There's a letter code in the model designation of most lamps, Philips products included. Printed on the lamp;@ttystikk
Question for you since you're Mr. Phillips. On the 315 LEC bulbs I know there's two different K temps, but the question I have is, are there two different bulbs specifically for vertical and horizontal orientation in the fixture? Or does it not matter? Am I confusing the 315 bulb with the Blue MH from hortilux that is like that?
H for horizontal mounting only
V for vertical mounting only
U for universal, or anything goes.
My old 860W CFM lamps were V.
My 315W CMH lamps were marked U.
Check yours, I'll bet they're U code as well.
My bill is in the mail...
