LED flat panel lights are versatile lighting solutions that are commonly used across various settings due to their sleek design, efficient lighting, and energy-saving capabilities. Here are some of the most common applications for LED flat panel lights:

Motion Sensors: These sensors can automatically turn the lights on when motion is detected, and turn them off after a period of inactivity, helping to save energy.

When ceiling height is known, a fixture with the appropriate foot candle rating and beam angle to provide optimal coverage can be selected. The next factor playing into this will be room dimensions, which is a bit more tricky - especially for rooms with irregular dimensions. Simply using the square footage of a room to calculate the number of fixtures is not sufficient - instead, it is key that the fixtures are orientated in the most effective manner for the particular space. This can sometimes result in different size or wattage fixtures for certain parts of a room in order to provide optimal coverage.
