Litetronics LED Magnetic Retrofit Kit

This new Litetronics RFM3T250A LED Magnetic Retrofit Kit measures 21 inches and operates at 30 watts with a 5000K colour temperature. It delivers 3140 lumens at 156 lumens per watt and a colour rendering index of 82. The unit runs on 120/277V AC and carries DesignLights Consortium certification.

Suited for facility managers upgrading T8 U-bend

Installers who need a magnetic-mount LED replacement for existing 1 ft by 2 ft U-bend troffers will find this kit fits the application. It is dimmable for adjustable light levels. Buyers requiring integrated emergency battery backup or built-in occupancy sensors should consider other options as this model includes neither feature.

30-watt LED replacement for T8 U-bend

The decisive specification is the 30-watt LED output designed as a direct replacement for T8 U-bend lamps in 1 ft by 2 ft fixtures. Magnetic mounting allows tool-free installation into compatible troffer housings. The 5000K colour temperature and 82 CRI suit general area lighting where accurate colour rendering is needed.

Questions about this item

Does the 21-inch magnetic retrofit kit need a metal housing to mount securely?

Yes, the magnetic strips attach directly to any ferrous metal troffer or strip fixture without tools or brackets.

What wiring step causes the most issues when installing the 30-watt driver on 120/277V circuits?

Connecting the driver leads to the wrong voltage tap; verify the supply is 120 V or 277 V before wiring the black and white leads.

How do I know when the 5000K LED array should be replaced instead of just the driver?

When light output drops below 70 % of the original 3,925 lm rating or colour shift exceeds the 82 CRI baseline, replace the entire kit.
