Description

The E27 T38 Filament LED Bulb 25W 5250lm High Efficiency 210/m W for Public Lighting Class A is an advanced solution for street lighting that effectively replaces old sodium vapour lamps, offering efficient lighting with minimal energy consumption. Its LED filament design with an E27 base allows for easy integration into streetlights and urban fixtures without the need for modifications, ensuring a quick and cost-effective installation.

Maximum Efficiency and Energy Savings

With an impressive luminous efficiency of 210 lm/W, this bulb generates a luminous flux of 5250 lumens while consuming only 25W. This grants it the prestigious Class A energy rating, ensuring significant savings compared to traditional technologies. Its LED filament technology optimises light distribution, reducing losses and improving uniformity in street lighting.

Colour Temperature Adapted to Each Environment

This bulb is available in three colour temperatures to suit different environments and lighting needs. Its 1800K version (super warm) is ideal for rural areas or urban centres where a light similar to that of old sodium vapour lamps is desired, minimising light pollution and reducing environmental impact on nocturnal wildlife. The 3000K (warm) option is perfect for urban settings that require a welcoming illumination with a more natural colour rendering. For spaces where optimal visibility and realistic colour perception are essential, the 4000K (neutral) version is available, mimicking sunlight to provide maximum brightness.

Compliance with Light Pollution Regulations

In many European countries, legislation requires public lighting in urban areas to use warm light sources to reduce light pollution and minimise the impact of blue light on the environment. This bulb has been designed to meet these regulations, providing efficient and environmentally friendly lighting. Its light spectrum favours optimal visibility without glare, ensuring both visual comfort and the protection of nocturnal biodiversity.

Sustainable Solution for Urban Lighting

As a next-generation LED alternative, this bulb not only improves the energy efficiency of public lighting but also reduces maintenance costs thanks to its long lifespan. Its compatibility with traditional E27-threaded fixtures allows for the modernisation of existing infrastructures without the need for costly adaptations, facilitating the transition to more efficient and sustainable lighting.
