No. But the inside of your canopy should be white. The reflectors for the lights are on the lights, like you said. Do you have the three piece end caps? If you do, make them slightly tight, meaning the length of the bulbs are 24". So the span between the end caps should be 23 and 3/4". You'll see what I mean. They are "spring loaded" sort of. So tighter is better. HTH--Bob
