So a few weeks ago I became frustrated with my standard 250 watt heat lamp, it is just too hot for use in SoCal. I found myself constantly switching bulbs and raising and lowering the light to get the temp just right. After reading a thread about another person searching for lower wattage heat lamps, and the suggestion that they look towards the reptile section of pet stores, I started doing a bit of research and found the holy grail of clamp lamps: Dimmable (temp adjusting, how cool is that!) Clamp Lamp: http://www.reptilesupply.com/product.php?products_id=1555 And paired it with this bulb... Nocturnal Red 150 watt Heat Bulb: http://www.reptilesupply.com/product.php?products_id=136 The combo works fantastic!!! I have the light set at a fixed height and all I have to do is adjust the built in dimmer switch to adjust the temp. The Nocturnal 150 watt heat bulb has created the best sleeping conditions so far at night. No chicks partying in the wee hours of the morning. They sleep through the night, I sleep soundly, and all is well. For those of you living in colder climate's they also make the same lamp in a slightly larger size (10") that accommodates a 200 watt bulb. Enjoy!
