Frequently Asked Questions

What are the main advantages of upgrading from fluorescent troffers to LED troffers?

LED troffers save significantly on energy costs, last much longer, provide better, instant-on light quality, and often offer dimming options. They are the efficient choice for commercial applications.

Should I buy a new LED troffer fixture or an LED retrofit kit?

Choose a new LED fixture for new installs or if the old housing is bad. Use a retrofit kit to upgrade the LED components inside an existing, compatible fluorescent housing – often faster and cheaper for upgrades.

What's the difference between an LED troffer and an LED flat panel?

A "troffer" is the recessed troffer fixture body designed for grid ceilings. An "LED flat panel" is a specific thin light source technology (edge-lit or back-lit). Many modern LED troffers contain flat panels, but they can also use prismatic lenses, center basket, or parabolic designs.

How do I know what size troffer (e.g., 2x2 or 2x4) I need?

Troffer sizes (like 2x2 or 2x4 feet) match standard grid ceiling tile openings. Measure your existing fixture or the ceiling grid opening to determine the correct size.

What is the difference between a parabolic and a center basket troffer?

Both reduce glare. A parabolic troffer uses mirrored, grid-like louvers to direct light straight down, controlling reflections on screens. A center basket troffer provides softer, volumetric light by reflecting it off its curved central element for a more ambient feel.
