I found these “new” lights today at a local Dollar store Chain here in Canada, (Dollarama) for $ 1.50 each.
This thing is miniscule, literally almost Nano-sized. it even makes a Fauxton look huge. for a buck fifty, they are well made. Smooth anodizing, anodized very smooth threads, O-ring, and a quick-release keychain clip. They use four LR41 cells, and a single 5mm white LED. They are available in Anodized Red, Blue, Black, and silver. They look much better and much more durable than the plastic fauxton lights.
it took a whole 3 minutes to do. I pushed out the LED head module with a pencil, then swapped the original blush-tint 5mm, LED with a higher CRI Warmer White 5mm LED. put it back together and as seen in the photo below its a nicer warmer tint. ( and actually became a bit brighter with the better warmer 5mm)
Below is this Nano-Light between the HUGE Thrunite Ti2 and Trustfire Mini-02:
the head could easily be turned down in a small lathe to make it narrower. The front is sort of shaped like a reflector now, if it was polished it may work as one.
You can sand the led flat and if you come close to the little cup where the light comes out you might even get some photon recycling from internal reflection, but my guess is that mainly you just widen the emission angle without increasing the die illuminance.
I tried this on one of the cheap DX 5mm keychain lights... Carefully sanded down to just above the cup, then polished smooth. It makes the light crazy-floody, which lessens its usefulness as there is so little light to work with in the first place.
Nice looking little light too! I've been looking for a Nano-clone for some time, this looks like it might be what I need! I'll start looking at the Dollar-type stores we have around here to see if I can find one.
