G9 LED Bulb 4.2W 470lm Non-Dimmable - Warm White 2700K, 2 Pack

This is a G9 capsule LED, the small two pin lamp that pushes straight into its socket rather than twisting in. It draws 4.2 watts and gives 470 lumens, and the retail pack gives it as a replacement for a 40W halogen capsule of the same shape. The light is 2700K warm white, the softer yellow toned white that halogen capsules gave, so changing a whole fitting over in one go will not shift the character of the room. Each box holds two bulbs, and the energy rating is E.

G9 is the cap you find in fittings with no room for anything larger: multi arm ceiling lights and chandelier style pendants, wall lights, compact table lamps and picture lights. A capsule has no reflector behind it, so the light goes out in all directions rather than in a beam, and the pack quotes its 470 lumens in a sphere for that reason. That makes it a good match for fittings that do the shaping themselves, whether that is a glass shade, a set of crystal droppers or an opal diffuser. Two bulbs to a box is practical here, because fittings of this kind often hold several lamps at once and an unused spare in the drawer is never wasted.

The specification and the pack both say these are not dimmable, so they want a plain switched circuit; a non dimmable LED left on a dimmer will usually flicker or hum. The pack prints a 15 year lifespan and 15,000 hours of running, which is a little under three hours a day across those fifteen years. Each unit here is one box of two, and the minimum order is twelve, sold in multiples of twelve. Our wider range carries the same 470 lumen output on a B15 (SBC) cap, in plain and candle shapes, if other fittings need matching.

How do I tell whether my fitting takes a G9 bulb?

A G9 lamp has two stiff wire loops on its base and pushes into the socket rather than turning. The cap code is usually printed on the base of the old lamp or on the label inside the fitting, so check there before ordering.

Can I use these on a dimmer switch?

No. Both the specification and the pack give these as non dimmable, so they need a plain on and off circuit. A non dimmable LED on a dimmer will normally flicker, buzz or fail early, so pick a dimmable lamp if the circuit has a dimmer on it.

Will the light match the halogen capsules I am replacing?

The colour should look familiar: 2700K is the warm, slightly yellow white that halogen capsules produced, rather than the bluer light of a daylight lamp. At 470 lumens the pack gives it as a 40W replacement, so a fitting full of old 40W capsules should read at a similar level.

How many bulbs do I receive?

One unit of this listing is a box of two bulbs. The minimum order is twelve units in multiples of twelve, so the smallest purchase is twelve boxes, which is twenty four bulbs in total.

Is an IP rating given for this lamp?

The manufacturer does not state an IP rating for the bulb, so there is no figure we can publish. Where the lamp can be used is governed by the rating of the fitting it goes into, which the fitting's own instructions will state.

How long should one of these last?

The pack prints a 15 year lifespan and 15,000 hours of use. Those two figures fit together at a little under three hours of use a day, so heavier daily use will work through the hours sooner.
