A:Answer These lights are 80 lumens at full power and 40 lumens at half power, with a lighted angle of 90 degrees. Generally, the higher the lumens, the brighter the lights, and while total distance penetrated will depend on angle, area covered, and the reflective surfaces, this light is a good choice for continuous lighting of flags, signs, landscaping, paths, steps, and decks, so think under 10 feet for both full and half power. If you are looking for something stronger, we sell lights with triple the lumens which will cover larger areas or provide more light.
