SSC P7 Super SPOT DIY - Help

Long time lurker, first time poster.
oo:

I'm trying to build an uber spot light based around..

and was wondering what people are using to drive these things? any simple diy circuit solutions, or am I stuck buying something like..

Do you think the 'heat sink base' will cut it for 6 hours of run or should I somehow rig this thing to a cpu heatsink..?

Help please!

Yup, that would need a bigger heat sink like a CPU type you mentioned. Every thing else seems good as long as you have the correct DC powersource..

I was just thinking about wiring in a wall wart type, or even spare PSU to the buck... say something like 6v.

You would be far better to use a 3D Mag with one of the custom made P7 heat sinks and this reflector http://www.dealextreme.com/details.dx/sku.12229
it will need to have some material removed from the top lip.

I don't think I see what you're saying norm.

Are you saying, us a 3d maglight as a fixed light?

I thought you were building a flashlight, not sure what you mean by fixed light.

The module you linked to has almost no heat sinking. Your title says super spot, that reflector is in between flood and spot, I have used the reflector I linked to in a few builds and I really like the beam but it isn't really a spot beam. Both reflectors are basically the same except the one you linked to includes the driver and the one I linked to is meant to sit hard against the black plastic surrounding the dome on the P7.
If you could explain exactly what you hope to build, I'm sure myself or others will be able to suggest some ideas.

Thanks norm. I guess I wasn't being clear enough.

I'm building a spotlight. Think of track lighting, but no track and just one unit. I figured fixed light meant... a light, fixed in place.

Like this except, not so fancy. It's going into an existing light fixture so it'll be hidden. The fixture is already actively cooled with 2 80mm fans.

The light would be hard wired into a constant power supply of somesort with the juice being supplied from the wall (120v 60Hz)

A Xitanium with a few P7 would work well.

Doesn't really make sense to install a power supply off your mains voltage, and than use another driver.

A CPU heatsink would work well with your fans. And keep the LED(s) cool.
