Amber LED Filament Bulb E27 4W ST64 - Pack of 10

The 10-pack of 4W amber ST64 E27 LED filament bulbs features the 14.3 cm Edison tube with deliberately reduced light output: 360 lumens per bulb, designed for installations where you add more light sources without increasing glare.

Specifications per bulb

Each bulb uses 4W for 360 lumens, or 90 lm/W, equivalent to a 40W incandescent bulb, with a 360° beam angle. Rich amber warm white, color rendering Ra 80. The ST64 tube has the same dimensions as the 8W model: 6.4 cm in diameter and 14.3 cm tall. Energy class F, IP20 rating, operating temperature range from -20°C to +40°C, estimated lifespan of 25,000 hours. Non-dimmable model; do not connect to a dimmer.

Sizing a multi-point installation

On a string of lights, a multi-arm pendant or a counter rail, ten 720-lumen bulbs often flood the space. The 4W version keeps the same tube shape while cutting the light output in half, for a total of 3,600 lumens distributed across ten points instead of 7,200. Total power consumption drops to 40W. This is a choice for setting the mood rather than general lighting.

Installation

With the power off, screw into an E27 socket, then switch the power back on. No transformer or accessories required; connects directly to the mains and reaches full brightness as soon as it is switched on.

Benefits of the 10-pack

The ten units come from the same production run: the amber tint stays consistent from one socket to the next, which is precisely what matters in installations where several tubes are visible side by side. CE & RoHS certified, with a 2-year warranty.
