Đèn LED COB G9 3W 4W 5W …

The G9 halogen capsule was the bulb that made small decorative fittings possible and the electricity bill painful: 25 to 40 watts of heat in a capsule the size of a thumb, burning out on a schedule. The ILED-BL60-A A replaces it like for like — a glass COB G9 that runs the same socket at a fraction of the power and holds the compact size the fittings were designed around.

The three outputs

The 3W runs 280 to 300 lumens from a 49×13mm glass body, which is the shortest of the three and suits the fittings with tight space behind the capsule. The 4W runs 380 to 400 lumens from 60×13mm. The 5W runs 480 to 500 lumens from 60×16mm, and it is the output that replaces the brighter 33W and 40W halogen capsules. All three run a COB chip behind glass, so the light reads as one even capsule rather than a ring of dots, which matters in the fittings where the capsule is visible through glass.

The COB and the glass

Two build choices separate this bulb from the cheaper G9 LEDs. The chip is COB — one chip, one even light surface — rather than a cluster of SMD points, so the light through a glass shade or a crystal drop stays smooth. And the body is glass rather than plastic, which keeps the capsule looking like the halogen it replaces and handles the heat the way a small enclosed fitting expects. Colour runs in two bins: 2700-3000K warm white and 6000-6500K cool white, chosen per room rather than mixed in one fitting.

Voltage and fitting

The bulb runs direct on 220V or 110V, so it suits the European, Australian and North American fittings without a transformer. Check the fitting’s maximum bulb length before ordering the 4W and 5W, because the 60mm bodies are longer than the 49mm 3W, and an enclosed capsule holder has less room behind the glass than it appears. The two colour bins ship separately, so a fitting that needs warm white takes the 2700-3000K version and a fitting that needs cool takes the 6000-6500K version — order them against the room, not against the socket.

Flicker

The product is built without stroboscopic flicker, which is the other reason it replaces the halogen cleanly. In a chandelier of G9 sockets — the dandelion forms, the crystal rings, the multi-arm fittings — a bulb that flickers shows at every drop, and one that does not keeps the room calm on camera and to the eye.

Nơi được sử dụng

Chandeliers and decorative fittings with G9 sockets, where the capsule is visible and the glass body matters. Crystal and glass fittings, where the COB’s even light keeps the sparkle clean. Kitchen and bathroom cabinet fittings on 220V or 110V circuits. And anywhere a G9 halogen is still burning — the socket is the same, the switch is the same, and the power draw drops to a fraction from the first switch-on.

Swapping the halogens out

The swap is the simplest upgrade in lighting: switch off, pull the halogen capsule, push the G9 LED in, switch on. No transformer to replace, no driver to rewire, no fitting to modify. Two practical checks before ordering — the length of the bulb against the space behind the fitting’s glass, and whether the fitting runs a dimmer, because the specification does not list dimming for this bulb and a non-dimmable bulb on a dimmer circuit misbehaves. For the fittings without a dimmer, the swap is a same-afternoon job across a whole chandelier, and the heat the old capsules pushed into the room disappears with them.

Why do buyers pick the ILED-BL60-A A over the alternatives? Here is what we hear from customers:

Like-for-like halogen replacement. Same G9 socket, same capsule look, a fraction of the power and the heat. The fittings keep their glass, the switch keeps its job, and the power draw drops from the first switch-on.

COB behind glass. One chip behind a glass body gives an even capsule of light rather than a ring of dots, which is what the visible-capsule fittings — the crystal chandeliers and the glass shades — need.

Three outputs, three lengths. The 3W short body fits the tight holders, the 4W is the all-rounder, and the 5W replaces the brighter halogens. The lengths differ, so check the fitting’s space before choosing.

Two colour bins, chosen per room. 2700-3000K warm white for dining and living, 6000-6500K cool white for working positions, matching the colour the halogens or the fittings already run.

No stroboscopic flicker. In a chandelier with a dozen G9 sockets, flicker shows at every drop. This bulb runs steady on camera and to the eye.

The ILED-BL60-A A goes wherever a G9 halogen is still burning, and into the new fittings that spec G9 sockets for their compact size.

Crystal chandeliers and multi-arm fittings. A dozen G9 sockets over the dining room, each capsule visible through the drops. The COB’s even light keeps the sparkle clean, and the power draw of the whole fitting drops to a fraction of the halogen load.

Glass and enclosed decorative fittings. Where the capsule sits behind glass or in a tight holder, the 49mm 3W body and the glass construction keep the fitting looking and running as designed.

Kitchen and cabinet fittings. Under-cabinet and over-counter G9 positions on 220V or 110V circuits, with the cool-white bin for working surfaces and the warm bin for the evening room.

Hospitality retrofits. Restaurants and hotels running halogen G9s on long hours, where the bulb swap pays for itself in weeks and removes the ladder-and-glove cycle of replacing hot, short-lived capsules.

Shop and display fittings. G9 spots and linear fittings over the merchandise, where the two colour bins let the display hold the colour the stock needs without changing the fitting.
