Ordered these “Mini touch lights” from BG since I have over 50pcs of unused CR123 with expiration date in 2017.
They are fairly lightweight and well made. Can fit a CR123, 16340 and even 18350 (very snug fit). There is a very sensitive contact area that can be activated with anything that is even a bit conductive.
I didn’t expect them to be very bright since the spec says 100mA with a 16340. But they are actually very dim, I think about 10-15 lumens max. I have one CW and one Warm, the tint is pretty decent and the beam spreads out nicely. They could work well as little night reading lights or for camping.
Unlike the USB powered SMD light, these are not as bright and remain cool during operation. A typical USB SMD light draws over 200mA and gets hot quickly.
Warm (1 feet)
Cool (1 feet)
Took some readings:
-OFF standby draw: 2.5uA
-CR123 3V: 28mA, ~4 Lux 1M
–18350 4.2V: 50mA ~6Lux 1M
According to these numbers, a fresh CR123 can run for about 40 hours. (1,400mAh typical)
