Using the Milwaukee M12 Paint and Detailing Color Match Light is a breeze. First, make sure your M12 XC4.0 battery is fully charged and insert it into the light. Then, you can start by choosing one of the five color temperatures according to your needs, like early - morning light or mid - day sunlight. After that, select one of the three brightness modes within that color temperature. This way, you can get the perfect lighting for detecting paint scratches and looking at metallic parts. When you're done using it, find a metal surface to stick it to with the built - in magnet for easy storage. As for maintenance, since it's resistant to most paint and body shop chemicals, a simple wipe with a clean cloth after each use is usually enough. Avoid dropping it from heights greater than 6 feet, as it's only drop - rated to that height. And remember, the LEDs have a limited lifetime warranty, so you don't have to worry about replacing them.
