SF2000, Samsung LM301H EVO Led Grow Light, Full Spectrum Plant Grow Light, 200W Dimmable & High Efficiency & Deeper Penetration Lamps for Seed Starting Vegetables Bloom in 2x4 Grow Tent

The dimmer is a great feature, I'm running on 40 percent so there is so much room if I need more or less light! Covers a decent amount of area, absolutely zero noise, and very easy to use! Super happy with this! Important to note that it is extremely bright, and hurts to directly look at even on only 40 percent, so be mindful where you plan to put this!

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.

Really happy with purchase! Fast delivery and very well packaged, sturdy foam and cardboard kept it safe even with rough delivery from delivery guy. We are really impressed with the light, very easy to use, comes with everything you need to hang it etc. Really looking forward to getting good use out if this. Also really happy with the wattage and the positive result it will have on our power bill! I would definitely recommend and would happily buy again .

I bought this to keep my tropical plants happy this winter and also one or two hanging plants. Well, the results are astounding so far. All of my plants are thriving and those that had already lost all of their leaves for winter have now come back to life with new growth and are flowering. It's 20 degrees here this morning or I would go out and make a video, but when it warms up, I will try and post it.

Great lights for indoor gardening. The light intensity and spectrum promote healthy growth and plants are thriving. Light stays cool, dimmer functionality is a nice feature. Super light weight, build quality is very good, and very pleased with performance. Would definitely recommend. The customer service from Spider Farmer is second to none!
