Wide beam for more even lighting

Thanks to its 320° angle, this bulb emits light almost all around, making it especially suitable for open or semi-open fixtures: pendants, wall sconces, globes, portholes, or decorative lamps. The result is more uniform, with fewer shadowed areas and a more enveloping light.

Direct replacement without installation changes

The A60 shape and E27 base allow immediate replacement in existing installations. This is an efficient solution for maintenance teams, multi-site operators, and professionals who want to quickly standardize their inventory without technical modifications.

• Remove the old bulb.
• Direct replacement with E27.
• Power on test and socket retention check.

Low power, good light output

With 840 lm for 4W, this bulb offers an excellent flux-to-consumption ratio. It is an effective alternative to old incandescent lamps of about 60W, while helping significantly reduce energy costs in installations with many light points.

Compatibility and usage precautions

This LED filament bulb is suitable for 220–240V installations. To preserve its lifespan, it is recommended to check the thermal compatibility of the fixture, especially in fully enclosed or poorly ventilated devices.

⚠️ Pro Safety: always cut power before handling and avoid overly confined or poorly ventilated environments, which can accelerate heating and reduce the source’s lifespan.
