i;ve been confused on this for a while. i have a 36" wide terrarium, with 48" lights sitting on top of it. it would be really very nice if i could go out and get some 36" fixtures and put those over it, but 36" bulbs dont have as high of wattage.
does that mean less light? or does that mean that the smaller bulbs take less power to produce the same amount of light as the larger bulbs?
