Description
This is a G9 capsule LED, the small two-pin lamp with a looped wire base that pushes straight into its holder rather than twisting or screwing in. It draws 4.2W and gives 470 lumens, which the pack puts against a 40W halogen capsule. The light is 2700K warm white, the warmer end of white light, with the yellow-amber cast people expect from a halogen lamp rather than the flatter look of a 4000K or 6500K bulb. The clear housing lets the individual LED chips read as bright points behind it, and the quoted beam angle of 300 degrees means light leaves almost the whole body rather than firing forward in a cone.
G9 holders turn up in several places at once: multi-arm pendants, wall lights, cooker hood lamps, plinth and shelf fittings, and small table lamps where the shade sits close to the lamp. Because the capsule is compact and the output is spread so widely, it suits fittings with several lamps behind glass or fabric, where an even glow matters more than a directed beam. Check the holder before ordering: G9 and G4 look alike at a glance, but G9 pins sit 9mm apart and run on mains voltage, while G4 pins are 4mm apart and usually run at 12V through a transformer.
There is no dimming here. The spec lists it as non-dimmable and the pack carries the crossed-out dimmer icon, so wire it to a plain switch. The energy rating is E, and the pack prints a 15 year lifespan. Each unit is one boxed bulb, and the minimum order is 12, sold in multiples of 12, which suits a multi-arm fitting or keeping spares in the drawer.

Frequently Asked
Will this fit my existing G9 holder?
Yes, if the old lamp has two stiff looped wire pins set 9mm apart. Pull the old capsule straight out and push this one straight in, with the power off and the lamp cool.
How do I tell a G9 from a G4 before I order?
G4 pins are straight, 4mm apart and normally fed at 12V from a transformer. G9 pins are looped, 9mm apart and run at mains voltage, so the two are not interchangeable.
Can I use it on a dimmer switch?
No. The specification lists it as non-dimmable and the pack shows the crossed-out dimmer icon, so it needs a plain on and off switch to work properly.
How bright is 470 lumens for this size of lamp?
It is the output the pack matches to a 40W halogen capsule, so a fitting holding three or four of them gives a well lit room rather than only accent light.
What does 2700K actually look like once it is in?
Warm and slightly yellow, close to the old halogen capsules, which matters if the fitting holds several lamps and you are replacing only one of them.
Is an IP rating given for this lamp?
The manufacturer states no IP rating, so treat it as an ordinary dry indoor lamp and fit it only where the holder itself is rated for the location.
