Key Technical Details:

• Long Life: Rated for a reliable lifespan (L70) up to 25,000 hours, reducing the frequency of replacement cycles.

• High Luminous Efficacy: Produces 54 lm/W, providing high light levels for wide-area outdoor lighting.

• Required Control Gear: This lamp is a High-Intensity Discharge lamp and will not operate without the appropriate external Mercury Vapour Ballast (Control Gear). Do not connect directly to the mains.

• Applications: Primarily used in street lighting, car parks, industrial halls, and general outdoor area lighting in existing luminaires.

Mercury Vapour (HQL) lamps contain toxic mercury (21.8 mg) and are subject to global phase-out regulations due to their high energy consumption and environmental impact.

We highly recommend replacing this lamp with the specialized LEDVANCE HQL LED Retrofit version. The LED alternative:
