But, i read a review of that light too in light reviews and Mev is reading 15000 lux. That difference is rather high considering that in many other flashlights both are getting almost the same lux readings. So, is there any case your Tiablo to be defective or the other supercharged?Seems to strange to me, something is going wrong.. :thinking:
That difference may not be as great as it seems. For this review, my lux measures were taken at 5m and calculated back to 1m (to allow space for the beams to converge), which may be giving a slightly lower calculated lux at 1m.
But I am also waiting at least 2 mins on the ACE-G runs to allow the light to come to steady-state regulated value (I've just revised my review text to make that point clearer). Initial output on a fully charged 18650 was well over 13K lux on my light meter, decaying to under 8K lux after 2 mins.
In addition to testing methods, when you factor in individual differences of emitters, reflectors, light-meters, etc., it is quite possible to see significant variation from one review to the next. Based on the overall output and runtime, I think my sample ACE-G is performing within expected parameters.
EDIT: P.S.: also keep in mind that lux is a non-linear scale in relation to output. To compare two lights, you should look at the square-root of lux (i.e. "throw") to account for the inverse-square decay over distance. In that sense, the drop I observed from 13K+ lux to under 8K lux over 2 mins is only a ~22% reduction in "throw". This is very consistent with the ~16% drop in output my lightbox is reporting over this time.
The results speak for themselves - nearly a 50% increase in output with no change (or an improvement!) in runtime.
