SZHLUX-2FT 80W(2x40W) Grow Light Full Spectrum with 660nm and 730nm IR

Since this is metal it gets really warm unlike my plastic LED lights. Know this so you won't put it anywhere that you will bump into it , say while watering. That works well for me since I was able to remove the heating mats that I use for seed starting. My shelves are 10" wide. With the "fins" installed the light was directed downward and only lit about half that width therefore I removed them so I could use one light per shelf. One light now covers the entire 10" shelf therefore I could use one light per shelf. Working beautifully.

I’m fairly new to starting my vegetable plants from seed. My first try with only a window was a bust resulting in scrawny, leggy plants that I couldn’t use. Last year I purchased a clip on set of two very bright glow lights and though they worked pretty well, I really wasn’t illuminating my starts evenly. Still, I learned that a good grow light is a must. This year I found these lights. I’d decided to set up on a book case in an extra bedroom, the space being roughly 35”x15”. Using only one of the two in the set, I’ve been blown away by the results. I had the lights about 14” above my seed trays and the plants were never leggy or even leaning toward the center like I’d seen before. I put it on a timer to have them on for 15 hours every day. I started my seeds the exact same date as last year, when those lights had a timer switch to run 12 hours max. Seeing how fast my plants grew this year, I probably could’ve put off starting for another 2 weeks! As my tomatoes got taller, it looked like they might be getting too much light so I cut back to 12 hours and raised the mounting shelf a few pegs and they’re doing great.The lights come with hardware to mount on chains or with clips that we used to screw onto a shelf board. The lights are very bright...not hot...but the fins help direct the light downward and the spread over the entire shelf is plenty just using the one unit. I’ll probably set up another shelf for more plants elsewhere with the extra light.I am more than thrilled with this purchase. Now that I can do so easily, I can start my spring and summer garden ahead of time, enjoying trying seeds for different hard to find varieties. This has been a total game changer.

I've toyed with LEDs for a long time and like the brightness they offer, but the costs for quality lighting have always put me off. Finally, I was informed by a friend about SZHLUX, and I thought I'd take a chance and invest $40 and I believe I've made one of the best decisions I ever have for my plants. I have a relatively small grow area and started with 250 watts about 15 years ago. Did pretty well. but added fluorescent flower bulbs and bloom boosters and grew into a minor heating problem. I then tried a 315W ceramic metal halide lamp and fought the heat for the last couple years. After receiving my pair of 40W SZHLUX 2footers, I removed all my other lights and within a week and 1/2, my plants had started to turn around and show some growth. The temp stayed right where it needed to be. My power draw went down to 80W from 315W plus fluorescent and bloom booster draws, and I'm showing 600W of equivalent light. After a short time, I became so happy with the temp, light, and plant production I immediately bought another set! I plan to add another 2footer with my flower side to give equivalent of 900W and the other equivalent 300W for my grow side. I just got my new pair of SZHLUX 2ft. 40W lights this afternoon- Easter Sunday from UPS, I couldn't believe it!

I ordered this light twice for my plants. The light itself is pretty decent, ease to the eye. However, I received the item with perfect packaging but missing parts and used appearance, bended parts.

After searching my local Home Depot, Walmart, and, hardware stores for grow lights, I found none I liked. So I opted to buy this one based on the advice of a gardening YouTuber. I’m glad I did. It was very easy to set up and it is very bright. My seedlings are thriving. The Amazon description made no mention of kelvin or lumens so I was a little skeptical and prepared to send it back, but so far my plants are germinating and I see no leggyness. However, I am prepared to change my rating and edit my description if it fails to serve my plants that will germinate later as well as the ones that I will be planting later this month.

So far, only 2 weeks using them but, the plants seem to like them. However, here's my big complaint: they only send one slave cable to connect just the two lights. This is a big problem when (as they advertised that you can link up to 4) I wanted to connect a total of two sets = 4 lights.

40 watts each and very warm for a small tent.Even with an inline exhaust fan attached to my tent, I still have to use interior fans to help exhaust the heat and move air around the fixtures to help cool them, and they're only 40 watts each!My highly rated light meter says these are nearly as low output as some of my 24 watt LED light fixtures I'm running, especially outside about a 10-degree angle.One of the lights delivered is hotter than the other three I purchased, this worries me, yet it nearly meets the advertised light intensity.I consider these LED fixtures to be overpriced and not efficient in light production, considering other offerings on the market.I just measured again, and these fixtures are not producing 184 umol... at 8 inches, as well what looks to be 10 degree LEDs emitters do not offer much light outside a 10 degree projection of light directly in front of the fixtures. This false advertising has cost me quite a bit in my garden tent design, and is making my plants suffer.Another update, these fixtures are increasing in temperature to the point they are going to bolt or kill my lettuce. They're now at 120 degrees F where they were 90 to 100 just last week.

Perfect for my tomato seedlings!
