Yes, this is a proven technique, and relatively easy. Simply dislodge your remote ballast from the wall during the light period and place it with both hands into a bucket of water. slosh it around a bit to make sure the water is nice and liquidy. You should be stone cold within about 45 minutes, depending on the temperature of the room. Sorry, I just couldnt help it. actually, i saw some liquid cooled ballasts but they were quite pricey.:thumbsup:
