LED Filament Bulb E27 4W ST64

4W ST64 E27 LED filament bulb

Use more light sources rather than concentrating the output: this is the principle behind decorative installations with repeated light sources, where excessive wattage per bulb causes direct glare. This 4W version of the ST64 tube delivers 360 lumens of warm white 2700K light, designed for counter bars, string lights and multi-pendant lights.

Technical details

E27 base, direct connection to 220 - 240V, 50-60Hz. 4W power consumption for 360 lumens, or 90 lm/W, equivalent to a 40W incandescent bulb. 2700K color temperature, color rendering index Ra 80, 360° beam angle. Amber ST64 glass envelope, 6.4 cm in diameter and 14.3 cm high, identical to the 8W model. Energy class F, IP20, rated lifetime of 25,000 hours, operating range -20°C to +40°C.

Features

The low output per bulb allows high-density installations without exceeding comfortable luminance levels, while retaining the visual profile of a large Edison tube. Non-dimmable: do not use a dimmer on the circuit. CE and RoHS compliant, with a 2-year warranty.

Installation

Isolate the circuit before installation, then screw the bulb into the E27 socket. No transformer or additional control gear is required. For a string light or bar, check that the combined wattage is compatible with the circuit breaker's rating. Full rated light output is available as soon as the bulb is switched on, with no warm-up time.
