When they first came out with it if I remember correctly it was the early 80’s. They sold it for around 5 years and then discontinued the horizontal version. If it is ok to run it in that position, it should be on the packaging. Some are vertical only some are horizontal only and some are multiple position on the HID’s.
Been running LED’s exclusively for years now. I do supplement with far red and UVC.
I just didn’t know that they had make it for horizontal use again.

That will prolly just be the same as your MH bulb which really is a vegging bulb & not ideal for flowering, i think you already use them in a flowering area too with red 2700k flowering bulbs. But i would say anything rated around 5000k upwards would be sky blue.
What does uvc do ? i know uvb around 280-290 lighting wavelength adds potency and uvc doesn`t cus its wrong wavelength. TBH i always thought its more of a snakey type product that’s produced by greedy LED light makers, cus LED cant actually produce uvb yet or they couldn’t last i looked.
I also think far and deep red led suppliments are a little snakey although it does actually do summink to help plants out, but modern led contains both far and deep red like they do uvc as well (sorry my bad its uva that modern led grow lights contain not uvc). Hence the snakey tag for red supplements cus its already in your grow lights.
Are they just cash money makers for light makers and a bit snakey cus of said reasons or not ? Summjink I’m still pondering call me a old cynic mate.
Might check out the episode of We The Growers with Beanfiendz (Mobile Jay and Mitten Master). I figured the far red thing was hokey too, but they found out how to use it to really good effect.
I’m not saying its total hokey pokey and i do know what it does. Maybe i should put my point across better. But i was meaning is it snakey cus grow lights already contain the stuff ?
I gave all my supplemental lighting like this away, although i didn’t test anything scientifically imo it did squat that i could tell of for my weed. I seem to remember i used it for 30minutes and it came on 15mins before lights on and out so it was only running 15mins both ways during dark, maybe i was using it wrong feck knows tbh @BigF .
I used a UVC light to help control powdery mildew, at least until I found @JoeCrowe 's sulfur tutorial, lol!
Anyway, had to be real careful with it. Can be harmful to skin and eyes besides the fungii. Too much would also mess up the foliage.
I am surprised it would be in a grow light. It’s my understanding UV-A&B naturally pass through the atmosphere, but the ozone layer keeps the UV-C from frying us. 
Ahh got you on the mold thing for sure yes. TBH i was getting the ultraviloet light spec wrong. As said uvb wavelength around 285nm for added potency then uvc wavelength kills spores etc, but yes it was the uva supplemental lighting i had in led that did very little to squat-diddly that is already in led grow lights its not uvc. My bad their ouch sorry guys. .
So is that uvc LED you use ? i really didn’t think LED could produce that uv wavelength and was only able to produce uva light, Not looked in a very long time though Horsey. Plz forgive my uv misshap i was getting A B & C in a tiswas their. 
P.S
Come to think of it now i remember you buying that UVC wand for mold time back now man.
It’s a bit more than a wand, mate, lol!
Right, I think one of you circlers sent me that pm! Nah, not really, but I did mysteriously get it while having a discussion about rot there.
Anyway, the UV-C did a job for a couple of years, but never really could eradicate it. Sulfur eliminated it, and I’m glad I don’t have to wave that thing around anymore 
I’ve never seen a grow light that put out UV-c, I just commented because I was wondering how @sssportsmfg was using it. Too scary for me 
That`s the tool i remember you buying yes it looks like a bloody euro hid light reflector i have, not bloody cheap either Horsey.
Yes glad you put me right on UVC i did know but got my wires crossed with UVA prolly cus he was using it in his grows, i would like to know how and why he uses it too, well that’s my excuse anyhow
I did take a quick look at the use of sulfur in the thread for PM but i only looked at first few posts which told you how use it. But I’m glad you got it sorted all be it 600+ bucks in and more with the big uvc and rest of crap i bet you used trying to eradicate the fucker. Sorry about reminder 
They were using 4 to 6 minutes of far red at lights off. They found that it shortened flower time quite a bit, with no loss in yield. If it was coming from just about anyone else I would call BS, but Mobile Jay doesn’t have a single BS bone in his body, wouldn’t even know how to sling BS, so it was an eye opener.
I think LED is missing a trick, it’s got an ace up it’s sleeve but it’s not using it. They’re so concerned with form over function, designing different layouts, panel and ladder etc but they’ve completely missed what could be the best aspect of it. It wouldn’t be that hard with the different LEDs of different spectrums to build in a small PLC as a brain and make a light that mimics a true day, starting with a golden sunrise, a clear bright morning, intense midday and tapering to golden hour and sunset. No idea if there’s any benefit to the plants but I’m amazed they haven’t tried to make it and convince us that it’s the new best thing.
IGOR ur on to something groundbreaking with this idea I think anyways u should try n pitch this to a light company or maybe patent it lol I’m know ur busy as heck but this is a great Idea 
Its all about the money imo and I’d say they make more selling separates than one unit cus we all know tech is their to do this and its gonna prolly be done at some point, prolly when all sales have been exhausted of other lets call them “older tec units”. Just a wild guess though Igor.
So i think these are around day 19 in bloom now and tbh the stretch from these plants is very minimal. In all honesty one of least stretchy plants after flip that I’ve grown in those first 3 weeks after flipping to bloom. I thought it would be a lot more what with strawberry diesel in the mix. Very much thick stems that could stand on their own when in full bloom, with this plant, without any support. Cheers guys.
EC this week was whacked up to 2.2 and ph is in range so jobs a good en guys.
They’ve really filled out nicely in the ten days since the previous photos. Great work mate.
