"And this heat makes me worry that the manufacturer claim might be incorrect."

The have found some way to dissipate heat, they wont' tell me yet how they are doing it.
:-( The are playing with some mufti-array 5 W units and tell me the heat is not an issue.
The smaller W LED's are not that big an issue.. My friends was 720 W using 600 LED @ 1.2 W
ea.. If you look at the Solaris it has 50 arrays and each array has maybe 10 LED or so
(guessing). PFO lighting is a pretty big company.

collecting

guy to

Those Cree are pretty nice and go up to 3 W. That is a nice find Pszemol :-) I have only
see Luxeon. I'll have to drop this on my flashlight guy

: 47 lumens per watt, 57 lumens typical output

Well one thing you can count on is watts being practically
the same as measuring heat. How many watts it uses is how
much heat it will generate. Now keep in mind that's not
necessarily how hot the bulb will be, but how much total
heat will be created. This includes the amount of heat
that is created in the tank as the light energy is
absorbed. Naturally you want as much of that wattage going
into the visible light leaving the bulb, and less of that
wattage being produced into direct heat leaving the bulb.
Keep in mind too, that a soldering iron, is only 3 watts.

A heat sink will easily take the heat away, and spread it
out so that it is not all concentrated in one location.
