For the price, this is the best LED "Stadium" light out there. Very well built, amazing LED output, and versatility of mounting. ( No matter what size you buy, each 100W light can be attached or separated as needed) One of my lights seemed to have some crystalized film on the inside of the light but it doesn't affect the output. I have a horse dressage arena on my property. I purchased two 300W sets of these lights, and have them in pairs of 2 (6 total 100W units) on 3 25 foot flagpoles. They EASILY light up the whole arena. I could use more and make it brighter, but I couldn't be happier. Even if some of these die, they are absolutely worth the money. I previously tried some 400W Solar lights, and they were no where near the quality nor the brightness.Used 4 sets of lights to light a standard size horse riding arena. Great light. Love the fact that I could point the light in the needed direction. Great price. Arrived in time and new condition.The light assembly I bought was the 300 watt one. The install was fairly easy. I did have to buy a 3 to one junction box to tie in the 3 lights to the one power. Installed a photoelectric switch inline with it and ran power to the pole. First night I was actually worried the neighbors would complain but all I got was compliments and even wanted it adjusted to aim to more of the street. Which I did. I also sealed the 3 cords that go into the housing. Not sure how well it was sealed from the inside. I couldn’t be happier with it. Has been installed for about a week and has worked flawless. The first picture is taken off of our camera system. Update 7/29/2022. One light has failed so far. I will contact seller and see what happens. The lights have been fantastic as far as lighting up the area but now it worries me that one has already quit. Will update when I find out how hard it will be for warranty.it has a nice white light, very brightAn almost perfect product,. I would have liked this light much better if it had had a cord I installed it for my neighbor as it required a metal extension box so it could be hardwired to her light fixture since it only has a short non-terminated electrical cord. The cord is so short it is almost useless, I attempted to open the fixture to replace the cord and found that the fixture was unable to be opened as it is glued shut and unserviceable. I can only imagine all the people doing cord splicing to make this unit usable out there. Don’t try and splice this cord without using something like a handy box, do it correctly and avoid a fire. Aside from the shortcomings of the electrical cord and being completely unserviceable, the light is heavy duty, very bright with good color and one of these is sufficient for a single car garage.I'm on a quarter acre....This light lit up the entire yard so much that it was just as clear as day on the darkest night.I had to aim the light down because it did carry to light up the neighbors yards and houses behind me.All I can say this did the job and I was not disappointed at all.Its well made and is solid.The lamp is made in China and the wire color conversion is in the direction.3 wires, simple installation.The pictures made the yard look lighter then it actually was.You wouldn't be able to see anyone without the light.Lights up really well! I use it for my batting cage business.I just received this light this afternoon. It came with a 3 way weather proof combiner so you could power all 3 lights off of a single power cord. Was able to put it together in 15 minutes or less. Didn't seem to be as bright as I expected when testing it inside during the day. Will have to wait until tonight to see if it fills the backyard with enough light or not.Update: This light is definitely bright enough... too bright for my use actually. With all three of the 100W light fixtures lit up, it was lighting up my 3 1/2 acre back yard + the back side of the lake which is 400+ feet away (which was nice). But it was also blinding drivers coming up the gravel road from the west and drivers coming down the blacktop from the south. I ended up breaking the light up into three separate fixtures, but have only installed two so far until I can find a third mounting bracket that fits the third light.Update 3/25/2021 - Several (7 - 10) LED bulbs went dark after about 4 - 6 months. Now the rest of the LED bulbs are very dimly lit. I thought my cord was bad but when it got really dark and I was standing in front of the lights I could tell they were just very very very dim.
