Low Profile LED Downlights

You can easily work out the heat, as the switched mode power supplies used as drivers for LEDs are very efficient, never worse than about 85% and often over 90%.

 

So, if you had an LED rated at 10 W, then the driver unit will dissipate around 1.5 W or so, not enough to worry about in the overall scheme of things - it will barely feel warm to the touch.

 

I used over-sized switched mode power supplies for our LEDs, and even the largest of these barely feels warmer than ambient temperature after the light have been on for an hour or so.
