I figured i can get away with a computer heatsink for one of these, but I'm less sure about oh, let's say four. While yes, i have quite possibly gone mad, halogen bulbs of comparable light output are nearly the same price. While the halogens only need a passive heatsink, they are prone to self destruct if fingerprints / the wrong dust particle gets on it at all.
Now, back to the chips, how should i go about cooling them. I figure that four computer heatsinks in close proximity might be pushing it, do i dare go for a waterblock style?
The aim is to keep it as cheap as possible. This is for an auditorium in a public high school. We scrounged together $1000 (CAD, f u exchange rates!) from a provincial drama festival, and want to make the most of it. (Most of this is going towards buying moving head fixtures.)
How should i go about this? I want these chips to last a very long time.
Slight complication, the fixture could be placed in a hot location.
