I have finally gotten around to comparing a few modded PM6 lights. They are the:
<ul type="square">[*]PM6/BB750/X3T (Luxeon V)
[*]PM6/1.6A/TWOK (Luxeon III) and
[*]PM6/1.1A/TWOK (Luxeon III)
[/list]
The first measurement was hotspot brightness, measure at 1 meter.
<ul type="square">[*]PM6/BB750/X3T: ~1800 lux
[*]PM6/1.6A/TWOK: ~2000 lux
[*]PM6/1.1A/TWOK: ~1600 lux
[/list]
The next comparison was a beam shot at ~15 feet to the top of the stairs. Oh, the only light on in the room is the TV and a 18watt flourescent about 25' away. The X3T illuminates the wall very well in this range. The TWOKs were also nice and white but boy, was the spot small!
--------------------------------------------------------------------------------
Next up was a trip outdoors. I took several shots of a nearby fence with the 3 lights and again, the spot sizes tell the story. Surprisingly though, the amount of light from the 1.1A TWOK and the 1.6A TWOK was not that different!
--------------------------------------------------------------------------------
The next series of shots are of the tree directly behind the fence. There is also a tree about 40' away behind the first tree. In real life, the 3 lights also illuminated the far tree but in different degree. The TWOKs did show up more tree but as expected, the spot was quite small.
CONCLUSION: Well.... I am still partial to the beam spread of the X3T (Luxeon Vs in general). At a distance of up to ~50-60 feet, I cannot fault it. The hotspot from the Luxeon IIIs however was a bit tight for me. It does throw it further but.... tooooo small /ubbthreads/images/graemlins/frown.gif If only Lumileds would release a Luxeon III based multi-die 10+ watt emitter /ubbthreads/images/graemlins/naughty.gif /ubbthreads/images/graemlins/naughty.gif /ubbthreads/images/graemlins/naughty.gif (You heard it here first /ubbthreads/images/graemlins/grin.gif)
