Using the DeWalt DCL043 20V MAX Jobsite LED Spotlight is easy. First, make sure you have a charged battery (sold separately) and connect it to the spotlight. You can choose between the high and low brightness settings according to your needs. If you need a lot of light quickly, go for the high setting. For longer use, the low setting is a good choice. The 90 - degree pivoting head is very useful. You can adjust it to shine light on the work surface you're focusing on. You can either stand the spotlight on its base and let it project light hands - free or use the integral hook to hang it up. When it comes to maintenance, keep the lens clean. The over - molded lens cover is durable, but it's still a good idea to wipe it gently with a soft cloth. Also, store the spotlight in a dry place when not in use. And always follow the battery charger's instructions to ensure the battery's long - term performance.
