Can you insulate above an LED downlight?

This information should be in the documentation that came with your light but...

Since most of the energy used in an LED is given out as light (as opposed to an incandescent bulb, which uses most of it's energy as heat) it is probably OK to insulate above it. However the transformer pack may still get hot during operation, so for a particular fitting you are better off to check the manufacturers specification before taking any chances
