Bought the two pack of the 60W, 6000 lumen floodlights to replace our ancient halogen fixtures on the back of our house. The main problem with the old lights was that they weren't sealed, so bugs would get into the fixtures and break the very delicate, expensive bulbs, over and over again. TL;DR: These are sealed, waterproof, and so bright that we honestly worry that the neighbors might come complaining to us that it's keeping them up at night. Great value for the money.Installation: These come with bare red/black wire for splicing into AC power. To install, you will need some way of mounting it to the wall and some pressure twist-on nuts to secure the romex to the cables. Go with smaller than you think you need, since the wire from the light is pretty thin. I ended up just buying replacement gang-box covers from the hardware store and cutting a hole in them and mounting the lights straight to the old boxes from the original lights. This worked surprisingly well and was very easy to do, just make sure you don't oversize the holes so that it maintains a pretty tight seal. Unless you have a right-angle screwdriver, you will probably need to disassemble the LED panel from the stand that it ships attached to in order to attach the stand to the wall. After that, just re-install the LED onto the stand. The whole process, including drilling holes and getting the old fixtures removed, only took about 30 minutes per light. That said, if you are uncomfortable with electrical wiring, please just hire an electrician to do it for you.In use: These units are sealed, so no amount of stupid bugs smashing head first into the poly-carbonate face plate is ever going to break through it. The back is aluminum and acts as a heatsink to keep the diodes cool, so it should last a really long time (going on 6 months at this point, several hundred hours of on time with no issues). The lights come on instantly, with no delay. They don't make any kind of humming noise, which is a nice change from the halogens. They use 1/5th the power of the 300W halogen bulbs they replaced and put out considerably MORE light anyway. Our back yard is about 100x100', and two of these lights cover the whole thing like stadium lights. You could easily play sports in the middle of the night with no moon light with these on. It's a legitimate concern that the neighbors might complain that they are too bright, so we angled them way down to try and mitigate spill over into their yards.Overall, very happy with these lights. Installation was easy and they just work, no questions asked.
