    SingleTri-star mounted to PC heatsink with auxillary optics:

    I need to let it run for an extended period to be sure, but this size heatsink may be overkill

    "Buckpack" driver module:

    No heatsinking required for it

    Single 4000k/85CRI tristar w/ aux optics on left, 15w (60w equiv) 6500k CFL w/ reflector assembly on right.

    The image does not accurately convey the true intensity of the Luxeon Rebel Tristar

    Well the heatsink is not overkill

    Wowza those look bright! So who's the lucky guinea pig? Will you be able to mount more than one per heatsink or is the heat output too great?

    I dont think I would put more then one to a heatsink. After about an hour run time the heatsink is nice and warm to the touch but not hot. Maximum operating temp is 135C so there is no danger of thermal runaway with this combination.

    Im not sure yet, maybe a H. pulchella division since I have a spare and already know what they look like under my T5

    Bright is an understatement Yann, its not anything you can look at directly!

    Hmmm. based on preliminary findings. Any idea what it would take to make a 4 foot light array? I am assuming power consumption is a bit less than power compact lighting (and probably less heat) and way less heat output than metal halide. Side project for Av8tor1 another garage start up company. Lighting CPs one person at a time :P

    Well I have no idea of how many tristars it would take yet. But based on one ever six inches, that would mean 8 of them, then 2 tristars per buckpack driver means 4 drivers, then 8 aux optics, 8 heatsinks... dc power supply, thermal glue... misc hardware and control housing

    ummmm guessing $300-400ish with zero profit margin LOL

    Some savings could be had by rolling your own drivers... but the additional investment in labor and the hassle would eat up most of the savings.

    Cheap enough for a DIY maybe but otherwise still too expensive... but man what a light, there would be nothing like it

    cold fusion for CP's LOL

    DIY Kits? Sort of like the AHsupply people and their compact fluorescent fixtures?
