Osram Ledvance QTP5 1x49w T5 Ballast
The Osram Ledvance QTP5 1×49 W T5 Ballast is a high‑performance electronic control gear designed specifically for a single 49 W T5 lamp. Supply voltage stands at 220‑240 V (198‑264 V line) with mains frequency of 50/60 Hz, making it suitable for typical UK installations. It incorporates advanced features such as filament pre‑heating for reliable lamp start, automatic shutdown at lamp end‑of‑life (EoL T.2) and automatic restart after lamp replacement — ensuring minimal maintenance and improved safety.
Built for longevity and efficiency, this ballast delivers a lifetime of up to 100 000 hours (at Tc = 65 °C with max 10% failure rate) and carries an Energy Efficiency Index of A2 BAT. It is non‑dimmable, operates at a high switching frequency (approx. 40‑50 kHz) to reduce flicker, and is certified for use in emergency lighting systems, open‑plan offices, corridors, sports halls and industrial applications. This makes it a reliable choice for modernising existing fluorescent installations with minimal disruption.
