Yes is was an HTG supply bulb. spectrum enhanced(more blue), 10% brither (55,000 lumen). Yes knowm it was clean, i think that maybe a few drops of water hit it, and i didnt notice anything by the time i left the room. Picking a bulb up tonight, thankfully they only had to suffer 1 day on about 500 lumens per sqf
oh yes, and the bulb was horizontal, i mean not a perfectly straight line, but as close as possible
