Tridonic 2 x 18W Ballast - Twin


The non-dimmable Tridonic 2 x 18W T8 Ballast is an electronic high-frequency ballast, designed to run a pair of 18W T8 fluorescent tubes. The ballast has an average-rated lifespan of 50,000 hours, and is intended to replace an expired or inefficient ballast. It avoids any need to replace a complete fitting.

With its Intelligent Voltage Guard feature, the Tridonic 2 x 18W T8 Ballast automatically protects against overvoltage or undervoltage. It will also shut down defective or end-of-life lamps, preventing possible damage to the ballast and lampholders. The ballast restarts automatically after a lamp change.

An electronic HF ballast offers numerous advantages over a standard magnetic ballast, including an immediate start (less than 1.5 seconds in this case), no flickering or humming during operation, increased energy efficiency, and up to 50% greater lamp lifespan.

Usable within a wide -25°C to 80°C ambient temperature range, the top-quality Tridonic 2 x 18W T8 Ballast maintains a constant luminous flux, regardless of fluctuations in mains voltage. It can tolerate over 50,000 starts, to ensure long service life.

Easy to install, choose this market-leading brand of high-frequency ballasts and enjoy the best possible performance from your fluorescent fitting. The Tridonic 2 x 18W T8 Ballast is suitable for use in safety protection class I or class II luminaires.
