SF600 LED Grow Lights 2x4 ft Coverage Sunlike Full Spectrum Plant Growing Lamp for Indoor Plants Seeding Veg Flower Energy Saving & High Efficiency Grow Light 384 Diodes

Light weight and easy to mount/hang. Perfect for temporary indoor sunlight when bringing outdoor plants into the garage.

This is the second of these units I've gotten. My plants seem to like them & are thriving better than with the fluorescent T5s I had before. Using in unheated Costco greenhouse to grow winter salad greens, start seedlings, keep tender perennials going. So far so good!

spider farmer sf600 works great for desert rose propagation ,very bright

I happened to be in the market just as Spider Farmer's new long format SF 600 (and SF 300) came on the market. I am using 6 foot wire mesh shelving for my orchid room, and a pair of SF 600's seemed like just the thing. I received them today and set them up, and they're everything SF advertised. The units consist of an six inch wide aluminum reflector hood with two strips of LEDs affixed along the length inside. The footprint is very similar to a fluorescent fixture. A mix of 3000k, 5000k, red, and IR LEDs give off a great and even light that my phone photometer and some quick calculations say matches the product PPFD spec quite accurately. Once turned on, the light barely got warm. I have fans in the room enough to move air around, but I doubt you'd need them. My orchids sit at 12-18" for Cattleya, 30-36" for mid-light such as Oncidium, and my Phalenopsis sit with a bit of filtering at 36". Full sun loving plants will have to sit closer, and for them this light would cover no more than a row; if you want that kind of light you probably want to step up to an SF-1000 or bigger. There is no dimmer, either, so violet growers will want a low bench and a high hanging position. Unlike SF's higher end lights which use industry-leading Samsung emitters, the 300 and 600 use OSRAM LEDs. The result is a bit less efficiency, but it's still quite acceptable. The simple wire hangers are easy to set up and long enough to adjust to meet most needs, and the combo of the power brick and standard computer type power cord was generous at at least ten feet long. One of my two units had a small section of LED that buckled away from the hood; I'm not sure if that will affect heat dissipation or longevity - I have a query out to Spider Farmer to see what I should do. [Edit: Spider Farmer will back the unit and does not indicate that problems will arise from the defect; their responsiveness was good.] But other than that I think this is a fine new addition to their product line. The long format of the light will be familiar to houseplant growers and can easily replace a tube lamp with superior light as tubes wear out.

Can’t find a replacement cord but worked great for me.

Purchased last year on sale , the price is now over what their own website charges 🤣 90$ now is 109$?+ Initially, it was very bright and showed greatly improved for plant development and colors, so I was happy. after a few months, 2 red diodes failed and the LEDs started dimiing and reducing output , so I contacted their supposed 24/7 service , and even emailed them . Days+ later, I get an email replys by 2 different supports and bounced me back to a Amazon spider service member, who ask for for a video so I provided them. support said dead section are are IR , which should be visible on an IR camera(but are not ? 😅). And then told it's working fine just reduced (wut?) , if it's reduced it's not working 😂 , these don't have a controller for light level so if it's reducing means something on the circuit is failing this not working right??? The lights are cheap entry level but I didn't expect just a few months of work and support who don't even seem to know the product or how they function as they'd go off and wait for days to process replies. Prior when I've contacted this company asking about products I wanted to get specifics for use I've gotten weird replies from them and trying to push to get sponsorship or join their paid in affiliate program. When I literally just asked about light performance 🤨, honestly seems really weird behavior, but the customer support isn't one I'd recommend , nor this product specifically due to short lifespan and failure of it and support for product under warranty

Very cost effective. Bought several to replace my four-lamp F32 fluorescent industrial channel fixtures. Lower power usage, less heat, and better brighter light. Highly recommend.

Our indoor plants were drying, as soon as we installed this we saw them flourishing again. Easy to install and it looks good in our living room.

My tomato plants are averaging 2-3 inches of upper growth every day since using these grow lights. They exceeded my expectations. I had to buy extra pulley systems to raise and lower these lights as the supplied mechanism was too awkward and too short for my tomato plants. Due to their ability to grow the plants rapidly, it became a hassle adjusting the lights upward every day. I would suggest Spider Farmer use a simple light chain and S hooks system to improve the versatility but the lights themselves are fantastic. They've been running for approximately a month now, 16 hours daily with no issues. The cost of the lights was surprisingly low for their high performance!

I have both models the 600 and the 300 as you can see in the pictures. They are basically the same, just double everything. I have used their larger lights for tents and was very happy with them. When a head of lettuce hit $5.00 I figured it was time to see how their lights are for Veggies. For results I could not be happier. In one pic you can see the "spill over" light is enough to grow my potatoes and start my tomatoes. I changed setup once I realized it works and we actually use it. It's exciting to grow and eat your own food. The reason for only 4 stars is that the 1st one I ordered the power brick died the 2nd time I plugged it in and I can see a possible issue in the future because it's not the strongest connect between the plug and the light board. Think loose USB or headphone connection on your laptop - not the strongest connection and they can come loose. Now these should last as they really shouldn't be plugged and unplugged that often at all... just stating its not the most solid feeling light I've handled. That being said I went ahead and purchased the more expensive 600 version even with my own concerns. The customer service was fast with response and solutions to my previous issue and I really love their price vs performance compared to other companies. With them you also know you are getting the higher grade LEDS and Driver. I believe the pictures will show more than I can write.

Works great using it for starting seedlings

I love this grow light. It is very light weight, it produces a lot of light and it's easy to use. My garden starters did very well once i got this light.
