Hi,
what everyone else said- the reptisuns are flourescent bulbs, while your zoomed light is incandescent (regular, normal screw-in lightbulb type). so basically, you will need two different types of fixtures, one incandescent fixture for your zoomed bulb, which gives off heat, and one flourescent fixture (long, tube ones) for your reptisun for the UVB since flourescnets do not give off heat.
I know reptisun actually makes compact flourescents now, which screw into an incandescent fixure. either way, you would still need two fixtures. UNLESS you went with a mercury vapor bulb, which gives off heat and UVB in one incandescent bulb. hope this helps!
