Key Features and Benefits of This Powerful Fixture

The white color also reflects light and contributes to the enhancement of efficiency.

Above all it is an exceptional value. It is both commercial grade in durability and affordable enough to justify a residential project, so you can expect many years of quality service without spending an extreme amount of money.

Understanding the Technology: Fluorescent Lighting Made Simple
LED technology is the new wave, but fluorescent, such as the Lithonia Lighting 483p90 is an established and very efficient leader. It works simply as follows: electrical current passes through the mercury of the fluorescent tube and the vapor produces invisible ultraviolet (UV) light. The UV light hits this white phosphor on the inside of the glass tube and illuminates it to give us the visible bright white light.
The result of this process is it generates much less heat and less electricity to create the same amount of light as the old incandescent bulbs, which saves you money in your utility bills. It is a tremendous blessing in your working room that has either a lamp which you can leave on most of the time, and which gives you enough light without heating up your room and costing you a fortune in electricity.

When the connections are safely in place and tucked into the junction box, you can carefully fit the lens in place, installing the fluorescent lamps with a quarter-turn in the sockets, and then reconnect power. And, of course, when in doubt, it is always better to consult a licensed electrician.
