hykolity 10 Pack 4FT Linkable LED Shop Light, Utility Shop Light Fixture, 4400lm, 42W [250W Equivalent], 5000K Daylight Shop Lights for Garage, Hanging or Surface Mount, with Power Cord, ETL, Black

These double tube lamp fixtures have functioned very well for over a year since installation. So far, these lamps have come on reliably and do not flicker and provide a lot of light and do not provide any noticeable hum or buzzing. I cannot comment on RFI interference since they are not in an area where they might create noise in TVs or radios. Bear in mind they are very simple in design and not robust, nor do they contain any shield or reflector. If they are installed where they will not be hit or under mechanical impacts or stress, they work well in providing a lot of light for their price. Installation is very simple and good instructions are included with these lamps. I bought them to replace other Chinese origin LED lamp fixtures which failed after a couple of years of intermittent use. The previous lamps were and these are installed a storage room in the basement of my house so they see rather little use and certainly very few hours of total use. I would buy them again!

Works great. Good and bright.

Bright and inexpensive. Very lightweight. We needed a lot of illumination for our classroom and we got it. We daisy-chained 5 on one side and 4 on the other and felt we had enough light that we had one left over to use somewhere else. We sometimes have little old ladies with failing vision and this provides enough light to very brightly fill a 15’x25’ classroom. Can’t beat the price. No humming like the old fluorescent lighting ballasts.

These light's are a great value. I live in a 2 story home. Upstairs is the living quarters and downstairs is a garage. The sq footage of each is ~800. I installed these in the garage. I flush mounted them to the floor joists and they work great! Plenty bright and have a nice frequency that doesn't look too sterile or blue. I am not a fan of light over 5k hz. The included hardware is perfect for flush mounting. For the 800sq ft space I used 8 lights. The difference is, excuse the pun, night and day. Before I purchased these I read up on a common failure point. The on/off switch in the middle of the power cord has a tendency to overheat and melt or short out. To prevent this I cut the switch of of each light and soldered and heat shrinked the AC power wires together. If you do this pay attention to the polarity on the wires! I also ran a separate 15 amp circuit from my fuse box with independent duplex outlets for every 2 lamps. This is probably overkill, but the best way I could see to safely install these. I imagine with this setup the lights will last several years. The fit of the flush mount clips was perfect. Rock them in one side at a time and they snap in perfect. I'll report back with some pictures of my setup and the durability of them. I just installed them today so the jury is still out on how long they will last. All in all at the price I don't believe they could be beat. Even if one or two goes out in the next year I'll feel I won. I would give them 5 stars if I hadn't have had to hardwire each one. That took some time, but was worth it to me.

I have absolutely no complaint about these lights they are easy to install, as long as you know how to use a tape measure, they even come with the hardware for installation although in my opinion the hardware is pretty cheap I decided to use drywall type screws because I think they were a better fit and I could use the cordless drill to install them without stripping them, the light color spectrum is typical of a fluorescent white light (they aren't blue but they aren't exactly something you would want inside your house they are definitely a portable school house building fluorescent light in their color spectrum if that makes any sense), they are not yellow they are what I would consider a pure or true white light. As I stated above they come with the hardware and they are already wired for the cord, it's already been a couple of months but if I remember correctly the cord just plugged into the side of the light no wiring involved the cord length is probably about 4 or 5 ft, in my opinion it could be a little longer but again price reflects what you get these lights are great. The one thing I wish you could do with the lights is daisy chain them together seamlessly but you would have to run the cord from one to the other. Anyways long story short My garage went from being dark to I can now see all the spiders and messes and I am now aware of how badly I probably need to clean my garage.

I replaced some shop lights in my garage. These new ones don't have a reflector on the back, and I worried they wouldn't be bright enough. However, they work very well. I don't miss the reflector and find that there is more upward light to brighten the ceiling. I have these on a motion sensor switch. When I installed them, they did not fully turn off but just went 'dim' when I expected them to be off. I was worried that this operation might shorten their lifespan. The problem is that many old motion detectors run a small current through the lights to power their motion-sensor electronics. I replaced the old switch with a new one that runs the current either to a neutral (if available) or on the ground wire, which should always be available. Now, they turn completely off like they should. I also connected a couple to the garage door opener. I bought an adapter that converts a light socket into two outlets and a light socket. The regular light bulb fit into the adapter, and both fit into the "Liftmaster" opener—no changes required. Also, there was plenty of space to route the cable from the new LED strip into the adapter. These lights don't have a three-prong plug, so a grounded outlet isn't necessary. They do have a polarized plug -- if you're trying to plug It into an outlet from the 50s or 60s, you'll need an adapter.

Perfect! We are using in outdoor containers. Works perfect! Super bright and each has an off /on switch! Great great!

Product would get a 6 star if wire nuts were furnished with lights. Lights looked really cheap, flimsy, not too confident judging by appearance. Lights were very easy to mount and the brightness was truly amazing. Replaced old fluorescent lights in my barn with these. These are 10x better. Gonna buy another 10 pack to have on hand.
