Amber Smart Wifi LED Filament Bulb E27 4W ST64 CCT - 2700K/6500K - Pack of 10

The pack of 10 connected Wi-Fi LED filament bulbs, E27, 4W, amber ST64 CCT combines the elongated shape of an Edison bulb with an adjustable color temperature, for installations where several visible light sources need to change together throughout the day.

Specifications per bulb

Each bulb uses 4.2W for 400 lumens, or 95 lm/W, equivalent to a 42W incandescent bulb, with a 360° beam angle. The CCT function continuously covers the 2700K to 6500K range, with a color rendering index of Ra 80. The amber glass ST64 tube measures 6.4 cm in diameter and 14.3 cm in height. Energy class F, IP20 rating, operating range -20°C to +40°C.

Multi-point control and management

The 2.4 GHz Wi-Fi module connects directly to the router: no gateway or hub is needed. The 5 GHz band is not supported, so the 2.4 GHz network must be selected during pairing. The L Silumen Home app, also compatible with Tuya Smart and Smart Life, lets you create groups to control all ten bulbs at once: on/off, brightness from 1 to 100%, color, scheduling, scenes, and sharing across multiple accounts. Voice control with Alexa, Google Assistant, and Siri. Dimming is software-based; no phase-cut dimmer should be installed upstream.

Installation

With the circuit switched off, screw the bulb into an E27 socket, switch the power back on, then pair it. It connects directly to the mains, without a transformer. Ensure sufficient Wi-Fi coverage where the light fixtures are installed, especially with high-hanging lights or metal suspended ceilings.

Benefits of the pack of 10

The batch comes from the same production run: the shade remains consistent from one socket to the next, a decisive factor when the bulbs are lined up above a counter or dining table. The packaging also makes bulk restocking easier. CE & RoHS certified, with a 2-year warranty.
