I really haven't used this yet, but I did take it outside at night just to see what I bought. I it is almost like a spotlight. It really gives off a bright light. If course being18 volts it should huh. I have a Dewalt 18v drill what came with two of the ion batteries, but..........I wonder how many people bought this light,  thinking the batteries came with it. These batteries cost at least 4 times what the light cost if you go to Lowes to buy them. They come in a two pack. I don't know if you can buy just one. If you didn't have batteries already the way I did, it would probably make this not worth while. Boy, dat makes for an expensive flashlight.
