I’m going to believe is just trolling until I see actual pictures. BTW, have any of you seen what happens when a drop of cold water hits a HPS bulb that’s been running all day? It’s not fun to be around when that glass shrapnel goes flying.

Have you heard a plant fry when they touch the bulb it’s literally “sizzzzzzzzzleee”

I’ve also had that happen to my head, scar to prove it lol

all I wanted to know is will this damage the bulb, or is it lowering the light output, the bulb has no direct contact with the cradle, the reflector wing is being cooled.

Any HID with an arc tube inside has an optimal performance temperature. Generally with SE HPS lamps the jacket design on the lamp offers a layer of insulation as there is a vacuum in there and the arc tube inside of that is insulated pretty good. On DE HPS lamps you don't want to blow your fans on the lamp because it cools the arc tube and reduces efficiency / output.

To answer your question, a cool arc tube (the smaller tube inside the lamp where the light is generated) is definitely going to limit output, possibly shorten lamp life as well due to the less stable arc.

Just cause they designed and engineered it that way doesn’t mean you have to do it. It’s been 6 weeks man.

don’t forget to add it’s kind of a safety thing.
