First impression after opening the shipping carton: A cute little tin can! After opening this box: The lamp looks even smaller out than expected, it really is by far the smallest AAA lamp I've ever had in his hands. Screwing, into the battery, screw, turn: OK, Firefly is very dark, but in a room stockfinsterem it is enough actually for orientation. LOW OK HIGH was not quite the revelation: The difference to 25lm lamp of a well-known competitor was not as great as for declared 120lm expected another 60lm lamp seemed even brighter (the lamps were held so that the spots on a white wall were the same size). With other battery there was a little lighter, but still not what I expected. So the lamp head attached to a DC power supply. OK, those were now well 120lm, only no NiMH battery has this tension and not a normal AAA primary cell provides so much power without too much break into the voltage. What has since used as a power source link for the reference tests? Well, based on fresh batteries, it is then but the brightest AAA lamp that I've been using. Only in the color grading of the LED I can not follow the manufacturers. Compared with my anderern neutral white lamps this is really quite yellowish! This is much more warm than cool white, possibly the wrong LED has since installed?
OK, apart from the really far too yellow my feeling color matching the lamp is all in all, OK, pretty small and it quite bright, even though it may yet have no 120lm. Therefore, I draw from all in all only one star.
Addendum: At least the darkest and the brightest mode does not seem to be (good) stabilized, you can pretty well recognize the status of the battery. In brightest mode which is understandable, in the darkest but not which is then but to still be able to start something so quickly too dark.
