Buckpuck with seoul led

[clifbar]

I want to make a new light with seoul p4 leds. I currently have 2 copper pipe end cap lights each with a k2 and a 1000ma buckpuck. Can I just take the buckpuck out and use it with the seoul p4?
Thanks in advance and sorry for the dumb newbie question.

Yes U can.

The base of the P4 should remain neutral.

Ok another dumb newbie question. If I want to have the led in contact via thermal grease, with the aluminum body of the light for heatsinking, do I have to do anything to keep it neutral?

 

[Szemhazai]

If led is connected via wires almost nothing - only remember to check conductivity after mounting socket in the case - sometimes negative is connected with case.

If you are talking about using a bare P4 emitter, the slug is connected to the anode, thus not electically neutral and must be isolated from the case. If it's on a MCPCB (star etc) it is probably isolated neutral. You might check to be sure.

How do you electrically isolate it and still have a good thermal connection to the body of the light? I don't want to use arctic alumina epoxy so I can upgrade the led if I want later

Honestly, AAA is the best way, but you will probably damage your old emitter removing it... I've knocked AAA'd stars off without damaging them.

If you are really interested in the later removal and upgrade of your LEDs, you should use a MCPCB (Metal Core Printed Circuit Board) mounted emitter, on a star for example. It is isolated electrically, and you can use small bolts to mount the stars with some thermal paste between the star and the heatsink area. Just make sure you use some small plastic or nylon washers under the head of the bolt so as not to make electrical contact with any of the connectors on the star.
