Frequently Asked Questions

  • How many lamps does each fixture have?

  • What is CRI, and how does that make a difference?
    CRI stands for Color Rendering Index. This refers to the useable light that the human eye can process. A higher CRI it will make colors much more visibly distinct and pleasing. The CRI on a standard HID can be as low as 65 whereas the CRI with our fixture is into the 80’s+.
