Spider farmer SF 4000 Official description
Low operating cost and high power: SPIDER FARMER LED plant growth lamp adopts the latest high-performance LED technology: Samsung LM301B diode, high energy efficiency of 2.7 umol / J, provides strong light power and uniform penetration of the canopy, achieving the highest maximum performance. It consumes only 450w and has 50% less operating power than HPS or other SMD LEDs or Blurple lamps. Vegetable coverage is 6 x 6 feet and bloom coverage is 5 x 5 feet.
New Diode Placement and Dimming Design – Improved SF4000 adds light. The location of the diodes gathered at the edges makes the PPFD more uniform and the dimmer knob gives you the freedom to adjust the intensity of the light. Useful for connecting multiple lights, unified dimming, especially in large indoor areas and commercial plantations.
Suitable for all growth stages: Excellent full spectrum: white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm). The 3000K diode provides more red light and the 5000K provides more blue light. 660nm red and infrared light is especially helpful during flowering, which can reduce flowering time and increase yield. Make your seeds your own supply. In addition, the light appears so natural that it helps to precisely control the health of the plant.
Sturdy and well-made construction – no fans or noise. MEAN WELL high performance safety conductor, generally waterproof. The updated aluminum plate is thick and sturdy, doesn’t dissipate a lot of heat, has a high-quality cable protection jacket, and is an easy-to-use packaging. High-quality components mean your lights will last longer, but they can also save you money.
Buyer evaluation
RWG111:
If you are looking for a good quantum board at a fair price, the SF4000 is more than just a bill. This light is impressive right out of the box. It is very well packaged and has everything you need to qualify for work. Made in red and blue for bloom, the bright, full-spectrum white light is not blurry. Great light for indoor gardeners. I am very pleased with this light and will be chasing the SF2000 in the near future.

Jay Puckett:
This is my second sci-fi-4000, I am playing around with plant genetics a bit, these lights are just like the seller said! It is so well done that it completely covers the 5×5 area as mentioned above. Excellent heat dispersion.
My plant loves this light, the harvest is bigger. If you have controlled growth and want to get it right, these are the lights for you!
If you have any questions about why this light works and how it works, please feel free to contact me. The question appears to have an incorrect answer due to lack of research.

Tyson Amy:
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.
