Review: The Hype is Real - If you have been in the indoor growing community for any length of time, you have likely heard these lights recommended as the gold standard for budget-friendly setups. After 8 to 9 years of indoor growing and testing countless different light fixtures, I can confidently say that the rumors are entirely true. These are, by far, the best budget lights on the market. Here is a breakdown of how they perform in a real setup and why they have earned a permanent spot on my racks. Coverage & Growth Performance I run a standard setup with 4-foot-long shelves, and I position just one light per shelf, right down the center. The Results: Incredible. My microgreen grows have never looked so vibrant, healthy, and lush. Light Output: The light quality is more than adequate for high-density growing, providing the exact spectrum needed to prevent leggy crops and maximize flavor and yield. Smart Home Integration (Vivosun Compatibility) For those running a smart grow setup, these integrate beautifully. I pair mine with the Vivosun Smart Plug, which allows me to automate my lighting schedules through app "recipes." Note: Because these are standard plug-and-play lights, you won’t get advanced features like automatic sunrise/sunset dimming, but for microgreens, you really don’t need them anyway. Simple on/off automation works perfectly. In fact, any other timer would likely work, but I have only tested with the Viviosun smart plug. Build Quality & Unboxing Packaging: The lights arrived very well packaged, ensuring no damaged bulbs or bent fixtures during transit. Hardware: They include a generous amount of mounting hardware, making installation a breeze regardless of your shelf type. Materials: The build feels durable and high-quality, not flimsy like other budget options in this price range. Pros & Cons Pros: Exceptional value; proven track record for microgreens; robust mounting hardware included; works seamlessly with Vivosun smart plugs for scheduling. Cons: No native dimming features (though entirely unnecessary for this application). Final Verdict If you want fantastic, vibrant food without breaking the bank on commercial-grade fixtures, this is the way to go. They offer quality materials, excellent light output, and unmatched value. Highly recommended!
Review: Good grow light, many setup options - I got the pinkish colour grow lights as I’m just using for seedling starts, having done more research I probably should have gotten the full spectrum full white. But they are still working good for me. 6 lights and lots of cables and plugs so you can set these lights up anyway you like. I have some indoors and some in my outdoor greenhouse. Seedlings do good compared to what I had before but don’t put too close as they will burn your plants. 10”-12” min I find. Just like the mention in their pictures. They do give off enough heat to keep greenhouse warmer when the weather was a bit cooler so that’s nice. Maybe add 5C more in temp. They are NOT rated for outdoors or humid conditions but so far I’ve had no issues in my outdoor greenhouse with the humidity. But time will tell I guess. They seam well built for what you get, all aluminum side reflectors and lights are covered in a thin plastic that should hold up well. When first putting everything together they left a strange smell on my hands for a couple days so I wore gloves after that. Probably just residue from the metal but I wasn’t expecting that. All in all I’m happy with the lights and the cost at the time, they should serve me for many years since I only use once a year in the spring for seed starts.

## Questions & Answers

**Q: Are these led lights dimmable?**
A: The cords have an on/off rocker switch built in.  Generally this style of LED is not dimmable.  Each is individually not that powerful.  I am adjusting the intensity by adding and subtracting tubes and adjusting the height over the plants.  It is working out fairly well.  For an 18" x 48" shelf I am using 3 tubes.  I just used these this season for seed starting and those plants were just put in the garden.  They worked well.

**Q: How many lights and what distance for sowing seeds for 48"x24" flats?**
A: We do not use them for seed flats at this time but will likely do so next spring,  These are very bright, powerful lights.  I would use no more than two 48 inch per flat.  Not knowing your location or setup I do not think that these bulbs will generate enough heat without other supplemental heat.

**Q: How far apart in parallel should the lights be placed for growing seedlings?**
A: The height would also need to be considered as for spacing in parallel.  12 to18 inch for approx 12 in height

**Q: I bought a six pack of 2' lights. the shelf is 16" x 36". How many 2 foot lights per shelf?**
A: I turned my walk in closet into a nursery. I have 3 long shelves around 4’ in length and 2.5’ in depth. I use 2 lights per shelve. That’s been working for me.
