Compatibility, usage and safety

• Fits any standard B22 bayonet lampholder. Check your fitting has enough clearance for the bulb's length and diameter before ordering — these are large, high-output bulbs.
• For use on a standard on/off switch. This bulb is not dimmable — do not use it with a dimmer switch.
• No IP rating is stated in the datasheet, so we do not recommend outdoor or damp-location use.
• Switch off power before fitting or removing the bulb, and let a hot bulb cool before handling.
