2025 Spider Farmer SF4000 EVO Dimmable Full Spectrum LED Grow Light

Introducing the Samsung LM301H EVO LEDs. Boasting an impressive efficiency rating of 3.14 µmol/J PPE per diode , these LEDs outshine even the renowned LM301B, LM301H, and Bridgelux 3030 chips in terms of sheer effectiveness. Representing the pinnacle of horticulture lighting technology, they radiate unparalleled brilliance while operating at heightened efficiency levels.

Surpassing the capabilities of both the Samsung LM301H and LM301B LEDs, these EVO LEDs redefine plant growth enhancement. With superior light quality and an increased light output per LED, they harness a more potent blue spectrum, all while achieving a level of efficiency unattainable by non-EVO LEDs. Veg footprint is 5 x 5 ft, Flowering footprint is 4 x 4 ft.

With these lights, you'll get the best growth rates possible while saving energy. You can only run them at 450 watts—which is half as much as HPS or Blurple lamps—and still achieve 50% more harvest than those systems. The veg footprint is 5 x 5 ft and the flowering footprint is 4 x 4 ft. The SF4000 has an upgraded SF series, with a dimming knob and light switch. This allows the user to adjust the light intensity at will – crucial when growing plants indoors or commercially.

Whether you're a pro or a beginner, the SF4000 is an excellent choice.

Spider light

My plants just love this light.After three weeks I cranked it up to 400 Watts. No burning.Buds are looking good

Great light!!

Perfect light for what I need and it was delivered in a few days I was shocked thank you so much again Trimleaf 👍👍

Lights that grow FIRE hemp, absolutely the best light I’ve ever used thanks for your exemplary se...

I’ve used many different types of lights, none can match this Spider 4000 dimmable, my plants are growing right out of their shorts!!!!

Spider Farmer SF4000

Its an impressive light to say the least. Easily hits 4x4 footprint. 5x5 is a bit of a stretch. I don't use a tent but where this hangs I was able to remove 4 other single board 150w lights from another brand. So a lot less heat! Less running the AC! All around great investment. You can't go wrong with Spider Farmer.

Love this grow light glad I bought it best bang for your buck
