The pack of 10 dimmable amber C37 E14 4W filament LED bulbs meets the needs of a full chandelier or a row of wall lights: ten dimmable bulbs on the same dimmer, with no color differences between them.

Specifications per bulb

Each bulb uses 4W and produces 360 lumens, equivalent to 90 lm/W and a 40W incandescent bulb, with a 360° beam angle. Warm white, color rendering index Ra 80. The C37 flame-shaped bulb measures 3.5 cm in diameter and 9.8 cm in height. IP20 rating, operating range from -20°C to +40°C, estimated lifespan of 25,000 hours.

Dimming and dimmer compatibility

Brightness can be adjusted using a TRIAC dimmer (AC phase-cut dimming), a technology used by most wall dimmers on the market. Two points to watch with a multi-bulb installation: the dimmer must be rated as compatible with LED loads, and its minimum load requirement must be met—ten 4W bulbs add up to 40W, which is still low for some older models designed for incandescent bulbs and may cause flickering at the lower end of the dimming range.

Installation

Switch off the circuit, screw the bulbs into E14 sockets, then switch the power back on. No transformer or accessories are required; the bulbs connect directly to the 220-240V mains supply. Without a dimmer, they work normally at full power.

Benefits of the 10-pack

All ten bulbs come from the same batch: they respond identically to dimming and maintain the same amber intensity at the lower end of the range, which matters on a crystal chandelier where the bulbs are visible side by side. This pack size makes it easy to replenish decorative lighting installations. CE & RoHs certified, with a 2-year warranty.
