You have a good point. Some of the page has good information, and some looks not very well edited (out of date or incorrect info). Did you see the page for the pre-order HLG 135 kit? They state the HLG 260 for the HLG 135 price. I wonder if anyone had a quibble with that mention.

Are you referring to the HLG-UK-EU website? What false claims are you seeing? https://horticulturelightinggroup.com/pages/international-distributors

Here's one: https://chilledgrowlights.com/our-products-services/commercial-led-grow-lights/5ft-x-5ft-canopy/growcraft-x6-1000w-led-grow-light-commercial-grade At 42.5" × 42.5" × 1.375" it will fit. Obviously it would need to be dimmed substantially.

If they're the HLG drivers for the 260 watt kits, most likely they will be HLG-240H-C2100A.

It's an HLG-320H-C1750A

HLG uses 3500k Samsung LM301H whites and Osram Oslon SSL 660nm for the QB 288 V2 R Spec boards. 4000k Samsung LM301H whites and LH351H 660nm are used for the QB 648 (666 diodes total and dubbed the Diablo by HLG). HLG pulled these boards and the DIY kits using these boards off their website...

Is Invertech really the type of driver, or did you mean Inventronics?

I was a little surprised by this myself at first, but the QB 288 and QB 648 (666 diode Diablo board) boards have the same Width x length dimensions: 11.25" x 6.833". The HLG 600 RSpec and HLG 650R also have comparable width x length dimensions.

Thank you for sharing your thought process. Are you able to adjust the wiring on your veg fixtures driver input so the outer jacket of each cord fits into the strain relief area of the 3 way connector? Or is the connector too small? If that can be done, the connections will be more secure...

Hey @NeverOutgunned , have you seen any mention of what Mammoth is using for the 660nm diodes on these lights? Here's a clickable link for people who've yet to see the lights...

Very nice. That reminds me, I've some lights I need to put together. Did you have a practical reason for going with "B" version drivers for the flower lights and "A" version drivers for the veg fixtures? Or was that just what was available at the moment?

Hey Padawan warrior. For better or worse, some people are on these medications for the long term.

That would be @Fevs.. He has a GN Telos 6 and maybe a Telos 10? It's not easy keeping track of his assortment of lights.

Well they're both Mean Wells. Different series of drivers though. HLG vs. XLG series. They have their similarities and differences. AFAIK the XLG-240-H-AB is used for the SF-2000 and SF-4000 (x2 drivers). Formerly 240 watt ELG drivers were used for those models.

You thought highly enough of them to recommend the light. You don't usually go around recommending shit products, do you?

Yes sir I accuse you of favoring them. Lol You recommended HLG to someone just 3 months ago: https://www.rollitup.org/t/led-light.1021568/post-15619772 I would rather not argue with you though. Can you try to appreciate that sometimes people have different outlooks and opinions than yours...

@Aaronsgooter RIU10 or DIY10 can get you 10% off on HLG's website. HEY @bk78 . I know they're not the most inexpensive lights, but I remember a time not too long ago that you thought quite highly of HLG.

You're not looking at the wrong thing. However you can't max out the load to reach that wattage with 2 QB 288 wired in series to that driver. To get near that wattage, you would need to be closer to the drivers maximum output voltage of 143 volts (rather than only 70% or a little more of the...

The XS2000 use an HLG-240H-54AB don't they?

Here's a chart from the Spider Farmer website. I'm not sure why minimum power, maximum power, and factory set power are not listed for each model. As far as your warranty question, take a look at the postscript near the bottom of the shot. Please pay attention (joking)!
