LEDbulb ND 4.9-40W A60 E27 840 1CT 929003564147

Universal high energy efficiency LED light source

The LEDbulb ND 4.9W LED bulb with an E27 base is a modern lighting solution in a traditional A60 shape, allowing for easy modernization of existing fixtures without the need to replace the entire system. Thanks to a color temperature of 4000K (neutral white), it provides comfortable lighting in various spaces.

Operating parameters and energy efficiency

The device generates a luminous flux of 470 lm with a luminous efficacy of 95 lm/W, making it an efficient replacement for a traditional 40W bulb. A color rendering index of CRI 80 guarantees natural color reproduction, while a wide beam angle of 180° ensures even light distribution throughout the room.

The bulb operates within a standard voltage range of 220-240V with a power factor of 0.54, resulting in stable operation in typical domestic and commercial installations. The design allows for operation in ambient temperatures from -20°C to +45°C, expanding application possibilities both indoors and outdoors.

Construction, durability, and safety of use

The body made of high-quality plastic provides mechanical resistance while maintaining a low mass. The IP20 protection rating protects against finger contact and access to hazardous parts, which is sufficient for standard indoor applications.

LED technology eliminates the emission of UV and IR radiation while significantly reducing heat emission compared to incandescent sources. This feature protects temperature-sensitive objects and reduces the load on air conditioning in rooms.

Practical applications and economic benefits

Thanks to a long lifespan of 10 000 hours and the ability to perform up to 50 000 on/off cycles, the light source minimizes maintenance and replacement costs. It is particularly effective in frequently used areas such as receptions, lobbies, or hotel corridors.

A low flicker level ensures visual comfort and eye safety during prolonged stays in the illuminated room. In restaurants, it creates a friendly atmosphere for guests while simultaneously reducing operating costs by up to 80% compared to traditional bulbs.

The lack of a dimming function simplifies installation and eliminates the need for additional controllers, translating into low investment costs while maintaining high energy efficiency of class F.
