Looking to add far-deep (660-730nm) red strips/boards to my setup, what to buy?

After getting my first quantum boards that are just full of "basic" 3000k white lm301b's led's, i've been eyeballing to add some extra red to my existing setup. So here i am looking for knowledge what would be the smartest choice with a smaller budget. Bought my QB's from Kingbrite since they were easily the cheapest option at the time with pretty cheap shipping, and so many people were giving thumbs up too that i couldn't resist. So far haven't regretted that choice.

Since i already have 1152pcs of 3000k lm301b's (~500W) in a 4x4 tent, i probably won't need that many extra lights, just a smart amount of extra supplemental lights to give extra boost and coverage to the whole tent. Of course adding more lights means i could run my QB's at lower power too.

I'm not sure if i would need to buy more blue or go UV/IR since they seem to be even more expensive, but i'm open for suggestions.

So i was looking around Alibaba (i know i know, "the cheap knockoff site") and Kingbrite seems to be one of the only cheaper companies selling boards/strips of 660nm & 730nm CREE XP-E2 along with Epistars, which seem to be over 2 times cheaper than CREE's. I looked around a couple other bigger suppliers and tried to search around the site, but there didn't seem to be much other "red only" board/strips around.

The only other companies i know that sell these are HLG & Cutter, BUT keeping in mind shipping to northern Europe most likely limits my options to Alibaba or some European site, and i don't know any European sellers. I checked HLG's site and they were sold out on these lights, like they seem to be with most stuff every time i've checked :confused:. Cutter seems to have much bigger arsenal of choice, but being an Australian company they might be out of my league in terms of price/shipping. Correct me if i'm wrong in this, so far Alibaba has been the only option with their unbeatable prices. I would pay a little extra for other than Chinese sellers if i got warranty and all that jazz, but they're just selling the same stuff with up to 2-5 times the price i get from Alibaba.

So Europeans fill me in with good suppliers that have reasonable prices (if there's a single one), there's no way in heck i'm gonna spend twice as much money on lights that come from Chinese producers anyway with added bonus for the importers :rolleyes:, i will always go straight to the producer if possible, unless it's not convenient.

I would need a driver too along with the boards/strips, at least Kingbrite sells of both those. And i'm sure they're willing to customize kits too, dealing with them was rather easy when i wanted different drivers for my kits. I looked up a couple of examples from their catalogue, there's much more too:

660nm CREE XP-E2 20pcs board w/ MeanWell APC-35-1050 driver ($41.5)
660nm CREE XP-E2 11pcs board without a driver ($14.5)
730nm CREE XP-E2 11pcs board without a driver ($17.5)
730nm + 660nm CREE XP-E2 20pcs strip w/ a MeanWell APC-35-1050 driver ($45)
660nm Epistar 52pcs board w/ MeanWell APC-35-350 driver ($29.5)
730nm Epistar 52pcs board without a driver ($32.5)

I know some other brands exist too but i don't have knowledge about those. Pretty much everyone on Alibaba sells Epistars along with their QB's, but how are their quality compared to CREE's and others?

And lastly what would you suggest to buy in my case? My budget would be between $100-200 for the lights and a driver (or drivers, maybe just 1 is enough), i'm sure that would fill my needs at least with those Alibaba prices. I just don't know what/how much to buy and should i mix 660's with 730's too? Cheers :eyesmoke:

Take a look at led-tech.de. They have some Osram Hyper Red (660nm) strips (amongst other things) shipping from Germany:

https://www.led-tech.de/en/50cm-Osram-SSL-Horticulture-Hyper-Red-Plug-and-Grow-Stripe

I don't think they have any combined 660nm and 730nm strips though - but they do have individual leds on boards.
Thanks for the link, i only found these 3 red strips w/ heatsinks (would heatsinks even be necessary with strips like these?) on top of the one you linked (not sure if there are more anywhere else?), would also nice to see more information what exact LED's they're using in each set, i had some difficulty finding the models they use from Osram's site:


I wonder how these compare to CREE's and Epistars? Osrams seem to be a lot more expensive per unit at least there. Does led-tech offer any warranty for these things, couldn't find anything about that? At least shipping costs seem to be reasonable.

And would need to figure how small driver could drive at least 4 of those strips you linked. I don't know if those would beat the different REDS sold in Alibaba. I don't have any brand loyalty or anything like that, so i'm gonna go with a set that provides the best price/quality ratio.

Also i don't have space for bigger boards, so they have to be some kind of longer stripe style boards/sets that i can just drop straight next to my Quantum Boards for even larger coverage. I'm probably not gonna stop until my tent is 100% filled with all kind of different LED's. I'm starting to get addicted to this hobby, sure i'm not the only one here :D I don't mind some DIY stuff, but if i can get by with easy to assemble "style" products without wasting money, then i'm going with that. But just like PC's, i love to choose and assemble all the parts myself to get the best fit for myself.

They have a new veg board too.
I have had good luck using supplemental hlg bars that have 470,630,660,730 in them to compliment my 3k boards.

Like i mentioned in the starting post, HLG ain't for me UNLESS i happen to find some cheap used lights from them by a massive chance. Looking for red bars here.

Any of the red mixed bars off Alibaba if you don't wanna pay HLG. There are other options that are inexpensive as well from trusted suppliers. IMHO, if you have x4 single boards you're trying to enhance, id place them evenly over my space then fill the + sign in the middle using low wattage strips.
If you have a 550 style qb like I posted (all in one) then a 60w bar on each side id go for.

I couldn't even pay HLG if i wanted because they're always out of stock (just go take a look :D), and the shipping costs on top of the already higher costs would kill me (unless i got their lights from sale).

Yeah i have 4 single boards i'm trying to supplement, now i just need tips where to buy, what lights to get and how many of them would be a good amount to fill out some empty space in a 4x4 tent.

So you say any of the red mixed bars, no more specific recommendations if i should get CREE's over Epistars or something else? And should i just buy as many of them money can buy?

Cree's or Epi's depends on your price range. Another option is epi's run softer then intented. Then they'll last longer, & all you're doing is supplementing. Doesn't take much.
If going cree or a better brand I'd consider 100-120w , filling the gaps inside the x4 board configuration. If you're adding to plain white 3k the I'd consider a mix of:
- 400,430,470nn,630,660,730nm, 65k.
or broadband chips like Optisolis with extra reds.
2, 30w, 2' bar/strip, x1, 60w, 46" bar/strip. Even half that wattage will make a difference so you'll get more then half the light from epi's. Food for thought if using monos.

If you're still looking at options, check out RapidLed. They have some solid looking supplemental bars. They also have pucks somewhere on the site too. I've been thinking about ordering the exotic or mass medical (sold out currently) to add to my setup

I was thinking on staying on below $200 budget, not gonna go crazy at once. Of course i would love to get all the different lights to get very optimized and balanced setup, but i'm not that concerned about that now. So i was thinking on filling the reds for now unless i happen to find some super deal somewhere. But my options are very limited because i'm not made of cash either :(. Well i can get more later tho.

Still checking out my options what should i put together. I don't think RapidLed would be an option for me based on the prices, North American sites are pretty much all out of option because the shipping costs alone don't make it worth it for Europeans. From Rapidled you would have to pay $70 just to ship one light here, maybe now you understand there's no point to even suggest these companies to me, unless you can find one who doesn't only offer competitive pricing, but also decent shipping costs.

Okay let's say you have around $200 budget for the reds and the driver (i think shipping is like $30 if we include that in the budget, might be a little more if i buy more strips, a driver and other components at the same time), what would you buy for me from Alibaba? If you wanna throw out a fast shopping list.

Or do i just buy a mix of CREE's or Epistars, which ones would be your choice? I might need help choosing a proper driver for the set too, there's so many different options/models available. At least MW seem to make decent drivers, and they're included in pretty much every kit sold in Alibaba.

Also are heatsinks necessary or recommended for these strips? I'd guess so if they get hot even with less than 20pcs of LED's in a straight pcba board. Just thinking if there was some money to be saved by negotiating a good deal, but i guess they aren't very expensive to leave them out either. At least Kingbrite is selling their standard heatsinks $8.50/piece, so just a raw calculation by dimensions would mean a heatsink for their QB11 CREE strip would cost only $2.25. I'm sure they would cut the price even more with a kit.

Quick price references from Kingbrite and lenghts of the strips too if that matters in any way in this case, well even the shortest ones are almost twice as long compared to my ~13" x 8" (32.6cm x 19.5cm) QB's. I can start filling that + sign in my 4x4 (120cmx120cm) tent:

lenght: 21.5" (56cm)
(QB11) CREE XP-E2 660nm+730nm (6x 660nm's & 5x 730nm's) = $17.50
(QB11) CREE XP-E2 730nm (11x 730nm's) = $17.50
(QB11) CREE XP-E2 660nm (11x 660nm's) = $14.50

lenght: 35" (89cm)
(QB20) CREE XP-E2 660nm+730nm (10x both) = $30
(QB20) CREE XP-E2 730nm (20x) = $30
(QB20) CREE XP-E2 660nm (20x) = $26.50

lenght: 37" (94cm)
(QB52) Epistar 660nm+730nm (26x both) = $17.50
(QB52) Epistar 730nm (52x) = $17.50
(QB52) Epistar 660nm (52x) = $14.50

The rest i would leave to a LED wizard who can recommend a good set with those things in mind.

If keeping simple the Emerson 660+730 strips. KingBrite has the strios & deals

What about the red to far red ratio?
Maybe I'm not reading the above correctly but I see the qb20 has 20 diodes total, 10 x 660nm and 10 x 730nm.
A ratio of 1 to 1. Seems a lot of far red to me.

Might be out of his price range but it's going on my list for my upcoming DIY build, those are glorious!
