here a few of the most used and rather cheap LED brand.

spiderfarmer, hlg, ac infinity, vivosun, phlizon, lumatek, viparspectra, mars hydro

check their officials web site and compare, most of them have continentals warehouses, and officials websites ( .com, .uk, .eu, .au ,etc.)

For a tent size you usually find a range of 2-3 models per brand that will fit and scale.
Models with larger dimension and more Watt usually offer a more even light coverage and dispersion near tent borders but you may not use them 100% close to the plants.

Each brand will have their tweak regarding the spectrum, led layout, app, fan, orientability and whatever but truth is when it come to comparing the end results with panel equivalent in power amongst thoose brands you won't see much difference with the final results.

(i would avoid mars hydro TS series it's not uncommon some people had some issues with them, also i think most viparspectra new models are not fully dimmable but with step)

(i m with spiderfarmer, i like the simplicity of their fixtures and they had the best panel dimension for my 2x3 tents)

for a 2x4 tent you'll find 200 W to 450W models depending brands that will fit and scale in term of dimension and power
for a 4x4 tent you'll find 500 W to 800W models depending brands that will fit and scale in term of dimension and power

Well there's alot to unpack. While you want a true epar full spectrum (including uv and far Red (infrared/IR) because IR does infact drive photosynthesis, as well as raising the plants metabolism to assimilate nutrients similar to good Old HPS/MH/CMH abd the Sun, you don't want the ir chips in the same fixture because of life span vs the White and deep red (600-660nm) because the lifespan of the IR are around 10,000 hours vs 50,000-60,000 of the Samsung lm301h, 301b . So thst means at some point your IR chip's will crap out 5x earlier than the rest.

With that being Said, look for fixture's featuring at least Samsung LM301B, with LM301H/301H evo and either mean well, inventronics or sansen drivers, and add supplemental ir bars to it

With that said look into medic grow, gavita (not Samsung, but extremely good diodes ) or Also diodes by Phillips (green power) but those are less common.

Now are you after the best bang for you buck or Just the absolute Best with price be damned

Best bang is going to be vipraspectra pro series p2000 at 160$ , vipraspectra xs2000 $220(same as p2000 , Samsung diodes, but xs uses mean well drivers), ACI ION frame evo 3 $320, ACI ion grid

If price isn't a factor, kind LED x420 $550, hlg 350 Diablo $550 (id go kind over hlg), highgrove lighting magnolia 2 evo $400, hlg r spec 320 fr $450

Avoid California light works overpriced blurple $700 junk. There's More out there, Just follow that criteria listed above. Dr MJ coco's channel is a Great source of information based purely on testing and performance.

Personally I would go with the AC Infinity ion frame and add Mars hydro supplemental IR and UV that'll add about $130 to the fixture but it'll make it a badass start to finish badass lighting setup

These are all recommendations for the 2x4 4x4 that's a different category your best is going to be medic grow probably hands down across the board for best bang for your buck the smart 8 plus with added UV and IR from Mars hydro to the photon Tek or gavita being your best

Love the Spider Farmer SE4500
I'm running it with UV, IR, and Deep Red Supplement Bars

AC Infinity Ionframe Evo3 is an awesome light as well, it's advertised as a 4x2 light but the dimensions are better suited for a 3x2 (what I run mine in) but will still do well for a 4x2.

Spider Farmer SE4500 is 150 more Watts then the AC Infinity Ionframe Evo3. SF 430 watts, ACI 280 watts


The new Spider Farmer SE4500 is only 320 watts and only 3 led bars.
Try and look for the older model like mine if you get it, idk why they lowered wattage and removed a bar on the new version.

First 2 pictures Spider Farmer SE4500

Another vote for the spider farmer SE4500. Have 2 in my 2× 4 tents and have never had to crank them up past 60/70%. The only thing to consider is to be careful if you use them for seedlings, very easy to roast them if you don't pay close attention. I still have my SF1000 I use for seedlings.

Did you see they changed the SE4500?
After I made the same recommendation, I looked it up and it's now only 320 watts, 10 inches narrower, and 1 less bar (3 instead of 4). 😓

It has LM301H EVO Diodes now but for what they took away (wattage and amount of diodes), don't think it's better then our model with the LM301B.

Most growers would never tell a difference in their grow with LM301H vs LM301B.

No I didn't see that. Wonder why the hell they did that. Spider Farmer is active on this site, maybe we will get an explanation?

I called them out on it is the thread I linked below.

Post in thread 'Spider Farmer LED Grow' https://www.thcfarmer.com/threads/spider-farmer-led-grow.114948/post-3195491

I do like the new dimmer they offer with it, I wonder if it's compatible with the older versions since it uses an RJ connection.
I use a Controller 69 so doesn't matter but would be good information for others to know.
If the new dimmer is compatible with other models, it might work with any light brand that has a RJ connection on the driver.

Most growers would never tell a difference in their grow with LM301H vs LM301B.
Because there literally no difference, its just a marketing designation. H shoved into horticultural specific market, b being general light Market. As fsr as spectrum and output, but the H has a special coating to prevent sulfurization in higher humidity environments.

Buy there is a difference in lm301h vs lm301h evo

But on paper for horticultural use the Phillips green power has The edge over the 301h/evo.

When you said "our older Spyder farmer" , are you affiliated or work for spider farmer?

Uf it's a 0-10v dimmer it will be compatible with any drivers that use that dimming method and not resistive dimming.

Also you can use adapters for controller 69 to dim any style LED driver, type b for 0-10v, type a for resistive

I run all my lights with the RJ adapter on my Controller 69's
I like that it gives me 10 levels of dimming vs 4 or 5 if I was to use the lights I have without the Controller 69.

Far red vs far blue... What's the difference?

Any issues at all with light's acting weird or anything?

I planned on doing This with my medic grow smart 8 plus, but Read people had light's acting up when any non aci light's are used? According to Reddit...so i don't have much faith in those posts there

I only have 1 AC Infinity light and the rest I'm running are Spider Farmer, Vivosun, and HLG lights on the Controller 69's with no issues at all.

It even allows you to use Sunrise/Sunset mode, might not do anything for the plants but I think ramping up lights puts less wear and tear on them.

ACI had a firmware update about a week ago that added an option to change the adapter settings for RJ connections, that is supposed to fix any issues with light's that use to flicker

Fsr Red is all the way right on spectral charts, 700nm and beyond, most peaking at 730-760nm infrared/IR

Far blue is all the Way left on chart, 405 and below 345nm-405nm ultraviolet/UV

Uv doesn't drive photosynthesis, but stimulates secondary mechanisms. Resin, disease resistance, etc. far red does in fact drive photosynthesis a good bit while also stimulating others secondary mechanisms, like metabolism, shade avoidance, Emerson effect, etc

With implementing far red you can extend flowering lights on to around 13.5 hours,. You give it far Red 20 minutes before light's off and let it's run 5-15 minutes after light's off and the plant immediately starts producing florigen instead of the normal 2 hours or so after light's off. So the plant reaches trigger and maintenance levels of flowering hormones much sooner in lights off cycle.

Appreciate the info, thanks. 💯
