Hey man, HLG is no longer producing boards with LM561C.
Is that what you meant by 7 year old tech?

Well, deffinetly not "The" QB, but the same style, flat pcb of mid-powers has been going strong as the drop-ceiling floro replacements since as far back as "15" that i saw remodeling a KFC.
Keep in mind, many lights, models, form factors & ideas come from the street, office & warehouse lighting industry.
It's making these type fixtures most efficient for growing that is the difference.
SK is a high-bay wharehouse housing. Flat pcb mid-powers were designed originally as floro replacements. Troff lighting ect...
Taking those ideas to the next level is what allows many growlight companies to keep it moving. There's only so many ways to deploy the photons.
I do not agree that it is old tech as the tech is in the diodes/driver which is always being updated.
Bar lights & Strips are not old tech just because BML made the Spyder 7 yrs ago.
As long as the design is providing the optimal coverage for its style then it will always be used.

If you are limited to those fixtures & that's it then I'd pick the Chilled GrowCraft (although am disappointed in their spectral choice)
All lights mentioned have the similiar HE spectrum except maybe the Optic-8 but I'd stay clear of Optic Led. You know a led comp. does not know what they're doing when they add 450nm royal blue to a white light. But i guess, To a degree, the same could be said for all these companies that primarily regard electrical efficiency over splitting the difference or trying more for Horticultural spd's. The results are still outstanding so no need to change for some. Just getting 660 added to their plain white is a big deal to many & has shown improvements.
Slim was listed at 2.7 & now is 3.0 umol/j? As AirWalker16 said, & i believe he speaks from experience. The comp.Optic Led is Poo.

Everything but the Optic-8 will give you similar results (that will provide the prettiest bud probably) if hung high over a 3.5x3.5. Longevity (thermal mngmt, diode spacing & quantity) customer satisfaction, build quality, warranty & the known use of top-bin diodes & quality remote drivers is what sets these listed fixtures apart.

You own a gavita 1700e?Does that use the new LM301B led's? That thing looks awesome! You're not wrong $$$, plus the controller and adapters. I need 2 to cover 5x10. Just can't seem to pull the trigger.
wow quite a fantasy you posted. Fiction is definitely your forte
Im referring to the mono spectrum as being old tech, not smds
I was not aware that SF ratio is 1:1, that's no bueno. I will stop recommending them, although I have seen some killer grows on another site
Thanks for the Fissioning link. Looks worth recommending, but you've recommended several, so confusing

I've reccomended Fissioning pretty much exclusively the last couple months.

EDITTED: I would try them to replace the center isle of lights which do not need to be more then 150w per 3x3 for me. Need flat boards that can press close to the ceiling. Would have to be remote drivers even if short leads.
Their diode layout is perfect for boards.
Did not know they had 660 + 730 nm.
Thought they were just white.
Wonder if they'd consider other colors too?

They got 660&730nm on em, and with the 3500k cct, it's a really nice spectrum

pretty cheap but no driver, I think this is a nice deal here and may be an error on their site

Certainly not a mistake. If anything, those triple slates are pretty long and are most likely sold less then others items. Still quite a bit of cash.QB288 V2 Rspec & Slate 2 Triple

Thank you man, although personally I consider myself multi-talented.
On another note, I am relieved that you seem to have come to your senses.

So your saying the optic has the best quality wise?

Maybe I missed a reply, but I don't think anyone recommended the Optic lights.

Im currently running a FluenceBioengineering SpydrX Plus in a 5x5 and a HLG 550 V2 Rspec in a 4x4.And i can tell you they are both great.But i like the fact that HLG uses less electric 480 watts compared to 660 watts from my SpydrX Plus but the heat sink needs a better design.Gives off more heat then my SpydrX Plus.And the SpydrX can be as close as 6inches away from the tops but the HLG has to be around 18 to 24 inches away.But depends on ur needs.The SpydrX Plus was 1500 whereas the HLG was almost half the price.just my 2 cents.

Hell no. All of their lights are re-branded SunPlusLED Fixtures

The Optic Slim 600H has more LEDs than most higher end 4x4 lights(factoring in the price of top bin Samsung LM301H), 2,760 in total. Assuming they actually use top bin chips, that is somewhat impressive.
I'm not a big fan though of the fact that they used the several generations old Cree XP-E for the mono-colored diodes on their light rather than a newer, more efficient diode.
The ChilLED GrowCraft X6 1000 watt looks like a damn nice light, but as @coreywebster said, a bit of a waste light-wise in your current space unless you run it perpetually dimmed.
In your situation, I would buy the HLG 650R. It has a strong full cycle spectrum and has just about the highest efficacy of any LED grow light on the market(the ChilLED light is of comparable efficacy, especially if run dimmed throughout its life, although that may make the drivers run slightly less efficiently). HLG is a reputable company, that stands behind their products, not just pushing another companies re-branded lights (this was the case with Optic LEDs older lights, not sure about the Slim 600H). HLG also has two representatives on this forum. Also if you like the high diode count of the Slim 600H, the HLG 650R has almost as many, with 2,664 diodes in total. 2,592 Samsung LM301H and 72 660nm deep red Samsung LH351H.

I would be honestly very VERY surprised if the 600H isn't on Alibaba under a different name built by another company just as they did with SunPlusLED.

I'm almost inclined to believe it's these strips from Meiju, possibly just on a fixture that they have built for them. There's tons of folding lights, but I can't find one that's got the same hinge.

Yes, the 1700e uses the new chips. It also uses Osram Far Red chips...I believe the 1650e used the older ones.
