Horizontal

Expand possibilities with an LED replacement for metal halide.

Versatile Keystone LED HID horizontal replacement lamps are the optimal LED lamps for upgrading area lights and wall packs from legacy lamps. They provide improved energy efficiency without changing the fixture.

Light Made Easy

Power Select and Color Select

Most of our horizontal LED HID replacement lamps are available with field-adjustable technology, allowing you to change the power output and color temperature at the touch of a switch.

Direct light where needed

All our horizontal LED lamps feature rotatable bases so you can aim the light in any direction, offering flexibility and range.

Xpander technology

Keystone Xpander technology – available on 80W and 110W models – offers a solution for hard-to-fit shoebox and wall pack light fixtures: simply swing out the two sides and the resulting beam angle is focused in one direction.

Heat Sink

SmartCool — for the hottest conditions

Our SmartCool technology extends the life of our LED HID replacement lamps by using a thermal sensor that activates during extreme high-temperature conditions, reducing power by up to 30% to cool the lamp. Once the sensor reaches an acceptable temperature, the lamp gradually returns to full output.

Large heat sink

A large heat sink dissipates heat and and guides away water intrusion, ensuring the lamp stays cool and helping maintain its longevity.

A variety of applications

With their rotatable base, ability to shed heat, and range of sizes, our horizontal LED HID replacements are ideal for tight and enclosed spaces, including shoeboxes and sign cabinets.
