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

My sf4000 is 450watts. I get 500grams every run, even when dimmed to 380watts this light is beast lol

Thank you always for light reviews, appreciate

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. ✌️

Awesome video man like always! Could we get a updated list of the best lights please and thank you!!!!

I'd worry those two drivers would be too heavy and lead to bowing over time. Thanks for another great vid tho.

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

Are you alright man? you seem pretty depressed here

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

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!

Shane, please do a yearly or every 6 month top gear style leaderboard or at the end of the video to give a Shane rate just for a comparison

just an idea

[modernhorticulture]

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

[waylonbeasley]

If you're going to spend that much on a light like this one go ahead purchase a bar style. Much better spread and 0 hot spots.

[shamelbennett]

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

[chiefy]

Alright Shane I love your YouTube vids very informative 😁👍🏼 are you going to test the SF4000 2021 model? The leds are more condensed to the corners

[jawnhuh]

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

[timpage]

Gotta thank Spiderfarmer aka Mehezi Viparspectra and Mars building great lights that helped bring down the previously overpriced asks from manufacturers. I tell people what I paid for my old HLG rspec a few years back.they can't belive it. Over 2$ a watt then.

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.
