Good quality, bright, good light projection pattern, good choice for snowblowers
Color: 2Pcs 18W LED Flood Light, Color: 2Pcs 18W LED Flood Light
This review is ONLY for the Nilight model 1260LM (the package of TWO of them). This product has a flexible design, allowing it to be used in a variety of ways when you want to add illumination to a vehicle of some kind. It can be used as add-on fog lamps for trucks and off-road vehicle, it can be used as headlights for golf carts and such, and it is a good choice for adding headlights to snowblowers. The two mounting brackets allow swiveling and angling up and down for best aim and illumination pattern. Each 'lamp' assembly is mostly made of black anodized or black powder-coated aluminum, with a water-resistant design. The front 'lens' is Lexan or some other suitable clear plastic material with good, durable properties. The manufacturer claims that the included mounting hardware (bolts, nuts, washers) are stainless steel, but they seem to weigh too little to be SOLID stainless. Whatever they are made from, they do not attract strong (neodymium) magnets. Because I bought the lamps to use on my snowblower, I decided to replace the included hardware with solid stainless hardware. The large bolts for mounting the brackets are M8 x 1.25 and the smaller bolts for attaching the lamps to the brackets are M6 x 1.0. I also chose to purchase the smaller bolts with 'cap head' bolts, because it make lamp angle adjustment much quicker and easier. Each included bolt comes with a flat washer and a split-ring lockwasher, and the large bolts also come with nuts (the smaller bolts thread directly into pre-tapped holes in the lamp bodies). The included lockwashers make sense for the main mounting bracket bolts, but there is no reasonable place to use the lockwashers of the smaller bolts. I inquired of Nilight tech support, and they clearly had never thought about WHERE those lockwashers should be used, and they concluded that they probably should NOT actually be used. Each lamp has a short (perhaps 6") 'pigtail' cable coming out of one rear edge, and these cables each have a pair of wires inside; a RED one for + and a BLACK one for - . The user can wire these up any way that is desired, but probably they will be wired in parallel in most situations. I wish that the cables were longer; as it is, it is necessary to splice them to other cables in places that will not be hidden from view and/or otherwise protected from the elements. These lamps are designed to operate on 12VDC power, although the exact voltage is not critical. There is no need to use a special LED power supply, since the lamps include their own internal power conditioning circuitry. Powering these from 12VDC, EACH lamp will required 1A of current, to 2A total when wired in parallel. This comes to 12V x 2A = 24 Watts. In my case, I needed to power the lamps from a cordless power tool battery which produces a nominal 20VDC, which can drop as low as about 16V. Accordingly, I used one of the ubiquitous and inexpensive "DC Converters" (aka "DC-DC Converter") with an input having a voltage range that includes the expected 16~20V of the battery, and has a regulated 12V output, and has a Power (Watts) rating of at least twice the expected load, in this case a 60W one from Amazon. Since these converters have nearly a 100% efficiency, the input and output power (Watts) will be the same value, 24W. Doing the math in my case, an assuming an average battery voltage of 18V, the math is 24W / 18V = 1.3A. My battery has an Amp-Hour (Ah) of 4, so 4 / 1.3 = about 3 hours of operating time for the two lamps from a fully charged battery. My only gripes with the product have already been mentioned: - overly short power cords - poorly conceived hardware 'package'; the smaller lockwasher are useless, and the associated bolts should have had cap heads instead of hex heads (I won't complain about the lack of sold stainless steel hardware, since that would have driven the selling price WAY up)

Good bang for the buck.
Color: 2Pcs 18W LED Flood Light
I have bought 10 of these now. I put them on my work trailer and use them for reverse lights. They are cheap, easy to install, and they work very well. Now and then, I break one; they are exposed on my trailer and stuff happens, and these are so cheap it's not a big deal to replace them.
