I recently noticed that my fluorescent fixture does not have a reflector on the back of it. I tried looking around to find one but I cannot find any add on reflective backings. Is it really necessary that I get one? I have a 36 inch t8 fixture. If you can guide me to any websites that have add on backings for sale, I'd appreciate it.
You don't HAVE to have one, but they do concentrate the UV a bit by redirecting
the light that would be going away from the cage back in the right direction.
They are made by/sold for Arcadia but they will obviously work with ReptiSuns too (they are just
held on with plastic clips). I like them, but again it's not required as long as the bulb is close enough.
