Long life lamps

Venture Lighting Europe's new Twin-Arc sustainability metal halide lamps provide lamp life of up to 50,000h when combined with Venture's electronic gear, making them suitable for applications where re-lamping is costly and/or disruptive.

The twin arc configuration enables near instant re-strike of the unlit arc when the other main arc has been extinguished by a mains failure, thus improving health, safety and security.

The new lamps comprise two separate arc tubes in the same lamp envelope. Only one arc ignites at a time - alternating each time the lamp is switched on. This ensures equal use to maximise lamp life and reduce maintenance costs. The company says a further benefit is that in the event of mains failure or momentary outage, the unlit arc tube is cooler and ready to ignite quicker than a standard lamp.
