Hi JJ
I would like to help you out here...
but it would help if I knew more about your cage.
Cage size.
age of Cham.
How heavily planted is the cage (ie. is there much shade?)
Yes,
while it is true screening does reduce UV as somebody mentioned,
it would have to be pretty dense screen to knock it down by 50%.
Average UV reduction we usually see with screen is 25 - 38%.
If you have a baby cham and / or it is in a small cage,
a 10% or 12% bulb -
especially if it is a t5 High Out-put, would be allot of UV and could harm it if you have not enough shade. (or sparse plants.)
Just as a VERY general rule of thumb...
The length of the bulb can be 2/3 - to the full length of the cage.
If it is a small cage , say less than 2 feet tall and less than around 16 inches wide...
Then stick with a 6% bulb.
Why? .. because the cage is not large enough to create the proper UV gradient zones.
And if you have a baby, also just do the 6% bulb for now.
If it is a well planted 24 x 24 x 36 or 48 tall cage and has ample plants for shade then yes, a 10% or even better, Arcadia t5 12% bulb would be ok.
If you can afford a Solarmeter, they are a GREAT INVESTMENT.
And they always hold their value for resale.
I can give you more specific advice if I know the size of the cage and type of Cham.. or even better if I can see a picture of your set up.
Because then I would know exactly what you have to work with.
But I hope this info helps.
Also, this is a great video to see how UV is emitted from bulbs and it is only 4 min. long. At the end it shows a 10 - 12% t5 bulbs out-put....
So you can see what I mean when I say it would be too much on a small cage.
