Yitee 5pcs LED Circuit Boards USB Light Keychain Super Bright 6 LEDs Mini USB Light Lamp with Smart Touch Electrodeless Dimming Switch for Laptop Keyboard Light(Pure White), Qty:5

Excellent for use around the house. They can be set extremely dim, making them a perfect night light in the restroom. Or they can be used for reading with a gooseneck USB arm mounted on the wall. They're also good to take camping because you can plug them into a power bank and get very good area lighting. The touch response is excellent. They do get a bit hot on high mode so just know that.

These USB LED sticks are a really cool idea.Uses I've Found:- fun to play with- throw one (or multiple) in a USB battery and you have a light brighter than most flashlights- put one in an old < 1A an cell phone USB brick (you know you've got a couple of these lying around) for a slim, cheap night light- when added to the end of a USB extension cable, it makes pretty cool under-cabinet lighting- plug into you laptop's USB port for some extra desk lightingUsage (since never defined well in the product description):1. Tap the back and it turns the LEDs on and off. The LEDs will "fade in" to the set brightness when turned on and "fade out" when turned off.2. When the back is long pressed, it dims or brightens the LEDs. Long press once and it brightens. Long press a second time and it dims (... and so on).For the record, I purchased these myself from Amazon, and was *NOT* provided them in return for a review.

Its bright and adjustable

I purchased these since I do a lot of computer repair work & I needed something cheap that could give me a lot of light. Also, I love that you can insert them facing up or down. and they have adjustable touch controlled brightness. 5 of these for the price offered is pretty good.These 6 little white LEDs are bright! But I have discovered a few problems along the way.1: They get REAL HOT! But because the back is where the touch sensitive part is (Yitee logo), you cannot mount a heat sink on them.2: They cannot be used as a keychain because the hole is too small and the delicate circuits are exposed. Best you can do is use a Lanyard & carry it around your neck.Other thoughts:Would be nice if there was a jumper or solder point to disable the touch sensitive part, and have the LEDs turn on to full when power is applied, making them suitable for use in LED projects. Still, I am quite happy using these to light up the inside of a case, or to stick them in a portable USB battery & use them as a bright flashlight. I would definitely buy again.

I received my Yitee USB LED lights this evening and WOW THESE lights are super bright. I tried to take some pictures of the light when it was on full brightness but the light is so bright you may not see the whole thing. I also included the light on a dimmable setting. If you want a light inside your truck so you can see or beside your bed for a night light so you can just touch the back part of it to turn on then these are definitely the ones you want to but. I give them 5/5 ⭐️⭐️⭐️⭐️⭐️ They should last a very long time but time will only tell!!!!

These lights are simply amazing. Ideal for camping, power outages and to light a meal that you must photograph and post on Facebook.On high they draw 230mAh of current at 5 volts. So with a 5000mAh battery the run time on high will be at least 19 hours.I've recently made Frankenlight - Night Trekker Edition. Twin 6 LED Yitee Cool White lights powered by an Anker 5000 mAh battery. As configured it attaches firmly to my backpack waist belt or shoulder strap. 180 Lumens with a light beam angle of 160° make it a unique light source for night trekking. It's shown with the optional omnidirectional lantern head.Yitee 5pcs USB Light Keychain Super Bright 6 LEDs Mini USB Light Lamp with Smart Touch Electrodeless Dimming Switch For Laptop Keyboard Light(Pure White), Qty:5

I'm using these for accent lighting around my L-Shaped desk and so far I'm very pleased with the functionality and the light output of these little devices. All of my power strips and desktop power hub has high output USB ports that supports the proper amperage for these interesting little devices. Note: Lights will flicker if USB ports are lower than 2 Amps. Turning on these light requires just a tap and to use the dimmer function requires you to just lightly hold your finger down on the smooth side and release when you have reached the desired light output. After powering these off, the brightness level will remain the same when you turn them back on.

Works as a USB Light but there are a few flaws. The light would flicker at medium brightness in the beginning but would start flickering at any brightness level after ten minutes of it being on. Another flaw is that the unit would get really hot to the touch if you left it on for a while. Mines started getting hot to the touch when using it at ~60% brightness for 20 minutes, luckily you do not have to touch it that long to shut it off and let it cool down. This is not good for people who want to use this as a night light or plan on using the light for more than 30 minutes. This USB light is bright but it comes at the cost of the PC board heating up quicker than it can handle in terms of heat dissipation. Another flaw is that the PC board is exposed so you have to be careful with how you handle it, but it is nice to be able to see the circuitry. The last flaw is a minor one and that is that it can only be face up or down, depending on how your power source is configured. All in all, it is OK as a light, but only for short term unless you want to risk it overheating.
