 of the 4 indicator lights. Pretty cool.

I felt confident enough to let it continue overnight. So I left it on and went to bed. I woke up around 0400 and it was as though I'd left a kitchen light on. Still putting out the same amount of light and the battery was showing only 1 indicator (of 4). I let it run until 0500 before turning it off. I knew each of the 4 battery "indicators" (theoretically) represented blocks of 25% of the battery's capacity. I didn't know if I was seeing the end of that last 25% or the upper range of it. Not wanting to completely exhaust the battery and perhaps damaging it, I opted to turn the light/bulb off.

So that was about 22 hours of light from one bulb plugged into a 16000 mAh battery. More than I expected from a bulb which seemed to indicate it wanted to be plugged into a 2A port of a battery.

I bought the light for camping and power outages. That battery / 1 bulb combination would easily get you through a night of constant use which under most circumstances would be over-kill. Camping doesn't seem to need constant overnight illumination. Nor would a power outage. In a catastrophic situation you may need constant light but hopefully we'll not need to experience that. But this combination of 1 bulb / battery will produce nearly 24 hours of light in a very minimal package. Maybe you find yourself doing surgery in a 3rd world country, this might get you through the night. In that case I'd opt for the "white" light. That would produce a more stark, blue/white light. I purchased the warm lights and they are very similar to the incandescent light a normal lightbulb produces. It produces way more light than a "nightlight" though certainly not the amount of light a 60 or 100 watt bulb produces. Probably very similar, like advertised, to a 40 watt bulb.

I read in one of the reviews that plugging 2 bulbs into a USB power source did not seem to use twice the "juice" of a single bulb. The reviewer seemed to think it was closer to 2 bulbs using the only the power necessary for one bulb. That doesn't seem realistic but I may retest using both bulbs with the battery fully recharged. But it that case I will wait until I can actually be around to monitor the battery. I will update this if I opt to do that.

Bottom line: These bulbs and similar battery/charger units produce way more continuous light, in a broad pattern, than any flashlight I own. A flashlight may be brighter and throw light farther but generally in a narrow pattern where light is only useful in that beam. These ("warm") bulbs produce a very useful "area of light", similar to a conventional 40 watt bulb, and with a similar battery power pack they produce many, many hours of useable illumination. The 7' cord really allows you versatility in the placement of the light. As another reviewer noted, the bulb is lightweight and the cord weight (though itself negligible) can still tilt the bulb when hanging and perhaps one would find exact positioning of the light a bit challenging. Judging from my limited experience I highly recommend these (for camping, power outages, portable outside lighting etc). If you can justify the extra cost I'd also recommend the "Daisy Chainable" version simply for the added versatility. But in truth, with the amount of light these produce, you may not need that versatility and you may want to use the savings on a reliable power supply/battery.

Bright , easy to use, low power and fantastic for emergency power loss or daily accent lightning
by Compton B (5 out of 5 stars)

Not a paid review or something like that, just bought this for my personal use.

This is a really cool light. I love the color and the brightness. It wouldn't replace a bulb to light an entire bedroom for daily use but it can provide significantly more light than any usb powered device I've seen thus far. I'm currently using it plugged into my router's usb port and have it running around 12 hours a day for the past month or two. I use it to light the stairway into the basement since it's very dark here even during day light hours. It's more than enough light and I imagine in an emergency power loss situation you'd feel very comfortable using this to light a room or table for several hours, I've tested this scenario a little using a portable usb battery pack and I'd estimate it used under 1000 mah per hour ie: a 10000 MAH battery should give you up to around 10 hours use.

I also really like the easy to use hook built in on the bulb with a small loop and slightly larger loop, I'm just hanging it off a nail.

This light will probably be too bright to be used as a night light but I would absolutely recommend it instead of leaving a regular light on at night.

There are two versions of the bulb, and I purchased the one that is warm light, the warm light looks a lot like a regular old light bulb that is closer to the color of sun light, where as the other color is a bright white which I would only recommend for use in a storage shed or closet because it's even brighter but typically cool white is not as nice to look at as warm white.

I would also recommend this as a nice computer desk light that could be plugged into the computer or laptop's power supply.

My photo's show one with no lights on and one with only the SunJack light bulb. My phone camera is very sensitive to dark lightning so, the dark picture will appear to have more a little more light than is normally visible.

Daisy chain no longer supported
by J. Allred (2 out of 5 stars)
April 8, 2018

I ordered 2 of these specifically because they claim that they can daisy chain - but neither of the lights I received have a USB daisy chain port.

Having used the lights over the weekend (camping), I'd be inclined to give the lights a 5 star review (assuming they hold up).

However, I don't appreciate the false advertising. If they can't daisy chain then don't advertise them as such - hence the 2 star review.

I am sure someone is going to jump in and say that I must have ordered the wrong item. As I look through the questions and comments I see that they used to have 4 or 5 options on the listing. However, as of right now there are only two options - Warm White and Multi Color (I ordered the Warm White).

Search for "daisy chain usb light" on Amazon and this is the #1 item in the search results (that's how I found it). Then open the item link and look at the page. Because there are currently only 2 options, and because both descriptions talk about daisy chaining, and because many of the comments talk about daisy chaining, it is not clear at all that the ones currently being sold are not daisy chain-able. It wasn't until I received the items, went back to the listing to verify that they were supposed to be daisy chaining, and then read/skimmed many of the comments and questions that I realized that they must have had additional options in the past (which were removed).

I know that part of the issue is how Amazon supports multiple items on the same page (which don't always change the description). Yes, the description does say "Now Comes in Five Options", but how was I supposed to know (without reading through all of the comments and questions) that the page in question used to list all 5 of those options. From where I sat, this was the page that hosted two of the daisy chain options because that is what many of the comments and questions mentioned.

In my opinion the seller should have updated the description and removed the information about daisy chaining when they stopped selling those options. If I have the light selected that doesn't support daisy chaining, then the description should either say nothing about daisy chaining, or state explicitly that daisy chaining isn't supported on the option I chose.

Am I going to return these? No, it isn't worth the hassle (although, I can only use 1 in my current

LOVE IT, Use it to light up the wall behind your computer.
by Son of a Cactus (5 out of 5 stars)

I think I reviewed this already. I Paid Full Price and bought this USB plug color changing camp light for the back of my desktop iMac, fits in the round hole in the iMac's stand base. Lights up my med Gray wall behind screen perfectly to avoid eye strain, the white is enough brightness and the colors are beautiful and it all plugs into my USB port on back. This avoided my having to buy those sticky 3M Tape led strips that are sold to attach to the backside of PC's. No messy sticky strips stuck to my iMac, this light was a much better choice. I don't think it would be bright enough to light up a wall behind a large screen TV but would be ok for a smaller Smart TV with a USB port, or just buy a phone charger plug and plug it into that. I've had this lighted now for about 10 days going 24/7. it never gets hot and is doing a brilliant job for me. At night I switch the light to Red for good sleeping. Was very happy to find this, had been wary of messing up the back of my PC with those sticky strip lights. This is the only light of it's kind that I could find and I shopped really hard looking for something just like this, on Amazon and other sites online. Highly recommend.

Excellent Emergency/Camping Light for Hanging Up
by TGP (5 out of 5 stars)
September 16, 2018

I ordered several of these lights for emergency/camping use. I am well pleased with my purchase.

The lights are just as advertised. They are quite bright; it's uncomfortable to look at, even with household lights on. They are omnidirectional, with the exception of the area which mimics the socket on a conventional incandescent or twisty florescent bulb. Because of this, they're best suited for area lights. You could, in an emergency, walk with one, but you'd have to either hold it over your head, or somehow shield your eyes from the light. That's really not what they're designed for. They have no power supply, so they must be plugged in to something supplying power to a USB A female plug. The light has a USB A male plug on the cord.

Although they look like a conventional incandescent home bulb, they are only about half that size.

They have a long power cord (I'm estimating 6 ft.) with a rocker switch for power. Build is adequate, but not what I'd call robust. They have a plastic hanger to suspend the light in a tent, fold out canopy, or anywhere you can reach. Since they're LED, they can also be simply laid down wherever convenient, without worry of heat damage. I would never plan on laying it on a table where I was eating, for example, because it's so bright, it would hurt your eyes.

For my purpose, primarily camping, this is an excellent little light.

Awesome little light!
by Jennifer Fawcett (5 out of 5 stars)

I can't give this product enough thumbs up. I am an avid camper and have used Mini lights from battery-powered LEDs to Luci lights. This little light is far more versatile than a Luci light and doesn't weigh much more. You can charge it up on a USB or you can use a solar panel and it will charge all day. An added benefit is that the silicone part of the light will glow in the dark for a couple of hours after you turn the lamp off. I have hung it in my RV and in the tent and I have flipped it over and used it as a table lamp . It will illuminate table more than adequately to eat dinner or play cards. Not bad for a little light that packs up smaller than a hockey puck. Highly recommended.

A sphere of light instead of a beam. LOVE!
by Emma Dickinson (5 out of 5 stars)

Zomg, where has this thing been all my life? I love products that solve problems, which is exactly what this little light bulb has done for me. I recently started doing outdoor craft fairs and lighting the booth from dusk until the end of the event is a real problem. Generators are noisy and stinky, and prohibited from many events for that exact reasons. Traditional batteries are only strong enough to power a light for a couple of hours. And I have zero interest in creating a fire hazard (and potentially electrocuting myself) by using a deep cycle marine battery. Enter the SunJack CampLight. What impresses me the most about this bulb is that it casts light in a way similar to incandescent bulbs. The problem I've encountered with every other LED is that the light is so directional that it's only useful as a spotlight for a product. This bulb provides a 5' sphere of light. I can read a book if I'm within 3' of the bulb. I purchased six bulbs and three 20800mAh dual-output battery packs. They provide enough light inside a 10'x10' tent for customers to comfortably view my products. One battery pack can power two bulbs for more hours than I've bothered to determine. Based on general recollection of usage, I would estimate a conservative minimum of 10-12 hours. I typically use them for 5-6 hours at a time and the battery still displays four lights indicating 75-100% charge when I'm finished for the night. So in case you're wondering how long a USB battery pack can power this little bulb for, the answer is a really long time. I can't stress enough how useful these are for vendor booths at outdoor events. All of my lighting and power fits into a small box the size of a ream of paper. Love this light bulb.

Specs:

The cord is 7' long, which is critical for my purposes because it allows me to place the bulb almost anywhere in the tent and position the battery pack where it's out of sight. The power switch is about 5.5' away from the bulb and there's about 15" between the switch and the USB plug. The "white" bulb is a bright, true daylight white. It's not blue-tinted, but has a hint of a cool/grey cast (as opposed to warm/yellow). It works on both USB 5V 1A and 5V 2.1A outputs. The bulb is very lightweight and appears to be well-made. The bulb warms a little bit after an hour or so, but it's still cool enough to comfortably wrap your hand around.

Love. Love. Love. Thank you for making this product.

Good for geeky camper with USB power pack or 12-volt portable marine deep cycle battery.

INITIAL REVIEW DATE: 11/4/2014

Nearly perfect. I was looking for something to use as nice tent light and this worked. I have a portable deep cycle marine battery in a battery box. The box has two 12 volt DC outlets. I throw a 4 USB outlet plug into an outlet and can then route these USB bulbs anywhere. We put one inside the tent and one outside the door.

I took a hard look at Goal Zero's 24001 Light-A-Life LED Lamp as well. They are slightly different given the plug and voltage differences. I do prefer the look of Goal Zero bulb/lamp. I'd probably choose it if they were price the same or close. But this SunJack USB Bulb is nearly 1/4 the price.

Pros
- One bulb is bright enough for a large 8-man tent.
- Light color is bright white. I normally prefer warming white lighting. However, the light is definitely white with no blue (super cold white).
- The form mixed with the low power drain make this near perfect.
- My light came with a USB cable that has an inline power switch. I had no idea. Pretty nice if you can position the switch in a convenient spot.

Cons
- Not quite as stylish as the competition. However, the competition is also 3 to 4 times as much
- Wish the bulb had ability to daisy chain more bulbs. I realize it would force the bulb to be a bit larger.
- I would like to see the price come back down. I'm guessing these took off and the seller quickly realized there was a lot of headroom when compared to the nearest competitor. As mentioned, the Goal Zero 24001 really isn't a direct comparison either.

I really have no real gripes even at the fifteen price. I've used two for 6 nights of camping as of 11/12/2014

REVIEW UPDATE
9/5/2015
============================

Light still works great.

Today, 9/5/2015, I picked up the "Daisy-Chain Warm White". Testing at home, this offers the light color spectrum that I prefer. Much warmer than the original product. They sell the "colder" light as well and I assume it is the same color spectrum as I initially bought.

I'm going camping soon and will test. If I like the warm light, I may have to replace the older/colder lights.

One interesting note. I recently got a DROK Mini USB voltage meter (on Amazon) and found something interesting about how the lights work daisy chained. When 2 are daisy chained, they use the same amps/watts as a single bulb. Each light is dimmer. Possibly out of ignorance, I was expecting them to pull 2x amps/watts. Now, I assume running 2 lights, daisy chained, will use the same battery power as just one.

I could see this being a bit of a deal breaker for some. Others, may not care. I'll test, but it seems like giving each light you want to run its own battery pack would make sense if brightness was the key. Otherwise, daisy chaining 2 or 3 together may be your optimal use with one battery and needing to maximize usage time.

I'm also ditching the "marine deep cycle battery" for an Anker Astro E7 26,800mAh. The marine battery was suppose to give me about 100,000mAh. For my purpose, trading portability for weight is ideal. We'll see. I may switch back or use both.

Absolutely worth the price
by Private Citizen (5 out of 5 stars)
October 1, 2017

I have 3 of these. I ordered the first one a very long time ago.

I was concerned about two things - power consumption and longevity of the bulb - and was pleasantly surprised about both.

As a test, I plugged my first one in to an AC -> USB converter in my bathroom and just left it on full time. That was over two years ago and it has not failed. Longevity issue answered.

For a second test, I used a small phone charger solar-panel type battery pack with a USB port to see how long it would last before draining the battery. 72 hours of continuous light on a charger that would only charge my phone twice. After that, I recharged the battery pack, plugged in this bulb, and hung it over the solar panel on the charger. Apparently, the light frequency is very compatible with the charger because I got 96 hours of light. Power consumption is excellent in my opinion.

I cannot really speak to this products ability to stand up to rough handling as mine have never been subjected to that, but I will tell you that my (now) third device has a permanent place in my bug out bag along with a fully charged solar battery pack.

Hope this helps if you're on the fence about the product...

This light has a niche where it is useful, but there are better USB lights out there.
by FixerDelta (3 out of 5 stars)
January 4, 2019

The main reason I bought this product was because I was interested in the daisy chain feature and wanted to compare it to my other USB lights. I got 3 since that is what the manufacturer says is the most you can connect in a row. The place this light pulls its weight is when either you have very limited number of USB ports available or need to reach long distances from your USB port. With each bulb you add to the daisy chain, they all get dimmer. So, when you add a second the first dims and the second is not as bright as the first. Add a third one and one and two both dim, with the first being the brightest and the third the dimmest. When I plugged a fourth light in from a different manufacturer, all three of these dimmed and the fourth didn't light. So I agree with only a max of three of these in a row. When all three are lit, you can extend a dim light over a decent sized area and have enough light for movement and minor tasks. While I didn't test the lumen output, I believe the advertised 340 lumens is combined between all the lights plugged together. Using two of my other USB lights I get a better lit area for less cost but slightly higher amp draw. From my tests, the most efficient use of this USB light is to plug it into a 2.1 amp or higher USB port and then plug one of my other USB lights (made by Onite) into this one. This is the lowest quality construction and the highest cost per bulb of any USB light I have purchased. I do recommend taking a drop of hot glue and using it where the cord comes out of the base because it is quite loose and could easily break the solder points.
