Hi all CPF folks,
I want to know your comments about ANSI NEMA FL-1 which I personally find very defective, specifically runtimes. The problem is that this standard published in 2009 by companies like Petzl, Coleman, Energiner, Black Diamond.. doesnt differentiate between regulated and unregulated lights. Thanks to that, many manufacturers which mostly make unregulated (or pseudo-regulated) lamps have major advantage when publishing these runtimes, not telling customer that its slowly diminishing light (not constant). Sometimes published runtimes are very absurd, one example bellow with explanation why its not possible in the current world:
F**** HM65R (very common brand/model here)
claims 22h runtime with 400 lumens from one 18650 battery
If that would be constant, its impossible! For 400lm constant light you need at least 2W (very likely more than that), one best 18650 gives you 12Wh, that equals 6h runtime. And Im not taking into account any optic and electronic losses, in reality it would be much lower. But manufacturer claims 22h runtimes. Yes, they are not violating FL-1 but should at least tell the customer that light output is not constant.
Do you think its unfair to customers and should be changed? Would the information about light output regulation (unregualted, pseudo-regulated, regulated) be beneficial to you?
I need to give you also the background, why I am asking this question. Maybe some of you know that I started building my own powerful Lucifer headlamps 8 years ago, started then regular company here in Czech, currently 3 employees. We do all our headlamps fully regulated and tell exact runtimes, even though we could specify them longer (because of FL-1). But we do not exaggerate runtimes, its pointless to provide unreal data. Very often customers call me that this F**** or another brand claims much longer runtimes, is lighter and cheaper. I must tell them the whole story that they specify untrue runtimes, not telling whole story and after that they really suprised and wonder why its possible. Therefore I really think these companies are not telling the truth to the customers and thus violating at least EU customer rights.
Tell me in comments If you think the same or not?
