That's only 19w/sq'. But i saw the video & have a Trinity so i understand. It looks like it will & it will, but the edge #'s are allot lower then the guy in the video thinks. Growth looks green there but that's how those tend to work. He could raise the light for more even #'s but its still only 19w/sq' from a central based bare diode les. If there were a few creating cross lighting then maybe 4.5x4.5. They are real bright to the eye. Especially because hang high & no edge reflector or eye protection as well as very electrically efficient.
What did we figure my bars to be? 27w/sq'? Dont remember.

They don't. According to their website, they suggest for flowering a 550 will cover a Flowering Footprint: 4.5' x 4.5' or 4' x 5' at 24"

Where does HLG claim that?
Comparing HLG 550 R spec vs HLG 650R
Comparing Efficiency, output and performance for HLG 650R vs HLG 550 Rspec Commercial LED Grow Lamp. In Depth comparison for high efficiency Horticulture Lamps. HLG 650R replaces a 1000W Double Ended HPS and HLG 550 R spec replaces a 1000W Single Ended HPS.
horticulturelightinggroup.com
Not here or on the HLG 550 R Spec product page. The only references to 5x5 areas that I can see are the PPFD maps recorded by Light Laboratory, Inc.
To answer your question, I don't have experience with the HLG 550 R Spec, but I do have a smaller R Spec light, 2 QB 96 Elite V2, and 2 four board QB 132 V2 fixtures. I have found HLG's stated coverage area for their lights to be accurate.

Dunno where they are made.

Jk right?
They only call it that because its a 550w COB light equivalent. (Not letting me use emoji's) ; )
Lol!

Yeah, looks like you're both wrong there with your previous postings of the stats.

So I'm off by 6" on the Data sheet
I was correct on wattage and recall the conversation of GrandMasterLevel covering up to 4 x 6 with a HLG 550 - 20W sq/ft??

I was always under the impression you could turn the vO pot up to Max out the driver to 550 with having 4 boards on it. Guess not.

Again, I thought you could Max the vO potentiometer to get that extra 70watts/(17.5per board) outta the driver.

Wired in series, no internal vO adjustment.
Used to use an HLG-480H-C2100A, before switching to the Inventronics drivers.

Oh they don't even use a 480-48A? Man... Ya there's no way it goes to 550 then.

No you were off by by 5 square feet; 25 sq ft you quoted, vs 20 sq feet which is the actual rating for the lamp. So you were off by 20% there.
And as far as wattage, you under rated it by 20 watts; up to 500w actual vs 480w your rating. That's around 4% difference.
If you are going to make speculations, please make sure they are accurate, and not false news. Overall you under-rated the HLG 550 by 24%.
Where were we again?

If you use an HID in a 3 x 3 you need a 600w, and use nothing but a Hortilux Bulb. Thts 66w Sq/ft.
A 1000w Hortilux is made for a 4 x 4 in is 62.5w Sq/ft
A Gavita 1700e which is a direct replacement for a 1000w Hortilux HPS is 40w Sq/ft, and uses the best samsung Diodes.
If you want the best production, use nothing less than 62.5w Sq/ft if using HID, and 40w Sq/ft of the best Samsung Diodes. Anything less will not be optimum.
I use a Gavita 1700e, Hortilux HPS 1000w, and 1150w Gavita DE HID. I usually veg under a 1000w Hortilux HPS from seed/rooted clones, but am experimenting with a Gavita 1700e for veg at the moment.
Hortilux 1000w is 1600umol
Gavita 1700e is 645w, and 1700umol
1150w Gavita DE is 2100umol, and is intensely hot, and extreme IR. It also needs to be at least 36-40 inches from top of canopy.
Gavita says the 1700e.. 40w Sq/ft is a direct replacement for 1000w HID/Hortilux HPS which has the highest umol for a single ended HID, and is good for a 4 x 4 area.
