2000 watt grow replacing 1 light with LED newbie

Hi
I have a 4.5 x 8.5 with 1000 watt mh and 1000 hps.
I am looking to get into LED and replace 1 of the lights. Ive been looking at HLG, Timber and Rapid LED. Im fine with assembling a kit but don't really want to buy just a list of DIY parts right now.
What would you guys recommend and which HID would you run with it?

Made by the well known R2T for 470 Dollar with 600 watts of LM301B + all you need like a driver .
It seems they have also the 2700K like in their description , i would choose that color for flowering.

The wattage is there but i fail to see how the form factor is going to acomodate for 5 feet wide when the light is about 2 feet wide.

Under 1k is quite hard. But something like this or with a bunch of Fotop boards its almost doable. 6 fotops at 200w each using 2 hlg600 should be just under 1k. Some cabling, alu angle and wago and youre good to go, the Fotops dont need heatsink, just make a frame and, attach boards and connect and go.
But thats for the whole space, is this just for half?

yeah Im going to run a 1k hid next to the led

Theres a reason for not doing that: hps needs lower than 80F temps, leds usually over 80F, unless you make sure both lights mix properly. Missing infrared heat is the reason why.
right on. I don't have the budget to switch out both at once though.

But i think you actually do, at least as far as chips. Also if your space is vented and a bit cold at winter it might be a point in getting you a setup that can run both leds and hps at the same time: there might be some months during winter where you need that thouie for heating. The way to do it would be having it hanging relatively high in the middle, with leds on the sides.

Have a look at the Fotop thread of Moflow and check the updates from @WeedSexWeightsShakes.
You should be able to get them both thru search.
Get a feel for how the fotops look and how they lay down their footprint.
You can get 6 shipped for around 550-600us$, if you go board only and stick to lm561c.

The 6 will do your entire space, but it might be hard to get the rest of the setup on only 400. But you wont need everything just yet.

Check if you can find an inexpensive aluminium shop near by, if you could score some alu sheet cut to custom length. Use 1/8th inch, 14x38" approx. This way you can take your boards over 200w.
Get a couple of meanwell hlg240-48A, or even 48AB if you can score them. Dont buy them from china. Buy it from somewhere you could return the more or less easily for warranty, they have 7 years and its a pain to shipp them.to china. Use digikey or arrow electronics. Or even mouser.

So 6 boards (ask them for some wago connectors aswell, they got them cheap in china)
About 550-600
2 drivers about 120 with the cableing.
Alusheet: i get this size for around 10€ here, guestimate 30$ or so.

And you will have a fully working light that covers a 4x4 or 2 4x2. And you will have the boards to be able to expand to more with just some minimum investment.

The spiderfarm light dont seem half bad but they have the same problem as all the hlg550 clones: concentrated light source. It gives shitty light levels in sides and corners of a 4x4 and your space is slightly over that.
For a full on led summer setup: 2x3 boards on about 1200w in total.

Sf4000 spider grower same as hlg and alot cheaper uses samsung leds lm301bs awsome light
It's not the same. HLG uses similar quantum boards but SF understands spectrum blending across the entire canopy, assuring each sft gets balanced spectrums

2 SF 4000s should not require any COB supplementing, BUT, would benefit from ~ 10% extra IR and 5% 450 blues

Hmm. Care to elaborate on how Spider Farmer happened to arrive at a "balanced spectrum"? Do they have the data to back that claim?

Uh, no..... completely backwards.
Horticulture Lighting Group uses Quantum Boards. The name Quantum Board is owned and trademarked by HLG. In fact, they are the only company in the universe that uses Quantum Boards.

See you got yer Quantum Boards, and then ya got everything else...
They may be functional sure, but they ain't QBs. They just ain't.

Sure. Plants respond to a wide variety of spectrums which SF (among others) incorporates into each sft, whereas HLG only has 3000 or 4000

But what makes SF's spectrum balanced? How have they determined the correct ratios for "balance"? And you must know that a 3000k LED is more than just a single wavelength.
