Need a high-output bulb for a greenhouse or outdoor area?
This S W Clarke self-ballasted mercury vapour lamp is 250 watts with an E40 screw base.
It's an elliptical shape with a frosted finish, and it puts out a daylight white light (5000K-6500K) – great for plant growth or general illumination.
No external ballast needed, just screw it into a standard 230V socket and you're good to go.
Energy rating is C, but it's tough and long-lasting – up to 10,000 hours.
Also CE marked for safety.
Use it indoors or outdoors.

Comes as a single bulb.
