4 Pack LED Troffer 2x4 FT Retrofit Kit 36W 5000K - Easy Install

Our review of the 4 Pack LED Troffer 2x4 FT Retrofit Kit finds it best for contractors, facility managers and DIYers who want a fast fluorescent-to-LED upgrade with minimal fuss. The single biggest reason to buy is the magnetic retrofit design that makes installation genuinely quick - most users can drop the magnetic driver and two magnetic strips into an existing troffer in under five minutes and restore reliable, bright 5000K daylight output without rewiring a ballast.

Key Features

• Magnetic retrofit: The magnetic driver and strips allow a tool-free swap into existing fixtures so retrofits are fast and low disruption.
• Long lifetime: Rated for 50,000+ hours, the kit reduces frequent replacements and supports years of continuous use in commercial and utility spaces.
• High efficiency: At about 150 lm/w and 5400 lumens per kit, it delivers strong light while cutting energy use versus traditional fluorescent sources.
• 0-10V dimming: Compatible with 0-10V dimmers for controlled light levels when your dimmer type is supported.
• Broad voltage range: Works on 100-277V AC, making it suitable across many building electrical systems.

Who It's For

This kit is ideal for maintenance teams, electricians and homeowners who want to convert existing T8/T10/T12 fixtures to modern LED light quickly and with minimal cost. Facilities with many troffers will appreciate the time savings and consistent daylight 5000K output for work areas, storage rooms and laundry spaces.

It is less suitable for installations that require integrated smart controls beyond 0-10V, or for fixtures where magnetic mounting is impossible due to nonmetal interiors; in those cases a hardwired LED retrofit or new troffer may be a better choice.

Pros & Cons

Pros

• Very easy installation using magnetic driver and strips, often under five minutes per fixture.
• Bright, daylight 5000K output and high lumen efficacy deliver good light for workspaces.
• Long rated life of 50,000+ hours and energy savings compared to fluorescent systems.
• 0-10V dimming support and wide 100-277V compatibility increase flexibility.

Cons

• Some buyers reported missing parts or delivery delays, so check contents before installation.
