...for me anyway. I put five fresh AA's and one dummy into the holder of THIS LIGHT (see 19th post down) which is a 5W SE mounted inside a M*glite 2D with 6AA battery holder to get 7.5V, and it metered 5,440 lux. I decided to put it up against the POOR MAN'S 9P running a SureFire P91 HOLA:
The PoorMan produced this reading from one meter away (multiply the reading by 10):
Then I stuck a sixth AA into the 5W Mag 2D and unleashed it on the poor meter:
The numbers speak for themselves (but I have to say it, 7,020 lux!), although there is nothing like the tried and true beamshot visual, so here they are from five feet away on a textured white wall:
The exaggerated coloring comes from backing off the camera to its lowest setting; actually the beams are both brighter with the U3U-binned 5W producing an almost perfect white color, with a tint just about matching the center of its hotspot above.
Then I angled both lights up against the ceiling from 25 feet away:
Notice how the center of the 5W M*g beam retains its brilliant, bright-white hotspot.
Of course I do not intend to keep driving it on 9V since the unusually low Vf of this particular 5W SE Luxeon makes it more than bright enough at 7.5V, but still it was a brief and interesting exercise in pushing the envelope. I think I may have to transfer it onto a smaller host, maybe even down at 6V, for a durable, pocketable, bright little EDC.
