Check these bulbs out. Seem pretty cheap. Would be curious what they would read on a par meter. Kind of look interesting as a 600nm+ supplement for white LEDs as a red and IR boost.

this is the spectral distribution of these charts.

I would love to see the test but I fear you will have massively stretchy plants: there is sooooo much far red in that bulb. I Wouldn't let it run full day.

The problem is the wattage, with 150w it's going to be a lot of far red and ir in one place. I've been playing with an idea of something similar but smaller in scale; adding a few halogen spotlights and running them on a dimmer. They have a very similar spectrum, just a bit more green. Maybe even with some 660 reds on the same circuit to keep R:FR ratio in check. It would be so nice to have just that little bit of HPS on tap, well distributed, for those colder months

never used such a red light lamp to cure your sinuses?
theyre very old tech.
beside any far red problem i think they will fry your plants in first, 2 feet away it will warm through your face in to your sinuses, very very feelable.
this is a spectrum of a halogen which also mainly heat.



incandescent lamps had been used in the 90s allready for the stretch effect.

your red lamp have at least lots more 600-700nm then the halogen, still going to be very warm as mentioned if its one like this.

Fire them up after the stretch is over?
Yeah but at what distance and what throw? Hanging it with anything low hanging like strips or similar is pita. It's hard to dose it out evenly and in a sensible way with so much power in one spot. I mean even if you add 5 w of this per square foot how would you make that work? Even 10w/foot, that's one little bulb for a 4x4 size space. It's going to be hard to get that even over cannopy.

That being said I'd love to see what it does.

then welcome back to the sane part of the forum.

yea, spread is very bad on those, in the end theyre made to blast you with some heat.

Ya I was thinking the wattage even at 150 would be a bit much. My lights are almost always 2ft+ above the plants so I could maybe sneak the bulb in with enough spread. 50W bulb seems the appropriate size for a 4x4.
Halogen bulbs are so damn cheap too.
