50pcs Mini LED Lights with 25pcs Battery, Battery Powered Mini Electric Lights with Plastic Shell for DIY Crafts Paper Lanterns Dollhouse Accessory (Cold White)

So happy with these tiny lights! They just twist to turn on and off - just be careful to not fully unscrew them when you're turning them off. Super bright, which feels unnecessary for my use, but for other things would be great. They seem like good quality and I love that they have replaceable batteries versus being disposable. Great value for these - the price was way less than some I had in my cart (but hadn't clicked "buy" yet) on a different site. I'm going to use these for making miniature light fixtures. It will be so nice to not need to hide a cord/wire going to a battery somewhere else.

Make sure you read the description; 50 lights, each with their own batteries, plus 25 extra batteries as well. The tiny lights themselves are just simple plastic 2-part body with an LED plate and the batteries in the middle. Twist to turn them on and off - this is somewhat fidgety and sometimes requires a bit of back and forth - and you're good. I didn't run them for long enough to drain the batteries but after a good amount of time they were still shining and still at their apparent full brightness, and it's pretty darn bright as well. At their scale, they may as well be floodlights. I haven't earmarked a specific use for them yet, but I suspect they're going to be part of some robot models, or maybe dungeon architecture.

Works great for what I need
