Follow-up to my question:

I realize that a halogen flood lamp would produce heat, but no UVB. So, if I use one of these heat producing bulbs on one end of the enclosure and the 160 watt mega ray heat/UVB producing bulb at the other end, what are the recommendations in terms of wattage for the halogen flood lamp? Do they produce the same amount of heat watt-for-watt as the mega rays (i.e. does a 160 watt halogen flood lamp produce the same amount of heat as does a 160 watt mega ray UVB lamp)?
