Inexpensive LUX meter from China to measure your bike lamp's output. Stumbled across this while I was looking for something else. No recommendation, but I remembered you guys were discussing lux ratings not too long ago.

All a lux number tells you is how bright the light is at that given point and distance. Without a distance, and an overall beam field measurement and various points in teh besm spread, its meaningless.
