There is a sizing chart but here is the run down for you. 10watt->1500, 20Watt>3000, 30watt for 3000. I have a twenty watt and love it. If you live in the south and have a tin roof I would go up one size. FYI-Make sure you have adequate make up air. That means enough outside air will be able to circulate through your venting and not draw air from your house. Look and see if you have soffit vents under your roof eves. Hoped that helped.

It depends on the bulb. I have large spotlight type lights and used the 410W. 310W would be for a smaller bulb.

It's probably close to 24" wide by 18" tall oval shape. Look at any roof that has satellite antenna and you should be able to see the size.

Get on the roof with a long string. Place the string where you are going to run your heat. This takes some time but will save you lots of time later. Rember to add for you gutters and dawn spouts. Add all your totals and give it ten extra feet. Take your time and good luck. This stuff works great if installed correctly.

I used a standard incandescent 60 watt but you should be able to go higher if you want

There is no strict way of determining this. Typical installation varies but consider that you need to make a "zig-zag" pattern going across the bottom of your roof with the pattern being 2 to 3 feet high. Take some rope or string and duplicate this pattern on the ground to get an idea of how much works best. You certainly won't run the 240' of heat tape in a straight line so don't even consider that. We didn't do our entire roof , just two areas where we had problems. And it has worked fine with the automatic temperature and moisture sensors. We also ran some through the gutters which we were having trouble freezing solid as well. There is no strict way of determining this.

The base of the unit is 20 3/8" by 19 3/8". The template has you cut a 11" by 11" opening in your roof. This is for the bottom opening of the Light/vent. Your shigles cover the rest of the base. Is has worked very well & it lets in an adequate amount of light; especially for the cost. I bought 2 units. I installed one and am keeping the other as a spare.

This units holds 22" 24 watt tubes. if you have a 30" aquarium use a hood which houses 30" tubes ( little bit extending outside the tank) other wise there will be darker areas in your tank if you use a 30" housing holding 22" tubes.

Go to your local hardware and grab a 20lb tank the size you would put on a Outside Cooking grill. sometimes you can find them at yard sales or second-hand shops for cheap. We use a 20 pounder "Outside Grill Size" works great.

I'd get the 36" fixture then buy a bigger tank. ;)But to answer your question, the 10 inch fixture unless you want some overhang.

Yes we size to any roof. To speed order process I need to know if you have a hard or soft top. If it is a hardtop, I need you to take 1 measurement so we get your height correct and ship your windshield. On the roll bar, down by the body there is a weld that goes all the way around roll bar. It's above the 2 bolts. Start at that point and follow the roll bar up to the bottom lip of hardtop and send me that measurement. I will take care of the rest. We need windshield to clear hardtop, so it can tilt up and down.Thanks,Bryan
