This LED light bar comes in a pack of two and each of the bulbs provides 18W of light. This makes it very bright even during the day thus promoting efficiency. With a die-cast aluminum-housing lens, it can serve you in the long-term. In an effort to further boost durability, it is designed with a waterproof, dust-proof, as well as a rustproof feature. This is reinforced with its stainless steel spot beam. Its adjustable brackets will allow you to choose on the direction the beam faces. In addition, it features a 30-degree long-range focused beam that penetrates through darkness to provide lighting over a longer distance.
