Used this product since I started my medical grow. Compared to other quantum boards that I’ve had. This one is an absolute beast. I only need about 60% light it gives with the dimmer for my babies then I turn it up 100 during bloom and flower because 100 during veg is TOO much. Which is a good thing. Never had any problems with the light. It is big and heavy so if you want to get I recommend you have someone to help you put it up. Don’t want to drop it ! It might seam steep if a price. But my products come out better than other products who’s tent doesn’t equip the s4000 just won’t get as much light.

After doing tons of research on this product I have found that it is absolutely the best bang for my buck. Looking forward to working with this one.

You won’t regret going with ” Spidey ” !!!… ThxMch. 🤗

great light started with one. now I have four and might buy one more depending on new set up.
Craig R billings –
I grabbed 2 sf4000s. I’m very happy with results so far. Excellent quality and performance for the buck. I would for sure recommend anyone buy these. I will be buying more.
Krzysztof p. –
I love u guys!! Led doing amazing work!!
Ruben P. –
I bought these to replace hps lights Cheaper to run less heat I thinking about buying two more
John Fry –
I love the sf4000 because it has high output with little draw at only 450 W. It outperforms my 600w HPS and runs cooler and uses less electric. My yields are great with high-quality medicine and I couldn’t be happier.
Dustin –
When I purchased this light I was using a 400w HPS and a 400W mH side by side in a 4x4x6 box i built with plywood. Had 4 seedlings going in my own soil recipe. They had been under this light for almost 4 weeks when i received my SF4000. I expected good things from this light, but was blown away after a week i had 3x the growth rate and they were ready for flower. The next flowering cycle i did i had to remove the top of my box and hang the light from the ceiling, my 4×4 was bursting at the seams. I didnt hesitate to get myself an sf2000 for my veg tent. And also built a full 8×8 room instead of the box. Recommended highly!
John Fry –
I love my sf4000. It outperforms my 600w hps and has a high output with low draw at only 450 Watts. With less electricity and lower Heat it’s an easy pick over h p s. I get high quality meds and great yields, I couldn’t be happier.
Mcnate –
I love the build of this light! One of the best in the market! Great little 450w light! Performs as well as m
A single ended 1000w MH for veg so far. And can’t beat the price anywhere. Other named brabd lighting is overpriced. It’s all made in China anyway. Just order direct. And save hundreds of bucks.

Could not be happier with the professionalism and fast service of http://www.spider-farmer.com. Originally ordered the the SF-4000 LED grow light from a 3rd party re-seller. Didnt get an order confirmation or tracking # for over a week. Cancelled the order, and bought directly from Spider Farmer. They had the light on my doorstep in 3 days. Solid packaging… Proper light.. Thank You Spider Farmer.!
Dennis Root –
I have an sf4000 and an sf2000. I love both of the lights they are great for personal at home grows. Easy on the electric bill and still produce big fat frosty buds. I have many lights from many brands but spider farmer is the only one I have bought more than one of. Best bang for your buck I believe!
skipperbug –
I had the opportunity to use the SF4000
I highly recommend this light for indoor grows
Heat was never a issue
Light coverage was everything expected
Great and easy to use
Highly recommend!!!
Cindy Brooks –
I have heard and seen nothing but amazing things about your products and this is one I have on my list to get asap. Can not wait to grow with you 💚
Steven Ingram –
This light is a beast. With this thing you can kick any grow into high gear. Perfect for 4×4 tent.
ELCHADO –
Everyone I know that uses Spider-Farmer has always stood behind their lights and how it outperformed their previous old school grow methods and they haven’t looked back since. Hoping too add a Spider-Farmer to my 3×3 very soon.
Dr_Boom –
I used the SF4000 for my last grow, with fantastic results. It was a perfect size for my 4×4, and gave ample coverage for the entire tent. My harvest was up from the last lights I used. I had one plant and harvested over 1 lb, which is fantastic because the plant was not near as big as I could have grown it. The buds were nice and tight, which is to be expected from a quality light.
This light puts off a little heat, but not much when compared to other brands. I had no heat problems at all. It was easy to assemble and hang in my grow tent, and took me less than 10 minutes from unboxing to hanging in the tent. I am very happy with this light and would recommend it to anyone that is looking for a quality light at an affordable price.
Ronald –
Who doesn’t love the sf4000? Well, I guess if you’re reading the review you don’t have it yet and can’t love it yet. Yet! Lol one of the best lights for this price point ever. My 8×5 loves these lights so much. They’re all I use in it. It’s all that’s needed really. Huge plant growth and bud production. You seriously won’t be disappointed. Well loved by the community and will be by you too!
Kootenay Grown –
I’ve been using the SF4000’S for about a year now and have seen crazy results! Tried a few lower end leds when I was trying to find aceplacement for my gavita 1000’s. Eventually came around to Spider Farmer and they are killing it in my rooms! So happy with the increased yields and rigorous growth under these SF4000’s as well as the lower power usage! More yield, 1/2 the power!
You won’t regret your decision to buy spider farmer!
Ryan –
Best qb style light
Alexander Sabino –
My last grow with the sf4000 before I used og hoods and 600watt hps. man these new lights are amazing big up to SPIDER FARMER great product super bright great results I can’t wait to get my sf7000 next week it’s gonna be on. Much love and respect to SPIDER FARMER 🙌
Proud_to_grow_loud –
This light has made me flowers that are 2x as dense and at the very least 15% bigger than before. Looking at 2 sf-4000’s making the tent feel like summer, which actually helped with VPD! Vapor pressure deficit is humidity to temperarure ratio for plants to perform at their maximum potential. My plants love it warm but not over 90 and these lights kept it around 80-85 when they were on. All I needed to do is push humidity in and I got amazing results. Most LED’s are either too hot or too cool… these are right in the center for that perfect environment! I’m an organic grower and I found there to be better results inside my tent then outside. I had very little sun light this year so Im bringing everything indoors for the winter! Thanks for the amazing lights and my flowers thank you too!
Josh –
Great light for beginners and vets works great makes them dense
Aj Brock –
This is what my grow buddy uses. It does great compared to my blurple cheaper lights, being disabled it was my only option unfortunately. We have done close to the same exact grow, major differences being the lights. No matter what I did he always seemed to have way more density then mine. I can only think it’s the light difference. I would love more then anything to grow an experience your lighting for myself in my own medicine. Definitely can see it in action first hand and it is awesomeness
Steven Ingram –
I ABSOLUTELY LOVE THIS LIGHT!!! For about a year I used the sf1000 and loved it so much I upgraded to this BEAST OF A LIGHT. The trichome production and canopy penetration are absolutely insane. This light is a must have. Highly recommend for new or novice growers. You won’t be disappointed.

Ran 1000watt hps for almost 10 years. Wanted to make the switch to led and I did plenty of research before I made a purchase. Lots of more expensive options out there, however I can’t justify dropping a grand on a light..at least not then. Through my searches and comparing one light to another..I kept coming back to spider farmer. Pulled the trigger and picked up a sf-4000 to get my feet wet. Best decision I made when it comes to illumination. Tons of quality light.. doesn’t run that warm and the spectrum is dialed in! I have another brands light together with the sf-4000 as I felt I needed a little more power in my space. Didn’t set out to do a side by side comparison..but the flower under the spider farmer is noticably bigger and resin production is superior. The quality of the build is superior also.. quality materials and fit and finish. Top notch components..put together well..at an affordable price..what’s not to like? In the future.. spider farmer will be the first light I look for.

This light has been amazing for me my last two grows and does great for an indoor grower like myself. Its very good on the energy bill and the plate the lights sits on produces the perfect amount of heat to keep my tent at the perfect temperatures needed for my plants. I love the dimmer attachment; it saves me time knowing I dont have to adjust it through the drivers. Even though the light up front is a nice chunk of green backs; its worth every penny. After doing a good amount of research and seeing some fellow growers using this light I knew it was the best product for the type of growing I do. Energy saving, great light spectrum, and makes my plants happy. If you run it for 24 or 12 hours a day you will be happy with what this light can do.
Martin Martinez –
Been a amazing product for me so far. Very easy to use and setup and everything it’s advertised to be.

I used the SF4000 for my grow, with awesome results. It was a perfect size for my 4×4, and gave plenty of coverage for the entire tent. I had 4 plants and harvested over almost 2 pounds.The buds were nice and compact which is to be expected from a quality light.
This light puts off a little heat, and use little energy. I had no heat problems at all. It was easy to assemble and had it hanging in my grow tent in less than 10 minutes from unboxing. I am very happy with this light and would recommend it to anyone that is looking for a quality light at an affordable price…very good spider farmer!!

Everybody should own one of these lights. I purchased the sf-4000 for my plants about six months ago and I can say without a doubt that this Led light optimizes it’s par ranges at every angle of my 4×4 grow tent and could easily run a 5×5 with no problems. I went from growing an average of six ounces to almost a pound a plant in a five gallon bucket. If you need a light to triple your yield at harvest, the sf4000 or any of spider farmers other lights made after That is what you need to get because I can verify that it’s bang that puts out 450 watts or more is worth every buck you save and put on it.

BigDaddyK- best LED around – have a look at my growdiaries.
Matej Heldes –
they are great!
Virginia is for growers –
Great light and a great value. Filled the 4X4 from corner to corner. Handled everything beautifully on the first run. Puts off some heat in high gear though so plan accordingly.
Rob –
Used a friend of mines blurple for few weeks prior. First time grower. Within a week I have surpassed his(my plants were noticeably smaller than his). Its as if it grows by the day noticeably. Defoliated on Monday, within four days it’s as if I didn’t. I can’t believe the difference a light makes. They’re so lush and happy now. Can’t wait to see what flowering will do. Im only at 60% brightness now in Veg. Best bang for the buck hands down. My friend is jealous by the way. I have his clones moving faster than hjm.
Wayne Schirner –
Does anyone have a PPFD map for this light without a tent? I’m planning an indoor garden using an elevated 3’x3’ bed to illustrate gardening for those with mobility issues. I’ve ordered this light and am waiting for it to arrive. I plan to grow some vegetables and herbs that don’t have a tall mature height.
Justin –
This is my go to LED for my 4×4. Just pushed out over half a pound on 1 Rocbudinc autoflower with this light. Can’t go wrong with spiderfarmer LEDs
Brett –
Great light just used in 4×4.
Buds are nice and big thc is good aswell. Great to use in summer aswell as dosent give much heat off.

Got two of these bad boys in a 4’ x 8’ tent and they do work! Worth every penny!

Hello,
I have two of these sf4000 as well as a sf2000. The sf4000 is amazing. I went from hps lights that drove up the electric bill and added unnecessary heat problems to these. They are so much better. These sf4000 lights have been an amazing replacement for my 600watt hps lights. I hope to get another in the future because I especially like the daisy chaining ability they have. That you for your great products. I will continue to use your wonderful products. Thank you
John
