Another quick question. I've been using the same Heat bulbs and UVB Flourescent lights for a while now (5-6months). When is a good time to get new ones? Or just use them until they burn out? Also, for Basilisk what's the best flourescent lighting? I've heard 2.0 and 5.0 and i've heard just 5.0. I have enough to have 2 flourescent bulbs, thanks.
