This bulb was donated by Rob Talkington. Rob also donated a Capture the Sun 160 watt flood bulb.

Note: Just like the T-Rex Active UVHeat bulb, this bulb also has "UVB hot spots" where the UVB is at its greatest intensity. The center of the bulb doesn't seem to be the spot where the intensity is the greatest, although it is relatively high. For example, if I move the UVB meter just an inch or so from the center of the bulb the UVB readings jump all over the place. So, I think that the easiest way to measure the intensity is to measure from the center of the bulb. This bulb was brand new on October 10, 2003.
