Led Light Bulbs

Keystone DirectDrive LED tubes eliminate the need for an external driver or ballast. For new construction installations, simply connect the 120-277-Volt line voltage directly to the sockets. For retrofit installations, bypass the existing ballast by cutting the wires and connecting the 120-277-Volt line voltage directly to the sockets. No ballast or driver is required.

• Replacement for conventional fluorescent lamp
• 50,000+ hour lifetime
• Approximately 40% more energy efficient that standard F32T8 lamps
• Environmentally friendly: no mercury used
• Frosted lens eliminates pixilation
• Improved lamp durability with shatterproof coated glass
