    vho bulb placement

    I had an electrician wire my lighting system and when i installed my canopy, i noticed that one of my 48in bulbs are running along my rubber holders (so my glass can fold) connected to my glass. The rubber glass holders are about 2 cm thick. I am using URI bulbs with internal reflectors. Am i at a disadvantage and should i move the bulb 2-4 cm away from the rubber glass holders to maximise the light? Also i noticed that the bulbs seem a bit dirty inside and one of them has a couple of spots. Is this normal since they are new?

    Hi,
    2 cm will not bother it, although it would be better if it was moved.Are you seting up a reef?if so really no need for the glass top since salt and minerals will continuasly get it dirty cutting down your light intensity.

    For the particles in the bulbs, many times some debris may be left inside does not affect the performance of the bulb.
