In theory thats right, in application, I learned from the 2g that it's not.
Mounting within acrylic (or in my case on the 2g within epoxy) the heat tends to be captured and retained. Results in a short lifespan. Yes the LEDs themselves are made of acrylic - but the amounts are minimal, surround several of them in a small area - and they do retain the heat a little too well.
My plan at the moment is to find a nice hunk of aluminum to drill, aluminum is very efficient at moving heat away - and transfering the heat - thus keeping the LEDs running cooler.
