COB G4 LED Light 3W 4W 5W

The G4 halogen capsule lives in the fittings where the bulb is smallest and the work is hardest: the crystal chandeliers, the cabinet displays and the picture lights where a dozen capsules burn inside glass and metal for hours at a time. The ILED-BL60-A B replaces it like for like — a glass COB G4 on the same small pins, running a fraction of the power at the same compact size.

The three outputs

The 3W runs 280 to 300 lumens from a 49×13mm glass capsule, the size that suits the tightest holders. The 4W runs 380 to 400 lumens from 60×13mm. The 5W runs 480 to 500 lumens from 16×60mm, and it covers the brighter capsules in the larger multi-arm fittings. The three share the same pins and the same two colour bins, so a chandelier can mix outputs per position — brighter over the table, softer at the edges — while the capsules still read as one design. All three run a COB chip behind glass, so the capsule reads as one even light surface rather than a ring of dots — which is what the crystal and glass fittings need, because the capsule sits exposed inside them.

The COB and the glass

Two build choices separate this bulb from the cheaper G4 LEDs. The chip is COB — one chip, one even field — rather than a cluster of SMD points, so the light through crystal drops and glass shades stays smooth, and the sparkle reads from the crystal instead of from the LEDs behind it. The body is glass rather than plastic, which keeps the capsule looking like the halogen it replaces and handles the heat in the small enclosed holders the G4 socket usually lives in. Glass also stays clear over years behind crystal and glass shades, where some plastics cloud and dull the sparkle the fitting was bought for.

Voltage and fitting

The bulb runs direct on 220V or 110V, so it suits the European, Australian and North American fittings without a transformer. Two practical checks before ordering: the length, because the 60mm bodies are longer than the 49mm 3W and the small G4 holders vary in the space they leave behind the crystal; and the colour bin, because the 2700-3000K warm white and the 6000-6500K cool white ship separately and a fitting looks wrong with both mixed.

Where it gets used

Crystal chandeliers and wall lights with G4 sockets, where the capsule is visible through the drops. Cabinet and display lighting, where the small capsule fits the profile and the COB keeps the merchandise lit evenly. Picture lights and over-mirror fittings, where the capsule sits close to the glass and the glass body handles the enclosed heat. And anywhere a G4 halogen is still burning — the pins are the same, the switch is the same, and the heat and the power draw drop from the first switch-on. For a chandelier of twelve sockets, that is the difference between a fitting the household switches freely and one the family leaves off because the room it heats is not the room they are in.

Swapping the halogens out

The swap is a same-afternoon job across a whole chandelier: switch off, pull each halogen capsule, push the G4 pins in, switch on. No transformer to rewire inside the chandelier body, no driver to find a home for, no fitting to modify. Two checks before ordering — the length of the bulb against the space behind the drops, 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 heat the old capsules pushed into the room and onto the crystals disappears with them, and the crystal stays cooler and cleaner between cleans.

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

Like-for-like G4 replacement. Same small pins, same glass capsule look, a fraction of the power and the heat. The crystal fitting keeps its capsule, 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, which is what the exposed positions — crystal chandeliers and glass shades — need. SMD bulbs show their dots there.

Three outputs, three lengths. The 3W short body fits the tight holders, the 4W is the all-rounder, and the 5W replaces the brighter capsules in the bigger fittings. Check the length against the holder before choosing.

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

Direct on 220V or 110V. No transformer to hide inside the chandelier or the cabinet; the bulb runs from the supply the fitting was built for.

The ILED-BL60-A B goes wherever a G4 halogen is still burning, and into the crystal and cabinet fittings that spec the small-pin socket for their size.

Crystal chandeliers and wall lights. A dozen G4 sockets behind the drops, each capsule visible through the crystal. 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.

Cabinet and display lighting. Under-cabinet and in-cabinet G4 positions, where the small capsule fits the profile and the glass body survives the enclosed holder.

Picture lights and over-mirror fittings. Where the capsule sits close to the glass and the COB’s even field keeps the artwork and the mirror lit without the dotting an SMD bulb shows.

Hospitality retrofits. Hotels and restaurants running G4 halogens on long hours inside the chandeliers and the wall fittings, where the swap pays for itself in weeks and removes the short-life capsule cycle.

Shop and display fittings. Small G4 spots over the merchandise, with the two colour bins matched to the stock rather than mixed inside one fitting.
