Are you referring to the heat created..or just simply putting your hand on the case and judging that way.My hydrofarm xtrasun ballast run much cooler than my digital ones.
sealed electronic ballasts SEEM to run hotter as they use their casing as a heat sink to release their heat. They should be creating less heat in the room even while they feel hotter to the touch.

I've got 12 Lumatek 600w 240v units and cant say enough good things about them. Never gave me a problem..and the 240v units are tiny and barely even get warm to the touch.

For anyone interested in Lumateks..the dimmable units just hit the market with the ability to turn them up to 110% (super lumens they are calling it).
I'm not sure if they (lumatek) are making the right call here..just seems like a component prone to failure on an otherwise perfect ballast. The plus is that the newer lumateks are dual voltage whereas the older units are not.
THE BIG QUESTION in my mind is when is EYE Hortilux and other lamp manufacturers going to stop honoring a warranty on their bulbs due to hard use from electronic ballasts and now these new features to overdrive the bulb.
