Heating 101

[suzuki4life]

so what is the "par" rating?

I use GE halogen 50w par38 floodlight units....

they give an intense hot spot but won't heat a 4x2....not in my house one won't. Cold side is 68 degrees with light on for hours.

With 11" flexwatt under slate set at 85 degrees and I use a external ballast mbv for basking (produces 104 degrees surface temp)

keep in mind only 3/4 of the enclosure has flexwatt so 3 sq feet + of slate is cooler than the rest which stays a constant 82 degrees year round.

cool slate measures 73 degrees to give an idea how much temp can be lost in a sq foot.

ambient ranges from high 90's to 79 degrees 12 hrs daylight and 82 to 74 night.

I just looked up the par rating which makes even less sense....


a par 38 is a bigger bulb than a par 30

It's not always the size that matters...lol

I know the 38 is bigger but it does not emit as much heat as the 30 does. I do not the exact science behind it but it has to do with the shape of the bulb and it's reflector.

where do you get these 30's at?

I got these from walmart....

Always willing to try something new.

I typically get them from Home depot or menards. Just make sure you get the floods and not the spots

Cool I am eager to see your results! So far, everybody that I have pointed in this direction have all tried and it been quite successful with it. I personally just had to use the same set up temporarily in my 4x2x2 enclosure during the megaray issues.

if it works it will be a huge money saver on my monitor cage.
