An efficient way to bypass the ballast in low and high bay applications.

Vertical LED HID Replacement Lamps

Keystone DirectDrive LED vertical HID replacement lamps are the ideal way to upgrade legacy metal halide fixtures to LED. Simply bypass the existing ballast by cutting the wires and connecting the 120-277V line voltage directly to the sockets. No ballast or external driver is required.

They feature Power Select and Color Select technology, so power outputs and color temperatures can be changed with the flick of a switch.


SmartPort compatibility

In addition, these LED replacement lamps are compatible with Keystone’s SmartPort sensors. SmartPort allows you to control your LED lighting and improve efficiency with ease. Simply insert the sensor (sold separately). The settings are adjusted remotely – no need to get on a scissor lift. Even if you choose not to plug in a sensor, the lamp will operate normally.

Sensor options include microwave, PIR, and photocell. The technology helps distributors stock multiple categories, since one sensor can work in many Keystone fixtures.
