RE: [APD] LED lighting with Luxeons (preliminary results)

["Gomer Gomer" <iegomer at hotmail_com>]

They do get quite hot.  That is why I have that heatsink.  Given that I can 
hold the heatsink comfortably after the lights have been on for quite some 
time, it would seem to reach 40-50°C.  I can't even touch the PC bulbs 
without it burning (or atleast feel really really hot).  Considering the 
heatsink surface, I dont think these luxeons generate too much more heat (it 
that) then my PCs  I can try to monitor the temps to see the effect, but 
that isn;t top priority (to compare heat that detailed).

My LEDs are as far from the water as the PCs are (<2" for the nano and 3" 
for the larger tanks)
