Are you using silicon/glue to stick the K2 to the Aluminium plate? wouldn't the heat melted the silicon/glue?

btw, I have some doubt and hopefully you can advice me before I jump into DIY my LED lighting.

Questions are as below;

1.What's the best distance/gap between each of the K2?
2.Why do you need 5W K2? 3W not enstuff?
2.How many K2 can one driver connected (in series)?
3.Are you using 24Vdc,1A power supply for K2? or higher voltage?
4.Do you use fan to reduce the heat?
5.Where do you get the Aluminium sheet from? Is it Ex?

Regards.
James

1.Depends on the heat sink thickness, typically min distance should be 1" apart.

2.I happened to find a batch of cheaper 5W thats why bought some to try.

2.Depends on the forward voltage of the LED. You add up all the forward voltage and it shall not exceed the max rating of the driver and power supply.

3.I'm using various power supplies from 30V to 24VDC, ranging from 5A to 3A.

4.No fan in used.

5.Aluminium sheet can be found in most aluminium hardware stores, mine cost about $70.

Look into the CREE LEDs, now they have a higher power efficiency than lumileds.
