Product Description

This high-performance electronic ballast is built for professionals who need rock-solid reliability in demanding environments. Supporting 4–6 T8HO or T12HO fluorescent lamps with a combined length of 6 to 48 feet, it’s the go-to choice for UV systems and high-output fixtures.

With parallel lamp wiring, the system keeps running even if one lamp fails—because downtime isn’t an option. Its universal input voltage (120–277VAC) and cold-start capability down to -20°F (-30°C) make it ideal for both indoor and outdoor-rated applications.

Quiet, efficient, and certified to meet major standards (UL, cUL, FCC Part 18, Class P, Type HL), the KTSB-E-0848-46-UV offers unmatched performance in commercial and industrial lighting setups.
