Yeah, F-series is available as 23v(2ft. single row) and with 46v.
A MW HLG-XXXH-48A fits almost perfect because of its voltage regulator. The voltage can be set within ±5v(43-53v).
If you limit the voltage at ~47v it's almost as safe as with a normal constant current driver because it would switch in CC mode below 48v.
But series wiring would be easier with strips and with a CC driver you don't need to worry about thermal runaways and uneven light distribution/brightness because of minor voltage/resistance differences between the strips. It's probably not visible but its there with parallel wiring.

the future is having lights that you can custom program the light spectrum though the growth cycle from clone to veg to flower to finish. There are a few companies that provide that type of li8ghtng already. I just build what I need, when I need it.
Another round fixture with some reds in it. Nothing new except the logo really. I guess they have to be careful not to compete with their own product line.

there was a discussion awhile back that all the fancy lights with the different adjustable spectrums yet none of the small growers really have the ability to use them or the control plants/metrics to dial them in and sometimes doing more harm than good for themselves. i agree somewhat.

I'm still not convinced that these custom, targeted spectrums even make an appreciable difference unless you're growing in a lab. I know that some horticultural scientists have done testing which supports this assertion, but there are so many factors involved that it seems like we're on the edge of theory here. With such stellar results from simple 3000k white LED, I'm really not inclined to give a shit.

Well, for that matter, I'm not so sure about ChilLED's boards either. When a number of growers using those lights demonstrate consistent, measurable improvements in quality and/or yield, then I'll be convinced. Until then, I'm a skeptic.

they look like quality boards
it is extremely difficult for anybody to exhibit a measurable difference with any of these techs as legit side by sides in a controlled environment are so rare. theres no magic spectrum apparently, though the new HE reds are high flux in high efficiency in a known photosynthetically active range

More hype than reality. Just a way to add more money.
Don't believe worth the extra cost.

Yes, everything I've seen from ChilLED looks like quality to me. I just doubt the value of their enhanced spectrum. Hopefully more of them will start to show up on the forums so we can really see what they're capable of. I'll be more than happy to find out that my skepticism is misguided!

I understand. I designed fixtures that do that for mew, using different drivers, switches and specific light spectrum cobs to tune in or out depending on light schedule. It just requires more drivers, some switches for blues, reds, far reds, with timers, etc. doable for the diy guy that is thinking. Most fixtures have switches for various selections for spectrum.
My current fixture has eight or nine MW style drivers for reds, blues, whites, etc. I am not as sophisticated as ChilLed and their driver technology, I just use more lpc style drivers.

There are so n ice companies out there. ProGrowtech for one uses a nice fixture MW drivers, various light spectrum and they use a system of strip lights, they are really nice.

yeah but for as much as we squabble, im going to give you some props that you live on the upper geekier end of what LEDs can do. Its a far cry from the half dozen "what kind of LED do i need to replace my 1000W HPS" questions i get everyday, if you know what i mean. Im not saying those programmable spectrums dont have a use, but they probably have more chance for misuse. kind led was a good example. that controller could do backflips. sunrise, sunset, reds blues, whatever, but fundamentally nobody utilized it and in any case phosphor whites applied uniformly woulda outperformed across the board. Maybe not the best example.

appreciate the kind words. My controllers are simple to setup and use. I do not promote dimming as it is a waste of money, but I do promote spectrum control. For a good light you cab set up four channels, white, blue, red and far red separate with easy no problem. That is why I designed it to be like the high end fixtures but easier to use.

I've seen some very good lighting setup's for salt water fish tank's that do weather effects.

..... and if we wait a bit, they let it rain too?!
With 3000°K/CRI80 we have a simple all-in-one spectrum that works almost perfect. If you want more red and far red, take 3000°K/CRI90.
These "gadgets" with lots of different colors are IMO unnecessary, are more expensive and offer no real advantage. For aquarists the look plays an important role, which is why these gadgets makes sense, in the garden we do not need these effects. If it really was that important, do not you think gardeners would have used colored lights in the past instead of warm or coolwhite(HPS/MH)?

Correct! I mean, if colored lights were really needed, the lighting industry would have built them earlier.
Efficiency is more important than individual color tuning.

I have a HLG-185-48A laying around, perhpas its time to put it to some good use.
