A powersum will not do it, if you are choosing the 2 in 1 route like me, use a megaray.ok im getting ready to move my panther chameleon to a 48"/24" enclosure. for the basking bulb i am wanting to use the zoomed powersun 100watt. should i use any other uvb bulb?
These numbers seem pretty weak, maybe your fixture is somewhat damaged.A powersum will not do it, if you are choosing the 2 in 1 route like me, use a megaray.
I have tested with my lights (both 100w) with a UVB meter and a infra red heat gun at 12 inches away from main basking spot.
The Power sun measured at 35uw while the megaray mesured at 45uw
Thats not that bad for the powersun, where it lacks is how much heat it puts off.
The powersun measured in 73.4 F compared to 89 F for the megaray, this temperature was taken in the hottest spot.
So for you to get the heat you need from your powersun you will need to lower it too close and will send dangerous levels of UVB to your reptile.
Now these are MY LIGHTS, I dont know how consistent the readings would be from one batch to another. If you choose to go that way, BUY A METER and you will be fine and save a few bucks with time cause you can use the lights until they are really finished.
