Buster Punch's Puck LED bulb is a statement-making light bulb that is perfect for clear or caged light fittings. Featuring a small puck-shaped LED light bulb, the Puck has been finished with an opal glass shell to give off a uniform warm-white light. Consuming just 1/50th the energy of traditional bulbs, the Puck LED fits in any E27 screw light fitting. Choose between a 5W dimmable or 2.5W non-dimmable warm-white LED to suit your requirements. Please note: the non-dimmable Puck LED bulb is intended for use with on/off switches only, while the dimmable Puck LED bulb requires a compatible dimmer switch. Buster Punch offer a range of switches to suit either option.
