Product Description

The Keystone KTSB-E-0416-12-UV-S Electronic Sign Ballast is built for serious lighting projects—think long sign runs, display lighting, and specialty UV applications. Designed to power 1 to 2 T8HO or T12HO lamps with a combined length of 4 to 16 feet, this ballast uses series wiring for consistent, even illumination across extended runs.

Thanks to programmed rapid start technology, it gently ignites lamps to extend their lifespan and reduce wear. Its wide 120–277VAC input voltage means it plays nice with both commercial and industrial installations. Whether you're lighting up signage for a storefront or backlighting a killer UV display, this ballast brings the performance, durability, and efficiency Keystone is known for.
