Keystone High-Output LED Replacement Lamp
Stupendously Bright, Remarkably Efficient
Keystone's High-Output HID Replacement Lamps are built for long life, bold illumination, and dependability. This corn cob delivers efficient, powerful light - with outputs up to 71,000 lumens - and its integrated, precision-engineered cooling fan provides outstanding heat dissipation, helping to ensure excellent performance. Adjustable outputs give installers and contractors maximum flexibility, extending Light Made Easy® throughout an outdoor environment.
The LED lamps deliver up to 71,000 lumens while maintaining a remarkably compact profile. That brilliant lumen output and the lamp's reliability are made possible through intentional engineering focused on thermal management - one of the most critical factors in high-output LED longevity.
At the heart of its design is an integrated cooling fan. The fan, part of all models 35W and higher, is built with rugged materials actively managing heat, supporting consistent light output, and helping to protect internal components for the life of the lamp. In several models, the fan also features precision ball bearings to reduce vibration and further minimize failure points.
Complementing the fan is an innovative internal architecture, including strategic driver placement, that optimizes airflow and heat dissipation without adding bulk.
Keystone's High-Output lamps are available in models spanning 9-450W, including high-voltage 277-480V options (120W and up) to expand compatibility across existing installations. Keystone Power Select and Color Select provide added flexibility, helping distributors reduce SKU counts while meeting a wide range of project needs with adjustable wattages and color temperatures.
Ideal for high bays, low bays, wall packs, post-tops, and shoebox luminaires, these lamps are UL Type B ballast bypass operation with 4kV surge protection, DLC Listed, mercury-free, and built for instant-on performance - even in cold environments.
Typical Applications
High Lumen Output
The top-end 450W high-voltage lamp is capable of putting out more than 71,000 lumens, equivalent to a stadium light, and efficacy is up to 174 lm/W, meaning that these lamps are remarkably energy efficient. That helps save on money and maintenance.
Compact Form Factor
With rigorous engineering, Keystone designed the LEDs, driver, and components of these HID replacement lamps to fit into a small form factor - and the enclosed applications to match - without sacrificing light output.
Engineered for Reliability
Thermal management is critical to high-output HID replacement lamps. These corn cob lamps feature an integrated cooling fan (35W and up) engineered as a core system component to actively manage heat and protect performance for long life. Keystone invested heavily in fan design, materials, and tolerances to address one of the most common failure points in high-lumen retrofit lamps. Additionally, many models feature precision ball bearings to reduce wear and support consistent airflow, ensuring dependable operation.
Power and Color Select
With 3 field-adjustable wattages per lamp and 3 CCT (3000/4000/5000K), it's 9 lamps in 1, providing for more customization.
A Full Range of Options
The lamp is available in wattages ranging from 9W to 450W. It's also available with E26 and EX39 base options and in 120-277V and 277-480V options.
Bypass the Ballast
These LED HID lamps feature an integral Keystone driver, eliminating the need for a ballast or external driver and ensuring dependability and long life, saving on maintenance and reducing energy use. And as with all products, Keystone's engineered solutions ensure that these lamps fail safely in the potential of a ballast miswire.
