Frequently Asked Questions

Q: Will this E14 R39 25W bulb work with my lava lamp?

A: Yes — this bulb is specifically designed as a replacement for lava lamps and glitter lamps that use an E14 small screw cap (SES) fitting. The 25W output generates the right amount of heat to warm the wax inside the lamp, creating the classic lava flow effect. Always check your lamp's base cap type before purchasing.

Q: What voltage does this lava lamp bulb support?

A: This R39 reflector bulb operates at 220–240V, making it compatible with standard household mains electricity in the UK and Europe. It is not suitable for 110–120V North American circuits without a voltage converter.

Q: Can I use this bulb in other light fittings besides a lava lamp?

A: Absolutely. Thanks to its standard E14 small Edison screw (SES) base, this bulb fits a wide variety of luminaires including bedside lamps, wall lights, pendant fittings, and more — anywhere an E14 base is required.

Q: Is the R39 bulb clear or frosted?

A: This bulb features a clear (transparent) glass finish, which allows full light transmission and gives a bright, clean aesthetic suited to decorative lamp bases like lava lamps.
