1. New lighting concept NARVA DT-T8 LED tubes in Brand-Erbisdorf primary school

2. NARVA LED retrofit tubes are a professional high-quality replacement for fluorescent lamps. These tubes are designed for temperatures ranging between -20 and +40°C, and extend far beyond ambient lighting in application due to their excellent luminous flux values. Brand-Erbisdorf primary school for general education has the following mission statement: Learning together – with heart and mind The school’s aim is to teach children a self-assured, socially aware and independent approach to life. The school has 325 children in 14 classes from grades 1 to 4. The Town of Brand-Erbisdorf together with the school and NARVA planned new lighting concept as part of a regional Saxon energy management initiative. DT-T8 Retrofit LED tubes were selected to save energy and improve lighting conditions in the classrooms and common rooms.

3. The new DT-T8 Retrofit tubes were installed in classrooms, school cabinets and common rooms. Most of the work takes place in the classrooms, with desks and chairs arranged according to the type of work. The aim was to plan the lighting for any furniture arrangement. Proper light distribution and even lighting intensity prevent glare, making any type of visual work easier, especially enabling a clear view of the board in front of the class. The DT-T8 Retrofit tubes feature especially even light emissions and excellent luminous flux values; their high switching capability makes them very robust, and they are also compact and impact-resistant due to the polycarbonate material used. Energy savings and up to three times the life time of conventional fluorescent lamps make these LED tubes an attractive lighting alternative.

4. The old lamps in the corridors of the school were also replaced by new LED lamps. Before the upgrade: The corridors in the school were dark and poorly illuminated. After the upgrade: The corridors are bright and illuminated. The new light colour 840 was used here.

5. Upgrade: Town of Brand-Erbisdorf, Bauhof municipal building yard Before: LT T8 58W; 36W; 18W LF 830 Upgrade: NARVA LED DT-T8 Retrofit tube, LF 840 28.5W; 23W; 11.5W Benefits of the new lamps: - High-quality industrial-grade replacement for fluorescent tubes in the T8 range - Especially homogeneous luminous emittance - Reduced light scatter and glare - More than 50% energy saving compared to fluorescent tubes - Ideal for difficult maintenance situations - Adjustable standard socket for optimising the lighting alignment from the LED tube

6. Brand-Erbisdorf Elementary School Result of upgrade: Improved lighting conditions More eye comfort Energy savings Fast return on investment Even light distribution Homogeneous lighting Stable photometric properties Long lifetime in lamps Cost savings: Lights on 220 working days per year Average 5 h per day Power savings at more than 50%
