SZHLUX LED Grow Light 4ft 140W (2×70W, 800W Equivalent) for Indoor Plants, Super Bright Full Spectrum Sunlight Plant Light, LED Grow Light Strips, Linkable Growing Light Fixture - 2 Pack

Using them on the end of a coolgrows 2-1 grow tent. Just wish there was a dimmer addon. For when using for seedlings. Nice for herbs like basil and cilantro. Have to keep them high off the plant, cause they tend to make the basil flower. They put out a little heat too. Since I use them in a basement a little heat is welcome. Using a fan, I assume will help keep it cool in the summer. So far so good. If I have any issues or revelations I will update.Grow tasty food!Update: April 2022. I have to say these lights put out hardly any heat. My earlier assesment was wrong. I really like these lights. Bright and really make my young dahlias grow well. Getting them ready for the garden. Have over 50 plants under them.Next will be seedling tomatoes.Update; May 2022. I got one light temporarily standing on end. Lighting over 50 dahlias of different varieties on shelves in the shower. They are growing so fast. Some almost an inch a day. Not spindly at all.Update; June 2024. I also have purchased the 2ft lights. Just as great with no problem. Now, present day, I just purchased another set of the 4ft lights. My third purchase. Here is the issue. Was supposed to be in repackaged amazon box. That alone made me wait an extra week for delivery. When they arrived the lights came in the original box with a ripped hole. Missing most the mounting hardware. No booklet. Missing wire. Also I wonder if this was a return since there was no protective plastic on the light lens. Because the lights work and due to extra parts from my last two purchases I will keep them. But... Now I will rethink any future purchases from this company. Also, I am now not prone to recommend this item to a friend.

Good shipping time. I was Leary first. B cuz you know... Budget stuff. This wasn't really budget tho. If you use a grow tent, this thing will reign! I don't an I'm not professional with lights. I put these on a 3 foot window / outside type grow thing in a back room for cannabis grow in veg so far. I'm impressed w this! The lights werk very good! They shot up like fire to 3 ft tall and branching in a matter of several days w 8 hr intervals! The kit comes 2 light rails and easy peezy assembly. A 8 yr old could do it. Comes w everything you need! Try one people I don't think you'll be disappointed! They're good for beginner or seasoned grower. If you want high quality buy high quality. I didn't see any reason to . Too much hyped up tent growers! Unless you absolutely have to be! Try it!

Pretty bright for the price. 4 feet long and stretches the full length of my tent providing even light for plants. They give off almost no heat, and they're super lightweight. For the price, I'd recommend these lights.

I puchased 12 lights to use in a NFT hydroponic system (4 level system). 2 lights for backup. The manufacturer packaging was adequate and contained the electronic connectors, hanging hardware, reflectors, lights and instruction book. Amazon shipped the original package in their own larger box twice but sent 3 boxes in the original package/box. So, the hanging hardware and connectors are simple but function well. I super-glued the clips to the lights to make sure they are secure. Right out of the box, one light didn't work and two others flickered in the led panel. For one light, after a couple of minutes the flickering stopped. The assembly procedure was easy except for the reflectors because there is a tiny slot at each end where the reflector fits and, let's be honest you need to have patience to align it. Okay that was harder than it should have been. But, once I got the hang of it, assembling the reflectors was easy. I connected 8 lights in series without a problem but then read later that only 4 should be connected in series. Now, I have 2 sets of 4 lights connected in series. I purchased the lights in April, 22 and set them up in May, 22. I run them on a 'long day' cycle, ie. 16 hour days, for the last 4 months (today is Aug. 5th, 2022). I don't find the lights hot as I have read in other reviews. They are warm but not 'hot'. I hung them between 14 in. to 19 in. above the plants (lettuce/cucumbers/green peppers/cilantro/green beans/onions). I measured the PPFD at that distance. Here's the PPFD measurements using my phone app, (Photone): center: 538 umol/m2/s, out to 8in from 'center', 310 umol/m2/s. The recommended PPFD to grow lettuce is around 300 umol/m2/s so these lights are more than adequate. They are performing well for my lettuces, cilantro, arugula, as well as my 'fruiting' plants: cucumbers, onions, green peppers and green beans. I didn't expect to see fruiting plants produce anything because they are simply 40watt lights but surprise, cucumbers are coming like crazy and green beans and green peppers are growing great! I've had 2 harvests of over 200 lettuce plants in the last 4 months... yeah thats alot because the thought was to sell at a farmer's market. I need more experience before that happens but I expect to grow thru the winter with these lights. They get the job done and don't break your wallet. Greg

I like that the lights are Bright, and the plants love them!

When looking for products, I alway look for USA. That is why I purchased these LEDs! They advertise made in the USA but they are not! They are made in China.Amazon Product details were...Item model number ‏ : ‎ SZ-2T70Manufacturer ‏ : ‎ SZHLUXCountry of Origin ‏ : ‎ USAAs for the lights, I had some trouble with the spring clips that fasten to the top to hold the light up. I had to bend them closer to make them tighter. Seemed to slip off the light real easy.The lights don't have much red, orange or yellow, but I will say that they are brighter than my others.They also came with no directions, but they were similar to my others. (Simply warning others.)End result, they worked. I just was excited to buy USA and disappointed when I saw the box. Pic attached.

Bought used like new neither light worked . Bought second set new and very happy with this set.
