Hey Shane, thats the older diode layout on the Sf4000. There is a new diode layout on the latest version, I would love to see the specs on that model! thanks

[@jawnhuh4275]

I love this channel and appreciate all your work. Love the attention to detail you include

Glad to see you're still awesome I can't wait to see the next light review and testing

[@OGRadGrow]

Hey Shane, I recently purchased a SpotOn Quantum Par Meter. My decision was based on your review of the meter. This is the first Quantum meter I've ever owned, but I love it so far. Very easy to use. Im happy to see you're using it as your go to meter now. Thanks again Shane.

[@modernhorticulture]

That's the older style one. They released an improved version a little while ago with vastly improved light spread.

Hi Shane, could you also give us unit size for the lights? - my maxibright and lumateks are ~900mm Sq. so we have a better idea of the tested lights in our grow space. Thanks!

Spider Farmer makes great lights but I’m not a fan of their SF series. You should make a video on their new SE series which uses bar lights, they look good quality

A good review, nice light.. I bought a while ago a light you tested that was sort of the same but with reflector ,400 watt model but with higher ppf corner scores more red diodes on the board than the sf4000 , the name was -IMVSincere 400w light that light cost what a third of the sf4000 .. I was a little unlucky having blue lights here because of another person and got cought so i was happy being able to set up a new grow after because of the price i got that light for ,what was it about 160 pound delivered to my door from irland, man thanks that helped me really out... I just ordered the Maxisisun mg3000 so looking forward to getting that light ....... Next time i can hopefully gett one of your lights now the prices have dropped and im in a new situation .. So thanks again man , love your honest reviews and product ... 10 thumbs up

[@seadonwhite9096]

I understand that efficiency wise the light isn’t bad, and as far as light spread, it is even. That being said, to advertise this light as being suitable for a 4x4 I think is a misnomer. I realize it will work but not as well as a 600 watt board or bar style that has a wider footprint and wider useful light spread. I have seen cannabis flowers in a 4x4 with this light hung correctly and they don’t compare in structure and density to a 630 watt bar style. I think this is a 3x3 light and then I think it’s spectrum leaves a little to be desired as far as really good flowers go.

[@landonl958]

I bought the SF2000 over a year ago after watching MIGRO's video on it and I have never been happier. I use only 200 watts on that baby and it has paid itself back three-fold now because I live in Colorado. I paid 300 for the SF2000 at the time and let me tell you, that bastard can grow ANYTHING!!! (Because Colorado ;) ) I have passionfruit, mango tree saplings, and pumpkins growing in my bathroom now, along with some different micro-greens I change out every day. There is a current October sale going on at Spider Farmer ATM and it brings $40 off the current price, coming down to $489. I tried adding the MIGRO code, but because of the October code, it won't let us see how much the MIGRO code takes off the price. I hope this info helps you all.

@@landonl958 if microgreens are your thing the Mars hydro sp3000 are worth a look as far as I can tell, the ppfd is by far the best

Years late to this light Shane .....they have bar style lights now .....you should of reviewed this when it was very popular and selling like hot cakes

[@budstermcgreen6360]

I don't understand why they wouldn't send you the updated light with the better diode layout. Similar to the atrium. To my knowledge there isn't a review/par test on it anywhere I can find except for what the manufacturer provides. Seems to be a decent light so far. I just finished my first flower cycle under one and pretty good results. The SE models are even better looking and going to pick up a 7000 in the future. ✌️

[@pursaveer9027]

I have 2 SF-4000s. There are much better lights for the money, in my opinion. The light spread is poor, and the heat concentrates in a small area. A few pennies worth of additional aluminum to separate the boards would give better distribution. But, the aluminum is so thin it would flex more than it does now. And YES, it does bend, as others have noted. Those with a less keen eye may not notice it. The bending is not an issue for me. It actually improves the light distribution, if anything. The heat buildup in the middle area is considerable. I removed the drivers and mounted them perpendicular to the board. I then bought small USB-driven Xbox fans to gently blow on the drivers to keep them and the light cooler, which was very effective. I would never buy this type of light now that bar lights are available. I only use mine in veg now, turned down to 350 watts. Even so, the plants directly underneath the light are not as happy as others in the same area. I've used a lot of mid-priced lights in my new adventure as a wannabe grower. The SF-4000 is my least favorite light. Even 2 SF-2000s are better than one of these chunks of localized light and heat. Just one user's opinion, of course. Shane's chart demonstrates what I'm saying, I think.

[@GeorgeWPush]

I'm jealous you are running bar lights as they are clearly the best. The newer version of this light has better light spread as the diodes are spread out in the middle and more dense towards the edges.

Hey Shane, i ask you because you have several high end light meters, but any chance you can do a vid comparing high end light meters with light meter apps for the samsung and appl flaghsips (s21ultra and 12promax)? would be neat to see if phone tech is good enough to give us a decent light meter at home without dropping a grand

Guys, some advice. I have a small greenhouse and I would like to increase the light available to a plant that I have inside, now that the sun here in Italy does not illuminate much. In your opinion, which wavelengths should be used in these conditions? A classic 3000k / 3500k or, as a complement, would it be better to focus on a single color, such as red at 660nm? Thanks

Gonna be tough for anything to beat the grow 300 it looks like. The Maxsisun pb4000 Pro version seems to be nearly identical to the sf4000 as far as parts and new layout. I’d be curious how it stacks vs the more expensive sf4000 unfortunately not any par tests on the pb4000 pro model I’ve been able to find, looks like great value though vs the more expensive brands. Excellent review as always thanks!

I've gotta tell you light rails or bars are so much more effective than the LED boards the boards have big hotspot in the middle. The Mars hydro SP 3000 is the best LE bowl you can get and then when you go into flour youAdd a second light. Also the LA D boards lose a lot of height and the ceiling cause a hangers take up a foot where the SP 3000 is 3"

They changed the diode layout on the new SF4000 boards to try and eliminate that giant hot spot, interesting to see how the PAR test will be on the new model.

you cant move the light up in a tent..carbon filter is in the way lol..the lab test says 18 inches.away.what does the real life test say? 315w cmh was 18 inches but people were getting bleaching and hotspots so moved them up..when you move it away the umols have gone down..and only being 315w it doesnt penetrate as much as a 600w hps.even with 3 x 315w it wont penetrate as much as the 600w hps and the 1000w de would destroy 3 x 315w..the plant is more than just the canopy.the only real life test was 3 x 315w vs 1000w de hps but the 1000w was on a light mover covering the same area.if it wasnt it would have covered less space but each bud would have been alot and better..sound if you want 20 buckets of low rate popcorn but id rather 10 buckets of bigger and better..then there is 3 x 1000w de..you have 3 points of light crossing into the next so less shadows than just using one..the lab test doesnt show any of this
