T12 (1 1/2" Diam) Linear Retrofit LED Bulbs (To replace fluorescent)

Still have those old T12 fluorescents? Now you can change to LED tubes with various installation methods. Type "A" lamps work off existing ballasts with no re-wiring required. Type "B" are Bypass lamps that work off direct line voltage by bypassing the ballast. Be sure to read the specs.

Note: Philips portfolio now contains two categories: MasterClass (exceeds industry energy efficiency requirements for demanding applications) and CorePro (meets industry standards for basic lighting needs). See product specs for more details.

To check ballast compatibility on Philips LED tubes go to: https://www.usa.lighting.philips.com/home and click on Support & Contact, then Product Literature, then InstantFit LED Lamps Ballast Compatibility chart.
