Tiny USB lights

There are a few tiny / cheap USB lights out there that would work well with a powerbank (or flashlight-powerbank).
There are several main types of these lights available:
1. The most basic, some LEDs and one or more resistor:

2. With a driver enabling regulated brigthness:

Example review: https://www.youtube.com/watch?v=s7oLob-ewrA
3. With colour temperature regulation:

Can anyone share their experiences with those?

2. They are very nice when used as hall lights when connected to a USB power supply. At minimum brightness, they’re about as low as moonlight, and therfore, can be used as emergency lighting with a powerbank.

They are cheap enough on eBay from international sellers that you could try a couple and not worry if they don’t satisfy you. Prices start at 75 cents including shipping for the ones at the top with three LEDs ( )

one shown at top – 3 LED $.75 https://www.ebay.com/itm/Mini-Portable-USB-Power-3-SMD-LED-Night-Light-1W-Camping-Lamp-Torch-White-2PC-CA/183358197784?hash=item2ab1001018:g:~-gAAOSwFnFV8Ots:rk:11:pf:0&LH_BIN=1

Yeah i have some of those earlier ones. (2014 iirc)
Touch sensor ramping.
The first ones had audible PWM, which is quite annoying.
They “solved” it by lowering the PWM frequency… Yes, really…
I also have 2 with light sensor, they turn on when dark.
Adjustable sensitivity. Not the best circuit design though, but they work.

There is also another type – with another USB port, so you can stack them several in a row :

I have a few of those. I got some that has ramping and a few with sensor to turn on in the dark. Darn thing so small; forgot where I put them. I remember bringing one when I went traveling oversea.

I got five of the Soshine 6 LED variable lights in cool white four years back. They work very well and I keep them taped to my power bank and the one I left for my GF.

They work well enough and were less than $2 ea., shipped.

I have this light on the keys for several years. It works reliably. I gave some of them as a small gift.

Here is what I did with one of mine :

EDIT : If you’re afraid of tearing the LEDs on your key-chain, here is a solution :
UV glue

 I have several (warm withe) of the simple kind and love them too.

Whenever i offer a small powertank i add one and usually keep one taped to my own powerbank.

 

The cheapest i have found are from ebay at 0.99$ for 5pcs but not tested yet as they are still somewhere between china and europe Wink

 

Btw -X3- i don't see any picture in your post while it sounds like there should be one, could you please provide a link ?

They seem more popular than I expected. Smile
Thanks for all the comments. I ordered 2 kinds already and I intend to get another 2 on 11.11. Smile

Has anyone swapped LEDs in their lights?

Neat idea, X3!!
These are small enough to keep at every location you might be at. Always waiting for the lights to go out….

Yeah, teeny ones in CW and WW(!), bigger ones with integrated touch-switch (on/off, ramping), and don’t forget the “toothbrush” lights, usually COB but sometimes discrete, that also come in handy.

I kinda stocked up on a lifetime’s worth when GB was blitzing these things at wonderfully low prices (now, forget it, 10× as much).

Especially the WW ones make great nightlights, ‘though the pwm can be horrible. Just scan the room with your eyes and you’ll see a big connect-the-dots trail.

Still, I carry 2 of ‘em in the little pouch-thing in which I keep my earplugs and flash-thingy.

I love how for some sellers the touch control thing  translates to an amazing :

"Using the latest fingerprint technology, it will be able to use your fingers to achieve control of LED lights"

 

Wow ! Fingerprint technology ! Wink

 

@ -X3- : Ok i got the pictures , Privacy Badger doesn't like googleusercontent.com very much ! Could you please provide a link to the glue you use ?

Once it’s cured with UV, you should have a sticky but shiny surface…
The problem is that the sticky finish will collect fingerprint, pocket lints etc…
So you have to polish it, on a denim jean for example…

I guess the sticky surface is no good for output…

Indeed, sticky finish is what i get too.
Clean and polish then.
You did a nice job at that. Thumbs Up

I’ve got this type of a light today. White.
It’s a bit larger than I expected really.
Has no UI, plug in to turn on. Beam is mostly rectangular, not clean. Very cool ugly tint. I don’t like it.

It would be cool to have a micro-USB sized light…Type-A light + micro USB adapter = not so tiny….
I did a quick search, failed to find anything.

I wonder if it would be easy to use oshpark or similar service to make a simple light with Optisolis and resistor…

I’ve got my second set.
Warm variant of these:

Beam is artifact-free. Tint is OK. I like….but they were too large.
So I decided that I wanted to be like CRX, took a file and worked on it until I liked the result (checking if it’s still working from time to time).
At one plug-in, there was a blink and the light went dark.
No good.

So I took another, filed a little less. It works and is significantly better than stock. And it weighs 13% less too! That’s a whooping 0.4g saving.

In my powerbank:

I intend to use it as an alternative to diffuser that weighs less and produces warmer light. Smile
Will it work well? I’ll see. Smile

I have a couple of those that I justed used with my power banks during a 3 day snow storm power outage. They were easily as useful as my fancy expensive lights!
