LED troffers and LED retrofit kits are not the same, but they can both replace previous lighting fixtures. LED troffers are cost-effective alternatives to traditional fluorescent fixtures. They are designed for drop ceilings in commercial and institutional applications such as offices, schools, hospitality, healthcare, and other commercial and industrial applications. On the other hand, LED high bay retrofit kits are LED fixtures that feature common lamp bases to allow you to keep your existing high bay fixtures while replace the metal halide or HPS bulb with a high powered LED luminaire.
Not only are retrofit kits more cost effective, but they provide an easy way to update outdated lighting fixtures. They are energy efficient alternatives to incandescent bulbs or metal halide bulbs. They feature long life spans and high lumen output with low energy consumption.
LED is the way to go, it just depends on which area you are trying to light. For more commercial uses, go with LED troffers. If wanting to upgrade high bay light fixtures in places like warehouses, choose an LED retrofit kit.
