Spider FarmerSF4000, Samsung LM301H EVO Led Grow Light, Full Spectrum Plant Lights, 450W Dimmable & High Efficiency & Deeper Penetration Commercial Lamps for Seedling Veg & Bloom in 4x4 Grow Tent

Great LED’s, fantastic efficiency. Rugged as hell and has effortlessly trucked through humidity, gnats, dust, debris, storage, and shipping multiple times. Still runs like a champ over 3 years later. Super nice for keeping plants and cactus going over the winter; it’s so good at passively dissipating heat that it noticeably warms up whatever room you’re in.Even my dog doesn’t know the difference between these lights and sunlight. Recently bought another one to use for starters. Worth every penny.

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.

Why did you pick this product vs others?:Heard this led light was the top of the line and would work for my growing needs love it so far Lighting quality:The light quality is great and the ppfd is exactly as described

As you see these plants are from use the spider farmer led grow lamp. Works great . I have used two grow seasons and a few times to start seedlings…. Great for 3x3 grow tent and perfect coverage. Easy to assemble right out of box. Great quality.

I would just like to say Wow! Spider Farmer 2000 SERIES is the real deal. I have completely changed out my grow room with all Spider Farmer SERIES LEDs. Spider Farmer SERIES 2000 is a true full spectrum led grow light. There's nothing cheap about this light. The FOOTPRINT of Par is very remarkable. Spider Farmer will be a True hero for the beginner or the professional grower. Spider Farmer SERIES LEDs are also affordable for the beginner or pro. I have done every Test from par testing, heat source testing, DRIVER dependability, MEANWELL DIMMABLE POWER BLOCK. SAMSUNG'S LATEST LED CHIPS, QUANTUM BOARD, AND POWER DRAW WATTAGE FROM THE WALL IS ONLY A LITTLE OVER 200 WATTS, VERY LOW POWER CONSUMPTION. I WILL BE DOING A FULL VIDEO REVIEW ON YOUTUBE DEMONSTRATING HOW WELL THE SPIDER FARMER 2000 SERIES PERFORMANCE REALLY IS. ALSO I AM DOING THIS NEW VIDEO WITHOUT ANY PROMOTIONAL ADVICE FROM THE COMPANY. I WANT TO MAKE SURE THAT OTHER GROWERS SEE FOR THEMSELVES HOW GOOD THIS SPIDER FARMER SERIES REALLY IS. IN MY OPINION I WOULD BUY THIS LIGHT OVER THE TOP BRANDS OUT THERE ON THE MARKET. THE OLD SAYING IS YOU GET WHAT YOU PAY FOR AND MY OPINION IS DON'T GO OUT AND BUY A 1000 DOLLAR LIGHT THINKING THAT YOU HAVE THE BEST LIGHTING JUST BECAUSE YOUR LIGHT COST MORE YOUR WRONG! SPIDER FARMER SERIES ARE NOT CHEAP KNOCK OFFS. THE SPIDER FARMER SERIES LEDS ARE VERY WELL MADE AND ARE PRICED AT A PRICE THAT I THINK IS WORTH EVERY PENNY. THERE NOT CHEAP BUT NOT PRICED AS MUCH AS THE BIG COMPETITORS. I FEEL THAT THE SPIDER FARMER SERIES WILL BE A GOOD DEPENDABLE LIGHT. I HOPE THAT YOU TAKE A GOOD LOOK AT THE SPIDER FARMER SERIES GROW LIGHTING, YOU WILL FIND THAT EVERYTHING THAT I TESTED WAS SPOT ON. ALL I CAN SAY IS JUST BECAUSE YOU PURCHASED A GROW LIGHT THAT COST MORE DEFINITELY DOESN'T MEAN THAT IT'S BETTER, A FULL TEST WILL PROVE HOW WELL THE SPIDER FARMER SERIES REALLY IS. I HOPE THAT THIS RIGHT UP HELPS OTHERS. AND LOOK FOR MY FULL REVIEW ON YOUTUBE. IN ABOUT A WEEK. THANKS AND HAVE A WONDERFUL DAY.
