## Description

SPIDER FARMER SF-4000 LED Grow Light 5'x5' Coverage with Samsung LM301B Diodes & MeanWell Driver Dimmable 450W Commercial Grow Lamps for Indoor Plants Full Spectrum Veg and Bloom 2.7 umol/J

Review: Absolutely great product. Quality Meanwell drivers coupled with Samsung diodes. Can move the drivers out of the tent if you wanted to to reduce heat. Quality buildand construction is great, is obvious as soon as you open the packaging. The best light for this price point, after all my research I'm really glad I chose this over a more expensive light. I thought I was only buying what I could afford, but I was actually buying something that out performed more expensive lights, as I've personally seen the difference between mine and a friend that spent double the money, with mine out performing it. This is my own personal experience.
Review: Driver went out after only 13 months, i was pissed but customer service was incredible and they sent me a new ballast which i only had to pay shipping for. The light itself is truly top of the line, sf for the win!

## 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.

## Questions & Answers

**Q: Why it s my delivery time almost a month after purchasing?**
A: Due to the COVID-19, our products are in transit for a long time. The normal delivery time has resumed now. Don't worry.If you have any questions, please contact our customer service directly

**Q: 220 conversion ? Cut the plug off ? Really ? I have a 220 line and the plug doesn’t fit !**
A: SF4000 can work in 100V-277V, no need to replace the plug and power cord, only need to buy a plug adapter, you can easily convert to 240V

**Q: Can u run these on 240?**
A: Yes you can I’ve just bought and used these adapters with the spiders. I found them on eBay:   3pc 3-Prong 110-120V to 220-240V Plug Adapter 4 Ballast Grow Light Fixture Power. They are rated for 110 up to 270v. I use a powerbox so I ended up with too many timers and found the perfect adapter

**Q: Can two of these lights fit in a 5x5 tent ?**
A: maybe, but I doubt it.   This light is overkill for 3x3, perfect for 4x4, and barely adequate for a 5x5 by itself.  If you have the money to get two of these, you can get the Spider Farmer bar lights that would be perfect for a 5x5 and cost you way less than 2 of the sf4000
