Thanks for the responses, I'm not familiar with lighting and am trying to pick up a thing or two. What is the external ballast that you're talking about? So you could see the heat of an HID as a plus in cold weather and the lack of heat in an LED as a plus in warmer weather.
I guess vision x has switched their high end lights to internal ballasts and STARTERS, so not too much of a concern anymore.
When I drawing the new light set up, I saw that people in colder climates were having trouble with light cannons getting buried in snow because the LED lights wouldn't get warm enough to melt it off of them. I don't care about running my lights in the snow so I didn't care about that con.
