    Light Shootout Cost Per Lux

    Light Shootout Cost Per Lux-lights.jpg

    Just did a quick spreadsheet for the light shootout. I removed some of the lower Lux lights.

    Light, Cost, Lumens, Measured Lux, Cost Per Lux

    I like it. Thank you for doing it. I have about 10 new lights to add and I'll publish this kind of data with a graph.

    I have both a Piko and a Magicshine.
    The Magicshine is way brighter than the Piko despite the lower lux rating.
    How am I misunderstanding the "lux" definition?

    I like the Piko's build quality, but I had assumed I would get more oomph.

    I have compared both the MS and Piko side by side as well and had the opposite conclusion.The Piko was considerably brighter than my MS on full power.Maybe i have a bad MS,or you a bad Piko.Were both lights cool when making your comparison as the Piko will power down quite quickly?.

    I have not actually used any of the lights I just took the data from the MTBR test and added the cost per column to try and give people a way to show a per Lux value for the lighting.

    This has a decent explanation of lux and lumens.

    http://www.brillianz.co.uk/data/documents/Lumen.pdf

    The way I think of it: lumens is total light output. lux is light output per area. given the same led, a light with a spot reflector will produce a higher lux reading than the same led with a flood reflector.

    I find lux ratings to be less meaningful to me than measured lumens. the problem is that accurate lumen measurement is expensive while lux measurement is cheap enough that I can do it....

    edit: I should add that having both measured lumens and measure lux is ideal, giving and idea of overall brightness and spot intensity.

    Does that include the retest of the Strykr Pro?
