High-Output
Corn Cob

Stupendously bright, remarkably efficient.

The Ventra™ 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 your outdoor environment.

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, we 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. Ventra™ corn cob lamps feature an integrated cooling fan (35W and higher) 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. The fans feature precision ball bearings to reduce wear and support consistent airflow, ensuring dependable operation.
