Two Reptisun Fluorecent bulbs...

[vince66mphs]

Okay, so I'm thinking ahead and might be about to spend a rediculous amount of money for Sigrun's "adult" enclosure and I ran across this really cool looking EcoZone vivarium controller (http://ecozonevivarium.com/products-vivarium-controllers.aspx.

They sell dimmable fluorecent fixures to go with it, but they're all dual light fixtures. Can a Beardie actually get too much UVB if I put two Reptisuns in there?

Any thoughts on using two Reptisun 10 bulbs?

Anyone?

Beuller? Beuller? :lol:

You don't have to use two Reptisuns. Instead, use a single Reptisun, then a standard fluorescent tube in the other fixture (daylight variety, 5000k-6500K). This will give you the UVB of the reptisun + additional ambient light which is good for their vision and coloration.
To answer you question, yes it is possible to overdose them on UVB. However you won't likely do it with two Reptisuns, assuming you can keep the beardy at least 10" away from the bulbs. If you use a reflector, then you'll probably want to keep them at least 14"-16" away.

Note, the bulbs in that test are reptisun 5.0 tubes. 10.0 tubes have a significantly higher UVB output...hence why I adjusted the recommended distances to about double what you'll see on that graph. If you don't have the bulbs in tandem like in that test, and instead just use two shorter bulbs to simulate a longer bulb in the viv, then treat the whole setup like a single bulb. Its only when you place them next to each other that the UVB output compounds.

Also, as noted in that test, dual bulbs = lots of light and glare. Make sure to keep the light source directly overhead.

Thank you VERY much for the information! Looks like I'll go with one ReptiSun and one standard.
