These unique top brand Venture Lighting Dual SON & Mercury Bulbs are designed to work with either SON or Mercury fittings, and give you the same quality of light associated with metal halide. This makes them ideal for factories, retail environments and sports halls, where superb light quality is essential.


We stock these lamps in both 250W and 400W versions and they come in a giant screw fitting, and are suitable for existing installations that already have an ignitor.

Hassle free

As these lamps have the flexibility of working in a variety of different types of fittings, you can keep your existing fittings and vary the types of lamp you use, giving you complete control. Their long life of up to 15,000 hours means they will give you bright light for years.
