Smallest-Coin-holder

Connect to lights by twisting the red wire on this holder to all the red wires on your LEDs. Protect the connection with shrink tube.

Same with the black wire, connect it to the remaining black or green wires on your LEDs.

How many lights?

We tested 4 chip lights and found them to be nice and bright. More than 4 lights would not be as bright but you can do it! Mega won't be as bright on this battery.  This coin cell battery holder is for use with any of our 3 Volt LEDs

How long does the battery last?

4 lights lasted for 12 hours continuous light before the battery needed a change as the lights were not as bright. You could go longer depending on your preference for brightness.

How Long will it Last?
Fewer lights would be bright longer between changes.

"Can you mix sizes of lights, chip nano or pico?"

You can mix sizes yes. You can even run bulb or mega on this small coin cell holder.

"Can you mix colors?"

You can mix colors yes. You can't mix solid and flash though, the solids would flash along with the flashers. Solids would need a separate coin cell and holder.

"Can I run more than 4 lights?"

You can run more chip nano or pico than the suggested (4) it will not hurt anything. Just the LEDs will be a little less bright, and will need to change the battery a little more often.

If space is not an issue, our other 3 volt power sources can run many more lights: regular coin cell holder, AAA holder, AA holder, 3 volt wall adapter.

3 Volt Coin Cell Holder

The 3 volt coin cell holder for battery LED lights was easy to attach to my two miniature wall sconces, and the tiny on/off switch, which I attached to my miniature room's wall, added the perfect realistic, big room effect.

Perfect for the small portable projects

One of these was included in a kit project and worked so well to provide lighting for a small project. The switch is so small and easily hidden.

937 Battery Holder

The battery holder with the on/off switch works well. I wish that Evan Design offered a battery holder with an on/off switch that was part of the battery holder so the whole thing was more compact.

Thanks!

Thank you Roger for taking the time to leave us a review. We do not attach the switch to the battery holder because it requires the battery to be accessible so it cannot be hidden inside or underneath the project. But what you can do is take a toothpick and tightly wind the wire around the toothpick. Remove the toothpick and you have a nice neat spring with your excess wire. We hope this helps, and thank you again for your suggestion

3V battery snap holder with Switch

This is the perfect set up. Tuning two LED lights off one 3V battery neatly tucked in the back of my N scale Pullman car with the switch coming out the back door of the car for easy access. Works perfectly!!!
