Any take on lights with fans vs. fan-less? Reliability concerns? Noise concerns?

It really Depends on the light. My experience with fans, noise/reliability are: You Get What You Pay for!
We have had a couple of different lights that we brought in for customers that where spec'd for them. (DFC) The cheaper units had loud fans in them. Some of the really cheap ones didn't last too long when they had power 24/7.
That Said, Some that were spec'd were very impressive and are still running strong.
As far as Mega, they are great very quiet and very reliable.
