Description

This G4 LED bulb is a flat, round disc: twelve small LEDs set across a white board, standing on two G4 pins. It measures 20mm across, 8mm deep and 31mm high including the pins, the three figures to check against your fitting. It draws 1.2W and gives 140 lumens at 4000K, a cool white, with a broad 120° beam. When choosing between bulbs, compare lumens rather than watts: lumens measure the light a lamp gives, watts only the power it draws.

It is for a fitting with a G4 lampholder on a 12V supply, and runs on 12V AC at 50/60Hz or 12V DC. A 12V lamp needs a transformer or power supply between it and the mains, so it must never be wired straight to 230V. G4 means two pins 4mm apart, so a fitting made for GY6.35 or G9 bulbs will not take it. The shallow 8mm depth matters where a cover sits close in front of it. A 120° beam is wide but directional, so the way the disc faces decides where its light falls. It is not dimmable, so it belongs on an ordinary switch, not a dimmer.

Switched off, the LEDs look yellow. That is their phosphor coating, which is how most white LEDs are made: it converts part of the blue light from the chip beneath, and the mix comes out white. The voltage is marked on the face of the board and the pins sit in a small black base. Its rated life of 20,000 hours works out at more than 18 years at three hours a day. Colour temperature shows when lamps sit side by side, so in a fitting with several G4 bulbs we would use 4000K throughout rather than mixing in warmer whites.

Frequently Asked

Will this replace the G4 bulb in my fitting?

Yes, if your fitting has three things: a G4 lampholder, which takes two pins 4mm apart; a 12V supply; and room for a disc 20mm across, 8mm deep and 31mm high with its pins. The 120° beam is directional, so check the disc can face where you want the light.

Do I need a transformer for this bulb?

Yes. It runs on 12V AC at 50/60Hz or 12V DC, so it needs a 12V transformer or power supply and must never go straight onto 230V mains. A fitting that takes 12V G4 bulbs is already fed by one. Some electronic transformers made for halogen lamps need a minimum load to work properly, and a single 1.2W bulb may fall below it, so check your transformer's minimum load rating before you buy.

Can I put it on a dimmer switch?

No. It is not dimmable, so it belongs on a circuit with an ordinary switch. That rules out a dimmer wired ahead of the transformer too, because it still varies the supply reaching the bulb.

Why do the LEDs look yellow when it is a cool white bulb?

The yellow is the phosphor coating on each LED, which is how most white LEDs are made. The coating converts part of the blue light from the chip beneath, and the mix comes out white, so once it is switched on the bulb gives 4000K light.

How bright is this bulb?

It gives 140 lumens from 1.2W, spread over a 120° beam. If your old bulb lists its lumens, compare the two figures; if it only lists watts, that tells you how much power it used, not how much light it gave.

Can I use it in a bathroom or outdoors?

The maker states no place of application for this bulb, so we cannot tell you it is suitable for a bathroom, an outdoor fitting or anywhere damp, and we would rather not guess.
