Using this Milwaukee M18 ROVER Dual Power Flood Light is easy. First, you can choose to power it either with M18™ REDLITHIUM™ batteries or by plugging in an extension cord. If you use the XC5.0 battery, you'll get up to 12 hours of run - time. To adjust the lighting direction, rotate the light head up to 120°. You can hang it overhead using the integrated keyholes. There are three output modes, so you can select the one that suits your brightness and run - time needs. When it comes to maintenance, keep it clean and dry as it has IP54 dust and water resistance, but don't expose it to extreme conditions. It's impact - resistant, but try to avoid dropping it. The tool has a 5 - year warranty and the LED has a limited lifetime warranty, so if there are any problems, you can get it sorted out.
