Description

This is a 30W R39 reflector bulb on an E14 small screw cap, sold by Eveready for use in lava lamps. It gives 180 lumens at 2,700 Kelvin, a warm white close in colour to an old household filament bulb, and the glass is frosted rather than clear, so light leaves the face of the reflector as a soft wash instead of a hard edged spot. The R39 code describes the shape: a reflector 39mm across the front, tapering back to the cap.

Lava lamps are the reason this bulb is still made. A filament lamp turns most of its energy into heat, and that heat rising through the base is what keeps the wax moving; a cool running lamp of the same brightness will not do the same job. If you are swapping an old bulb out, check two things first. The cap should be the narrow E14 screw rather than the wider E27, and the reflector face should measure 39mm rather than the 50mm of an R50. It is worth reading the wattage printed on your lamp's base too, because fitting more wattage than the maker allows will run it hotter than intended.

The pack prints a lamp life of one year, or 1,000 hours, which is short beside an LED and ordinary for a filament lamp; at three hours an evening that is close to a year of use. The energy label reads G, with a consumption of 30kWh per 1,000 hours. The specification lists the lamp as non-dimmable. Each unit is a single bulb and the minimum order is 10, sold in multiples of 10, which suits keeping spares in a drawer. It sits alongside our wider range of Eveready bulbs in B15, B22 and E27 caps, including candle, golf, GLS and pygmy shapes.

Frequently Asked

Will this fit my lava lamp?

Take the old bulb out and compare it. You need the narrow E14 screw cap, not the wider E27, and a reflector face of 39mm, and the wattage marked on your lamp base should be 30W or more.

How bright is 180 lumens, and what does 2,700K look like?

It is a low output by modern standards, roughly a soft glow rather than room lighting, and 2,700K is the warm yellow white of a traditional filament bulb.

Can I put an LED in my lava lamp instead?

Generally not. The wax is moved by heat from the filament as much as by light, and a cool running LED of the same brightness will usually leave the lamp sitting still.

Can I run it on a dimmer?

The specification lists this lamp as non-dimmable, so we would not put it on a dimmer circuit. A lava lamp is designed to run at full power in any case.

Is a wattage equivalent given?

No equivalence figure is printed on the pack or in the specification. This is a 30W lamp that draws 30W and delivers 180 lumens, so there is nothing to convert.

Does the manufacturer state an IP rating?

No IP rating appears in the specification or on the retail pack, so we do not list one. Treat it as an ordinary indoor filament lamp for an enclosed decorative base.
