Thanks, Jake! It certainly is, and it's a lot lower maintenance, as well (ahhh...
Good question. The light went off some ten minutes ago for the night, and I just got up to touch it to see for you. The bulb and fixture are cool to the touch. Tomorrow when it's running I'll do the same. I will say, though, that when I'm doing trims, if my arm makes contact with the fixture for even about a minute, it's not painful or a bother, just warm. So I would say that it has no significant impact on the temperature of the tank (not that it could get much warmer here for December, 76*F!).
And finally, I never really congratulated you on your new administrative duties, so congratulations!
