Wanting to make this drop in 100% duty

[trip]

Spent a couple days on here reading through tons of threads, lots of great info on all types of projects. I have a project that I am working on. Wanting to use 8 of these http://www.dealextreme.com/details.dx/sku.11836
and 4 of these per unit.
http://www.dealextreme.com/details.dx/sku.32953

I have available 12-3vdc endless constant power and can adjust to any of these to support a larger driver if need be but would like to keep each driver separate if at all possible to make this look clean.

Have tested a couple of these running 3.2v. The led itself is getting warm over time, don't think it's too hot but wanting to make sure they last. What is a high temp on one of these led's? Rated for 50,000 hours but would like 100,000 hours life if possible. Does anyone know of another led that is around these specs Size/lumens that can be used in this manner that is 100,000 hours life? If not I can use these until 100,000 are made/found
From what I have found out they are using


320 lumens at 50,000 hours of led life
225 lumens at 50,000 hours of led life

Here are the led's used and the specs cree gives
www.cree.com.
At present we mostly use XR-E series, XP-E series and XP-G series.



Will post up pictures and videos when this is all working the way we are hoping.. Have done a first run at this but wanting to put some better led's inside to give it some more output. These fit and look great. Any help/info would be great.
Thanks. :twothumbs

Those drop ins do not supply adequate heatsinking for long term usage at full current. They are designed to make contact with a P60 style flashlight host, and make thermal contact with the body, dissipating heat.

So if I swap the driver out to this one

Still going to need some kind of heat sink to keep everything cool if I am running this for 5-10 hours at a time?

Is there an alternative led/driver/ Cylinder type heatsink (maybe one of these)http://www.candlepowerforums.com/vb/showthread.php?t=198785
or all in one combo that we could use with an R2,R5 led with a similar setup as a drop in?

This is what we had as our first version. 12v 1watt 260lumens with a 15 degree reflector lens. Have had this for over 2 years with no problems. From what I have read the R2,R5 are better led's, this is why I am wanting to use these but can't get them to stay cool.. Guess I can lathe out some aluminum cylinders to see how they hold up to the heat?

Is that a motorcycle?

You need a thermal pathway that is sufficient to transfer heat from the LED's and drivers to an external area with lots of surface area. I mean lots.

In an enclosure like that, their is no real way to do that...

Yes, we have already installed this previous version and have been running it for over 2 years. Will get this figured out and post up or findings.
