Built for tight spacesThis
G4 bi-pin LED capsule belongs to a compact lamp family designed to slip into sockets where nothing else fits. With a body of just
0,52 in in diameter and
1,7 in overall length, it drops into the same cavity your old halogen capsule occupied — cabinet pucks, low-voltage sconces, chandelier arms, display shelves and accent heads. Because it's solid-state, it shrugs off frequent on/off switching, and it runs far cooler than a halogen capsule, which matters when the lamp sits inches from wood shelving, fabric shades or food displays.
Light quality you can trustThe high-lumen design pushes
300 lumens from only
2,5 W, matching the output of a
30W halogen capsule. A
CRI ≥80 keeps skin tones, textiles, wood grain and packaging looking natural rather than washed out, and the
360° beam angle spreads light evenly through diffusers and glass shades instead of creating a single glaring dot. The
4 000K neutral white is the go-to choice for kitchens, bathrooms, retail displays and workspaces where you want clarity and contrast rather than a yellow cast.

Installation and compatibilityInstallation takes seconds: cut the power, pull the old capsule straight out, and push the new pins into the
G4 socket. Handle the lamp with clean hands or a soft cloth to keep oils off the body. Since this is a
12V low-voltage lamp, confirm your transformer or LED driver is rated for LED loads — some older magnetic transformers need a minimum load to start and run properly, which can cause flicker with very low-wattage lamps. For dimming, pair the lamp with a dimmer and driver that are listed as compatible with low-voltage LED loads for smooth, flicker-free control. Remember that this model is not rated for fully enclosed fixtures or damp locations, so keep it in open or ventilated housings in dry areas.
Applications, related lamps and documentationThink under-cabinet and in-cabinet lighting in a kitchen renovation, glass jewellery cases in a boutique, sconces in a hotel corridor, or a decorative chandelier in a dining room where a dozen tiny lamps used to run hot.
