Barrina T8 LED Shop Lights 4FT, 40W 5500LM 6500K, High Output Tube, 6 Packs

These LED lights came packaged very well and arrived on time. The quality of the wiring made it easy to install separately or connected together and were really bright in my garage. I highly recommend these lights and if I need more for another project, for the current price they are offered at I really think you get your money’s worth

I just installed 9 of these 8' 6500k lights in my garage using WAGO 221 connectors and some 14awg speaker cable, though you could use 16 gauge. They're insanely bright and the color is perfect. It's better than daylight by a lot. I plan to add more now. Just get a laser that can make a vertical line so you can light up all of the clips for an easy install. Spacing isn't very important, really. Using WAGO connectors makes the wiring too easy. No issues with the lights. Very nice lights for the money. I'm adding an occupancy sensor switch so they turn on and off automatically. Just wire your switch inline with the hot side so it cuts the power feed to the lights, then run power out of the switch to the lights and finish it off at the neutral wire for a proper loop. No need for a ground, though it does include that option in the wiring if you're that paranoid.

I have a recessed ceiling in my kitchen with diffusers over the recess and the fluorescent ballasts and tubes were constantly flickering or not coming on. I decided to make the switch to LED's and cannot be happier with these. These are the ones with the special RF (radio frequency) circuit that won't interfere with garage door openers or wifi routers. Installation is super easy, mainly because the units are very light (they don't have that heavy ballast like fluorescents) - screw two clips to the ceiling or under a cabinet, slide the reflectors on the units and the unit snaps up into the clips. To link them, there are short connecting cables to daisy chain a number of units together. These LED's are BRIGHT! My kitchen is now a well lit preparation center for cooking. So how well did I like them? Well enough to replace the fluorescents in our utility room, out in my woodshop, and out in my garage. Gone are the ballasts and fluorescent bulbs, now replaced with energy efficient and bright LED's.

These lights are pretty good for the price and having six of them works pretty well as I'm going to use these lights to install into a Tuff Shed and I need all the brightness I can get. The testing of these lights with other lights is all about how hot they get because they're going to be attached to the joist in the Tuff Shed, a wood joist. These lights work pretty well as they give off barely any heat, which would work well for me and I burned down my shed. The product packaging was exceptional with more lines and cables and wires I would ever need to use.

My son and I own two dozen of these strip lights. They produce plenty of light, and some have worked reliably for several years. I deducted one star because the lights in one package arrived bent. The bends did not significantly affect my installation, so I chose not to wait for replacements.

I'll preface this by saying that this is my first time ever growing indoors. I've picked up on a lot of things through YouTube and websites and one of the first things I learned was needing lights that were 5000 lumens and 6500k. I've never had lights that bright before, but to be honest I thought these lights would be a little bit brighter when I first turned them on. Not that they aren't very bright already, I was just expecting something different. That being said, these are very easy to install as lights to hang from shelves. They include the screws needed to attach a chain (I grabbed a 20' cheap, black chain for hanging pots from Walmart and used pliers to separate the chain into even sections for attaching to the lights on both sides), but you'll need some hooks for the shelves to hang the lights from (again, Walmart has cheap packs of hooks for this). Using chains allows me to raise and lower the lights as the plants grow. The lights have reflectors that slide into the sides of them. These are okay, but I wish they allowed for more directional control. Their default position too narrowly focuses the light, so I ended removed some of them. Connecting the lights is a breeze. They include several cords, wires, and caps to give you some variety in how you want to set them up. You can either plug them all in directly, or daisy chain them together and use one plug. I also have them set up in a surge protector that connects to an outlet timer. This has worked flawlessly over 4 weeks, so far. Right now, I have three shelves set up, with each having two lights. This seems to have worked well so far. I feel like the coverage should be slightly better, though, so I may pick up another pack of 6 lights and have three per shelf, plus finish the last shelf with lights. One light is definitely not enough per shelf. Even with two lights you'll find that the plants on the outer edges tend to lean sightly inward towards the light source. I do not believe four lights per shelf is necessary, like you'll commonly see in growing videos, at least not for T8 size bulbs like these. As for the results, I have had my seedlings under these lights for almost four weeks. Obviously germination rates depends on your seeds, but I had some sprouting quicker than expected and growing to a healthy size in a fairly short amount of time. I don't have any experience with actual grow lights, but my experience has been great with these at a much more cost effective price point for growing my seedlings.

I’ve purchased multiple sets of these thru the years and have friends who’ve ordered after seeing their brightness. They do however start to fail after about 5k hours of use. The diodes start to blink and eventually go dark. I do use these for my on site work shop of six 10x10 pop up tents outdoors and they run day into night and it’s just shocking how they light everything up. So under typical use they may achieve 10k hours of runtime. My situation is a little extreme. You will 100% be stoked with these in any application where you need bright linkable lights!

When I first got them and installed them I was very surprised at how bright they were. Very simple installation. All my friends wanted them for their garage. Almost 2 years passed and the started going out. 2 in total. I remembered the warranty so I decided to reach out. I told customer support about the issue that a total of 2 light went out. They wanted to refund me $30. When I looked 1 (only 1) was $32 so that didnt make sense. I reached out again to let them know that i would like for them to send 2 replacements. They “did”. One arrived. I then asked for the tracking of the second one and they sent a totally different tracking info - one that wasnt my address. They told me “oh thats amazon’s fault, you should reach out to them”. Well needless to say that this is a total waste of time. Its not like I can get another brand to replace them. So im stuck with a light system that doesnt last more than 2 years. While I write this another bulb went out. Another one… Im not looking to go back and forth with customer service. Its a waste of time. So buyers beware, lights dont last. Its not like a normal bulb, you cant get another brand to replace. Customer support is a waste of time.
