The specified lumens at 120 volts AC is pretty poor, huh? I hope that tolerance is a lot more than + or - 5%! LOL Fortunately as you are located in Europe, you'll be running on 240 volts AC I would guess. Edit: Mars Hydro also mentions "Sunlike UV & IR" , but there is no mention of those...

The OP bought an HLG-320H-C1750A , which is a constant current driver with internal current adjustment (no voltage adjustment on HLG CC drivers).

Hey man, according to your HLG link, you didn't buy a kit. You bought a Slate 2 triple heatsink and three QB 288 V2 R-Spec boards. This is plainly written under specifications on the HLG link you provided. Here is a link to the 320 watt kit...

That depends on the specific HLG "B" or "AB" model. 320 watt HLG CV + CC drivers and all 240 watt and smaller HLG drivers offer 1-10Vdc dimming. 320 watt HLG CC drivers and all 480 and 600 watt HLG drivers offer 0-10Vdc dimming.

Hey @jonnynobody , in your attempt to prove @PJ Diaz wrong you've made a small oversight. The TSW-3000 has been out for over a year as you found out on your Amazon search. No LM301B diodes though, this light is made with Epistars. https://www.ledgrowlightsdepot.com/products/mars-hydro-tsw-3000...

Thank you for sharing that. Have you seen any more information about the Kind LED inflated efficacy figures? I'm guessing Indagroove is referencing this light...

Do you have an Alibaba link or is this what Rita told you? Are you still looking at the Folux 240 watt kits or are these individual boards? If the 48 volt boards were really 1 amp maximum, Meijiu would have to include 5 boards per 240 watt kit.

Do you have a link to the 288 boards you're looking at? Some of the boards (304 diode boards for example) have a forward voltage over 100 volts and a lower maximum current.

Yes it's the same if the HLG 135 you have is a V2 R-Spec model (HLG currently offers the DIY kits with R-Spec Or B-Spec boards and there are older versions still in use). What driver does your HLG 135 have, a Mean Well HLG-120H-54A? If you get the same driver for your new board, it will cover...

Are you planning on vegging and flowering with these lights? Between the HLG 100 and HLG 135 You should be able to get decent coverage if you keep your flowering footprint to 6 to 8 square feet (closer to the higher number if the walls around your space have high reflectivity). As far as the...

Hey man, if you talk with the e-Bay seller again, do you mind asking what diodes are being used for the supplemental strips? It looks like the boards say Samsung like the Sun Boards with LM561C/LM301B chips do. I don't think Samsung LH351H are being incorporated into the supplemental strips...

The R-Spec board and heatsink combo has been $94.00 for a long while. The HLG 550 V2 R-Spec and B-Spec are on sale right now at LED Growlights Depot for $699 each. They're normally about $850...

Which drivers did you decide on for the Halo Fluxengines and 660nm Spectrum Booster modules? Did a Crescience representative recommend any specific models?

Hello @Stephenj37826 , I came across this light today sold by one of your International retailers. https://www.quickbloomlights.com.au/products/hlg-100-with-blue-and-red-spectrum-diy-kit QB 188 is printed on the board.176 LM301H, 6 Osram Deep Red 660nm and 6 Osram Blue 470nm diodes (versus 192...

Those ports are included for Daisy chaining multiple lights to each other.

You're right, I misspoke. Wouldn't Nonapus be a more appropriate name though? Anyway the Octopus name may be obscure and may not be apt, but it is different at least.

You may be thinking of Christopher's cannabis farming cousin. The Notorious B.I.G. said, "The more money you make, the more problems you get. And jealousy and envy is something that comes with the territory man."

There are 10 bars total on each Octopus fixture. 6 bars are wired to the 480 watt driver and the remaining 4 bars are wired to the 320 watt driver. Edit:There are 10 bars total on each of DrKiz's fixtures. The Octopus is a different light sold by Meijiu with 9 bars. I wonder where they came up...

@coreywebster was flowering a strain called Winter Solstice that looked absolutely beautiful just recently in a 3x3ft tent under four High Light UV boards on a 320 watt Mean Well HLG driver. https://www.rollitup.org/t/aussie-high-lights-were-official.1001681/page-16#post-15631790

They're not the same diodes though. Bridgelux uses 3 volt .2 watt nominal diodes (that they class as low power diodes) with a 2835 footprint for their EB strips. Samsung makes the LM301B/H and they are classed as mid power diodes. They are 3 volt .2 watt nominal diodes as well. They have a 3030...
