E27 ST64 4W Filament LED Bulb

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

Technical details

E27 base, direct connection to 220 - 240V, 50-60Hz. Power consumption of 4W for 360 lumens, or 90 lm/W, equivalent to a 40W incandescent bulb. Color temperature 2700K, color rendering index Ra 80, 360° beam angle. Amber glass ST64 bulb, 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 for high-density arrangements of light sources without exceeding visual comfort luminance levels, while retaining the visual profile of a large Edison tube. Non-dimmable model: do not use a dimmer on the circuit. CE & RoHs compliant, 2-year warranty.

Installation

Isolate the circuit before installation, then screw the bulb into the E27 socket. No transformer or additional equipment is required. For string lights or light rails, check that the combined wattage is compatible with the rating of the circuit's protective device. Full output is reached as soon as the bulb is switched on, with no warm-up time.

Where can you use this LED bulb?

Counter rails, indoor decorative string lights, multi-pendant fixtures above tables, display windows, back bars, and circulation areas in hospitality venues. Also suitable for hotel and retail settings where ambiance takes priority over general illuminance levels.
