Barrina T8 LED Grow Light 4FT,168W(4 x 42W), 1000W Equivalent, Full Spectrum, V-Shape with Reflector Combo, Grow Lights for Indoor Plants, Greenhouse, 4-Pack

Light output is nice, installing shades is simple. 3 of 4 had the clear plastic fall of their tracks and slip on the tracks that hold the shades, which impeded the shades from sliding on. A phillips head screwdriver and 15 minutes solved that, but keep that in mind when you buy, you might have to pop off the ends and fix the track. They seems to pop off easily, but it's not an issue once the shades are on. These will just barely fit in my 48" tent, and it presses against the sides a bit. If you have a more rigid tent or hard sided enclosure, it might not fit. Been running for almost 3 months, 12 hours a day, with no issues. Inside of the tent gets to about 25C, ambient around 20C so they're not super hot. The extra bits to connect them end to end is a nice touch, even if not needed right now. It only has 2 plug cords however. Not a big deal since they're all on or off, but if you wanted to turn them on/off separately, you'll have to do 2+2, or 3+1. Overall, good product. Happy with output and performance, especially at this price. The lemons and herbs love it, and the seedlings are growing nicely.

If you want the quick answer, these lights are great and met all my expectations. With that said, I am not a scientist. I have not measured the lumens, color intensity or anything else. I am a simple man. Weather this spring has been very strange. My potted plants needed some sunlight and the weather was just not behaving. So I purchased this product. NOW, I was intending on buying a different light, but saw in a review that they liked the Barrina lights better and I think were talking about something functional about the light that I didn't have the tools or practical experience with. Therefore I purchased the Barrina LED set of 4 for a few dollars more. INSTALLATION There are a few installation configurations (flush mount, hanging mount and adhesive) which are all provided with the packaging. I didn't use the flush mount mount or adhesive, because I was looking to suspend the light down towards the plant. I needed hanging mount for my configuration and after measuring 6" from both ends, the clamp just clamped in place. Good sure feeling when it was together. They also included several tie wraps that are long enough to suspend the light from its mounting location if you want. In both of my configurations, I had a 2x4 that the unit was going to hang from. I measured things it out, installed the hooks on the 2x4 then hung or suspended the 2x4 in place. Finally, I used the tie wraps to connect the light to the hooks. A great thing about this unit is that it is light weight. I recognized this from the front (of course), yet with the first two lights, I mounted them to the 10ft 2x4 before suspending the 2x4. It worked well, but when I got to the second set, I just mounted them with the tie wraps. If I would have done this with the first mounts, it would definitely would have been easier. Talking about 2 sets of lights, two sets of cables that you plug in to the wall outlet and a cable that would allow you to have all the lights in parallel. So this allows you configure two different light configurations. The plug end has a switch so you can turn the light off using that switch. BRIGHTNESS I was sitting in my garage, calming from a busy day, watching a show on the first night. It was the last day of April and I tend not having clocks around. Hey, I'm retired; lived with clocks all my life...why be on the clock when I retire. I was starting to feel a bit tired, but the sun was still bright out. Man, I must have really worked hard today...then I noticed that through the window, it was full night, but the lights were on so it looked like daylight. For me, that was a good indicator that there is enough light coming from this. VALUE FOR THE MONEY I searched big-box stores and plenty on Amazon for lights. Grow lights are more expensive than conventional lighting and LED lights are more expensive than fluorescent lights. Also, this world has gone a bit crazy with higher costs, so any videos or articles that you might encounter that says a price, the price is likely higher now. But using simple math (with unrealistic numbers), showed me that I was money ahead with this configuration than trying to put something together on my own. AND, I personally really really hate the buzzing noise of fluorescent lights...it's like finger nails on a blackboard.... So this was a really good deal. Then add in that all the mounting was provided in the packaging. Its a good deal. So the manufacture deserves a solid 5 stars.

I purchased two sets of these and use them to for all my spring starts (bok choy, spinach, tomatoes, peppers, eggplants, flowers, and more). Have used them for two years now. I hang four of the lights spaced about 4 inches aparts and about 8 to 12 inches above the plants. Put it on a timer on for 14 hrs a day. Plants don't grow leggy. Great success! These are not super heavy duty like the expensive ones you can get from Johnny's Seeds. I wouldn't use these if i were running a farm. But, they are good for the hobby grower. The price and quality are both there so far.

I was concerned that these wouldn’t be bright enough to prevent leggy seedlings like you get from comparably priced ‘shop lights’. The color on these is good (not the hideous burple). Yesterday, my chamomile actually started flowering! These are actual grow lights, imagine my shock (the manufacturer was not lying!). Compared to my CMH lights, well it’s not comparable but if you keep these lights about 4 to 6 inches from your seedlings as soon as they sprout, you can program your plants to grow strong and stocky, especially if you also add an oscillating fan to lightly move the plants and stimulate them as they grow. Very satisfied with the early results. Can’t speak to durability, but I like the system and it’s dead simple to daisy-chain these lights. These lamps are grounded and come with a grounded plug. On 2 by 4 foot shelving, I thought I could get away with two lights per shelf, but I think I need three lights per shelf to get more even lighting (I just ordered more of these today). I like the reflectors and these are easy to install. Overall, these seem to be good grow lights.

After over a week, the first set of grow lights never arrived. Tracking just seemed to stall. ended up ordering a second set. They arrived after only 4 days. Nice lights. Well made super bright. Plants are doing really well.
