Start with the ceiling condition.
The first decision is usually whether you are preserving an existing fluorescent housing, replacing it inside an existing grid, or lighting a new ceiling. That choice narrows the product family faster than comparing wattage first.
Consider a retrofit basket/kit when the housing and grid condition are worth preserving.
Verify housing dimensions, wiring, driver/ballast removal, controls, emergency equipment, and desired appearance.
Choose a complete troffer or flat-panel family sized for the existing grid.
Confirm grid size, plenum depth, mounting method, controls, emergency requirement, and ceiling condition.
Start with the ceiling system and desired visual effect before narrowing families.
Back-lit, edge-lit, volumetric, lens style, surface/suspension accessories, and control package can all change the ordering configuration.

Nominal size is only the beginning.
Confirm the actual ceiling grid, plenum/access conditions, and whether surface or suspension accessories are needed before ordering.
Simple, efficient panel construction.
Useful where the project wants a clean luminous plane and the available plenum/mounting condition supports the fixture depth.
Thin visual profile.
Often selected when fixture depth or architectural appearance matters. Compare efficacy, driver, frame construction, and warranty—not thickness alone.
More optical form inside the grid.
Useful where distribution, visual comfort, familiar troffer appearance, or retrofit compatibility matters more than an ultra-flat panel profile.
Most interior mistakes happen before the fixture is chosen.
Capture the ceiling and control requirements first so product comparison stays inside valid families and accessory combinations.
A retrofit can reduce labor, but only if the housing, dimensions, wiring, emergency equipment, and final appearance make sense to preserve.
