Industrial Performance Meets Total Control

Upgrade your high-ceiling facility with a lighting solution that adapts to your specific environment. This Satco LED Hi-Bay lamp isn't just a bulb; it's a complete efficiency overhaul. Designed to replace power-hungry 400W to 600W metal halides, this unit features on-lamp wattage selection. You can toggle between 100W, 120W, and 150W settings during installation, giving you the power to customize brightness levels based on the mounting height or the task at hand.

The Type B ballast bypass design streamlines your electrical system by eliminating the ballast—the most common point of failure in traditional HID fixtures. By direct-wiring to the 120V-277V line, you ensure long-term reliability and significantly reduced maintenance labor. With advanced convection cooling and an IP64 rating, this lamp is engineered to thrive in demanding industrial spaces, from dusty factories and humid health clubs to expansive athletic arenas and warehouses.

• Power Selectable Versatility: Adjust between 100W, 120W, or 150W to dial in the perfect light level for your space.
• Superior Visibility: Delivers up to 21,000 lumens of high-quality light, ensuring safety and precision in work zones.
• Rugged Engineering: Rated for use in enclosed fixtures and equipped with 4KV surge protection to withstand voltage spikes.
• Ballast Bypass Efficiency: Simplifies your fixture by removing the ballast, leading to higher energy savings and fewer points of failure.
• Long-Term Reliability: A 50,000-hour rated life paired with a 5-year warranty means years of maintenance-free operation.

Whether you are retrofitting a gymnasium for better clarity or upgrading a manufacturing plant for energy rebates, this Mogul Extended (EX39) base lamp provides a compact, powerful, and future-proof solution for any high-bay application.
