temperatures are indeed the significnt goal, but a high wattage bulb (100 ) is seldom the answer...
better to choose the right kind of bulb. we use sylvania halogen floods, 90% are 45 watt, in a three bulb array (for a larger basking area) we may use two 45s and a single 90 watt. we have basking temps well over 160 at the hottest point (not forgetting to mention elevated basking spots : )
a couple of things- "reptile brand" bulbs are typically expensive(!), of questionable quality, and emit terrible heat. that is why folks need a 150 watt (or higher) reptile bulb to achieve a minimum basking spot of 120F. we get our basking temps with the 45 watt halogens, and even regular "lamp bulbs" in glass tank setups.
the economic savings over the long run can be immense, as the halogen bulbs are cheap, and incredibly durable. i have seen reptile bulbs pop, crack, burn out, and fall apart in a matter of days and weeks. we measure the lifespan of the halogen bulbs in months and years : )
45 watts is also a lot cheaper to run than 150 watts : )
and not least of all, the base of a 150 watt bulb runs AWFULLY hot, and can really be a danger to cheap or plastic fixtures, which are often found in reptile setups.
be sure to use FLOOD bulbs, not spot bulbs, and look for a brand with a consistently patterned face, for the broadest, most even throw of light and heat.
