How do I adjust the brightness on the Coleman 2000024375 390 Lumens Twin LED Lantern?

To adjust the brightness on the Coleman 2000024375 390 Lumens Twin LED Lantern, follow these steps:

• Locate the rotary dial (control knob) on the front of the lantern base.
• Turn the dial clockwise to turn the lantern on and increase the brightness.
• This model features a dimmer switch, allowing you to stop at any point between the lowest and highest settings to achieve your desired light level.
