Get quick answers about the Luna Spare Bulb: which Luna Lamp sizes it fits, dimming capability, E27 fitting details, and how to replace it safely.
Quick answer
The Luna Spare Bulb is a dimmable LED bulb with an E27 fitting, designed as a direct replacement for Luna Lamps in Medium, Large, and Extra Large sizes.
What to consider before buying a spare bulb
The Luna Spare Bulb is purpose-built for the Luna Lamp series, so compatibility is straightforward if you own one of the three supported sizes. However, it uses an E27 (standard Edison screw) fitting, which is common in many lamps. If you plan to use it in a non-Luna fixture, confirm that the fixture accepts an E27 bulb and that the bulb's dimensions fit the shade or housing.
Dimmability is a key feature, but it only works if your lamp and wall dimmer are compatible with LED loads. Older dimmers designed for incandescent bulbs may cause flickering or reduced dimming range. If you experience issues, consider upgrading to an LED-rated dimmer.
