Description

This is a G4 LED bulb in a flat disc format: a round board 20mm across and 8mm deep, standing 31mm high on its two pins. It draws 1.2W and gives 135 lumens of warm white light at 3000K from a 12V supply, AC or DC. The figure in G4 is the pin spacing in millimetres, so it needs a G4 lampholder; G9 and GY6.35 holders space their pins further apart and will not take it. Compare it with your old bulb by lumens, not watts: lumens are the light you get, watts the power it takes.

It is for a G4 holder in a 12V fitting. The maker states no place of application, so before you order we would make three checks against the fitting itself. Voltage: it is rated for 12V AC at 50/60Hz or 12V DC, so check the voltage marked on your fitting or its transformer. Space: the holder needs room in front of it for a disc 20mm across and 8mm deep. Direction: the pins extend from the edge of the disc in the same plane as its face. That means its light, spread over a wide 120 degrees, goes out to the side of the holder rather than along the line of the pins.

The LEDs sit on the face of the board, and switched off they look yellow: white LEDs carry a yellow phosphor coating, which turns their light white once they are lit. Colour rendering is Ra 80, a usual level for everyday lighting, though close colour work calls for a higher one. It is not dimmable, so it wants a plain on/off switch rather than a dimmer. The rated life is 20,000 hours, a little over 18 years at three hours a day. In a fitting with several G4 bulbs, match them at 3000K so the light stays one colour.

Frequently Asked

How do I know my fitting takes a G4 bulb?

Check the old bulb or the fitting's instructions for the cap type. A G4 cap has two pins with their centres 4mm apart, while G9 and GY6.35 holders space their pins wider and will not take this bulb.

Which way does the light shine once it is fitted?

Out from the face of the disc. The pins extend from its edge in the same plane as the face, so the light, spread over 120 degrees, goes out to the side of the holder rather than along the pins. Check that suits the way your holder sits.

Will it work with the transformer already in my fitting?

The maker rates it for 12V AC at 50/60Hz or 12V DC, so check what your transformer or driver puts out. Some electronic transformers need a minimum load before they run steadily, and at 1.2W this bulb draws very little, so look for the minimum load printed on yours.

Can I use it with a dimmer switch?

No. The maker states it is not dimmable, so it belongs in a fitting worked by a plain on/off switch. If your fitting is on a dimmer, we would choose a bulb sold as dimmable instead.

Why does it look yellow when it is switched off?

White LEDs carry a yellow phosphor coating, and that is what you see when the bulb is off. Once lit, the phosphor turns the light white, and this bulb gives a warm white at 3000K.

How long will it last?

Its rated life is 20,000 hours, which is a little over 18 years at three hours a day. A rated life is a figure from testing, not a promise for every single bulb.
