im about to order a retro for my 55 that is 48inches long is it better to order the 46.5 inch bulbs that will fit with endcaps inside the canopy or go with 48inch bulbs that with endcaps is 48 5/8 and make the canopy alittle wider. also i havent made my canopy as of yet. do i need any spacing behind the light reflctor and the top of the canopy?
