Features

  • LOWER RUNNING COSTS & HIGHER-QUALITY YIELDS: SPIDER FARMER LED Grow Lights utilize the latest in high yielding LEDs technology today-Samsung LM301B diodes, high Energy Efficiency with 2.7 umol/J, delivers a powerful light output and uniform canopy penetration to resulting maximum higher yields. It only consumes 450W, running 50% less power than the HPS or other SMD LEDs or Blurple lamps. Veg coverage is 5 x 5 ft, Flowering coverage is 4 x4 ft.
  • NEW DIODE LAYOUT & DIMMING DESIGN: SF4000 growing lights. More light beads at the edges, fewer in the middle. Helping get more uniform PPFD. Plants absorb light better & product higher yields. Dimming knob is adjusted the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large indoor growing and commercial planting areas.
  • IDEAL FOR ALL GROWTH STAGES: Excellent full spectrum- white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm). 3000K diodes provide more reddish light and the 5000K provides more blueish. The 660nm red and IR light is especially useful during bloom when it speeds up flowering time and boosts yields. Turn your seeds into your own supply.

    • Great Light for about 1 year: UPDATE 10/15/21
Size: 2x4
I have purchased 2 of these SF2K's . I bought the second light not long after the first, because INITIALLY these lights hold their own so to speak. The only issue, and hence why the 3 stars is, after about 1 year, the dimmer switch goes out. The light will flicker if it is used. Both of my lights still work on full power, but now I have no way to dim them and will have to purchase another light for my lower power needs. Very disappointing, but thankfully the second light's switch went out RIGHT, before I purchased a 3rd. UPDATE 10/8: A few days after leaving a review of the 2 SF2K's I purchased, Spider Farmer customer service reaches out to me. They were extremely courteous and helpful. After sending them a video of my issues, they offered to either fix them or send the appropriate parts for me to repair it myself. After watching the 2 repair videos they sent, I decided to accept the repair parts, as the repair looks really basic and simple. No special tools required or anything to that effect. That said, I've added a star to my previous rating. If these new parts last, I will surely raise my rating to 5 stars, as these lights are amazing when functioning properly. The brightness and spectrum are amazing and well worth the price imo. They produce very little heat, and the energy they consume are almost undetectable. Most importantly, I feel confident in their customer service at this point and will most likely purchase their SF4K. Update 10/15: Because of Spider Farmers most excellent customer service, not only have I added the 5th star, but I will most certainly be buying myself the SF4000 for Christmas. It's nice knowing your money is well spent. I think all initial purchases are a gamble, but Spider Farmer, I can honestly say, is a safe bet! Not to mention, these lights are POWERFUL. To the extent, you have to be sure not to blast your plants with TOO much lights. Use as directed and adjust accordingly. ... show more

    • Let There Be Light: My Spider Farmer SF4000 Plant Growth Adventure!
Size: 4x4
Title: Let There Be Light: My Spider Farmer SF4000 Plant Growth Adventure! So, I took the plunge and got myself the Spider Farmer SF4000 plant growth light, and boy, am I glad I did! Let me tell you, this thing is a game-changer, both in terms of how it performs and the awesome customer service that comes with it. First off, let's talk about its performance. This light is like a superhero for your plants, with its killer spectrum and crazy-efficient light output. Since I plugged it in, my plants have been living their best lives—greener, lusher, and flowering like there's no tomorrow. And with its wide coverage, every leaf gets its fair share of the spotlight, leading to some seriously impressive growth. It's not just good; it's freakin' fantastic! But wait, there's more! Shoutout to the Spider Farmer customer service team—they're the real MVPs. When I had questions about the product, they were on it like a plant on sunlight. Quick responses, helpful advice, and they even threw in some detailed installation guides to make sure I got everything set up right. Talk about going above and beyond! So, yeah, the Spider Farmer SF4000 plant growth light? It's a winner in my book. If you're after some serious plant magic and a hassle-free shopping experience, do yourself a favor and snag one of these bad boys. Trust me, you won't regret it! ... show more

The media could not be loaded. I own both models: SF1000 and SF2000. The light has a simple, polished design. No need to assemble. The aluminum board is thick and sturdy. It gets hot to the touch, but its much cooler than other techs. Rubbery coating reduces risk from splashes. The driver is solidly fixed in place, resulting in a solid unit. No power is wasted on fans or inefficient drivers. And the Samsung diodes offer a high efficacy rating of 2.7 umol/J. I like the blend of LED colors. Some quantum boards only have a single color for all diodes. Compared to them, this LED has a more complete spectrum. USAGE: The rectangular shape produces a different light distribution pattern. I estimate the light will evenly cover a 48" x 34" area at a distance of 27”. This would be excellent for low-light or vege plants. For mature, high-light vege / bloom plantings: 43" x 28" at a distance of 24”. For very high-light BLOOM / BUD (medicinal) end stage growth: 36" x 20" at a distance of 18”. See my PPFD chart for the numbers. And see my YT video for more measurements! The 202w SF2000 could replace a 400w HID. Magnetic vs electronic ballasts vs doubled ended HPS systems all have different rates of efficiency. So it depends on the type of HID and its specs. I've recently compared this light to a brand name Quantum Board by HLG. Two of these SF-2000s would produce almost the same amount of light for HUNDREDS of dollars less. Or you could even buy THREE of these for that much money and your light output would greatly exceed the HLG unit. DIMMING: There's confusion about the dimming options for this light. Some sources claim the SF2000 cannot be dimmed. It has a 240 watt driver that is already underdriven from the factory. Well, I was able to dim mine with no apparent issues. I took it all the way down to 50 watts. And then I decided to lock it in at 75 watts to vastly outperform a 4 bulb, 2 foot T5 fluorescent system. You MUST have a wattage meter to do this. And you should NOT raise the wattage above factory settings! This light is a huge a step above DIY set ups. The Spider Farmer LEDs are better than many other quantum LEDs sold on Amazon. Three year warranty sounds great. Seller includes contact info to get in touch as needed. But hopefully I won't need to! CONS: Because there's no external switch, the dimming option is not convenient for frequent on-the-fly changes. ... show more

After realizing I needed more lighting for my grow space, I looked up the best lighting options for a 5x5 area. That's when I found the Spiderfarm4000. The light was affordable and offered a whopping 450w of LED lighting across my canopy. The light was simple to set up, perfect shape for the area I needed to to cover and just the right size. It comes with adjustable hangers that are simple to use and are made very durable. I would strongly suggest anyone looking for a new LED light with a lot of power to buy this product. ... show more
