T8-T5 High Bays vs. HID Lighting
When it comes to right down to it, numbers don't lie. When it comes to high bay lighting, the three most important numbers are: System Input Watts, Maintain Lumens & Color Rendering Index (CRI).
When these three characteristics, lighting can be compared. WATTAGE IN is your cost to operate. LUMENS OUT determines the number of foot-candles that will be produced. And lastly, the CRI indicates how well the light will help or hinder your ability to perceive different colors within the lighted area.
Let's compare 3 common fixtures.

* Lumen Maintenance Percentage are used to predict the anticipated Lumen output of a light source in relation to the initial rated output of the lamp.
**Fixture Efficiency is the amount of light(Lumens) leaving the fixtures vs the amount generated by a given light source within the fixture.
***CRI is the Color Rendering Index is the lighting source ability to accurately render the colors of illuminated objects. The higher the CRI the better objects will appear.
