Re: Fenix LD02 vs Fenix E12 - measured and commented
Are these comparisons between LD02 and E12?
Yes. Point was to show the differnece between Lumens and Lux since as a rule people say they want more Lumens and mean they want more Lux (throw). Too often, people want light that throws to the Moon. They do not consider that means a very narrow beam which is absolutelly not usefull at 0,5-2-5-10 meters away (too strong and too small a hotspot). Why are we not using laser pointers as lights? They do throw faaaaar
Pic with 2 beams shows Fenix LD02 8 Lumens @ 21 Lux low beam, while the far stronger right beam is Fenix E12 which on Low places 82 Lux at the same wall. What we can not see here, is the large spill of LD02 where remaining Lumens are distributed.
As for 3 beams shot: left is Fenix E12 Low 8 Lumens @ 81 lux, the middle is the Nitecore Sens AA 6 Lumens @ 48 Lux and at the right is the LD02 Low 8 Lumens @ 21 Lux. It is much more illustrative to convert Lux to FL-1 meters: E12 8 Lumens 18m - Nitecore Sens AA 6 Lumen 14m - Fenix LD02 8 Lumen 9m. Cut the meters to half go get more realistic 1 lux meters (instead of standard 0,25 lux).
For a comparison: Fenix TK61 at 8 Lumens would produce about 1360 Lux (throw 74 meters!) - none of the above lamps can throw at all to 74 meters with their 100+ Lumens! So, 8 Lumens, or any other number of lumens is regularily used absolutelly wrong.
With 1 Lumens, these 3 lights would produce: LD02 = 5 Lux = 4 meters throw, E12 = 15 Lux = 8 m throw and TK61 = 170 Lux = 26 m throw. So, who needs a 1 Lumen lamp? You mean throw 4 m or trow 8 m or throw 26 m?
