[QUOTE="Tortoise Tom, post: 136550, member: 27883"] I prefer flood bulbs over spots. Spots concentrate too much heat in one spot. Remember, the point of the heat lamp is to simulate the warming rays of the sun in our indoor enclosures. The sun warms a very large area. :) There are many strategies to get the correct temp. You can have a higher wattage bulb and a lower basking platform, or you can have a lower wattage bulb and a higher basking platform, like your retes stack. In a tortoise enclosure, I raise or lower the bulb and fixture instead of the basking platform. In a screen topped lizard or snake enclosure, I raise or lower the basking platform since the bulb and fixture are at a fixed height. In a closed chamber, I either experiment with different wattage bulbs, or simply run the bulb through a rheostat to get the basking temp correct under it. I usually start with a 65 watt flood from the hardware store. HD sells a 6 pack or 12 pack of 65 watt Sylvania floods pretty cheap. I like to have extras on hand. They always seem to burn out 1 minute after the stores close just before a holiday. I buy bulk packs and then defiantly give the finger to Mr. Murphy! What ever lighting and heating you use, the important thing is to check and re-check the temps at lizard height. I use both a digital thermometer like this one: [URL]https://www.lowes.com/pd/AcuRite-Digital-Indoor-Black-Thermometer/50425254[/URL] Just lay it where the lizard would bask and see what it does after an hour of baking under the heat lamp.

I've never used or seen the need for a retes stack, but I also don't see the harm in using them either. And I also debate whether 130 degrees is really necessary.
