The light will be upright in the enclosure facing front to back on the inside of the door, Yes High Output.. I'll be using it for the plants mostly. Is this a good idea?? Here is a picture of the enclosure I built to give you an idea where they will be placed, inside along sides of door in a grooved area designed for these bulbs with screen over them.. I run 2 power sun 100watt full spec. metal valid bulbs in the canopy for Scratchy the past 2 years..
