OUT WITH THE OLD, IN WITH THE NEW – T8S MAKE WAY FOR LED BATTENS

T he first fluorescent lamp was introduced in 1939, and for decades it was hailed as an almost universal solution to lighting spaces efficiently and economically. In 1981, the 32 W T8 lamp was introduced in the United States, providing further improvements in four-foot fluorescent lamps, and it became the standard for new construction. Available in a variety of linear and U-shaped config- urations, millions were installed across the globe in

make for easy and quick installation. The LinearPac LED anti-corrosive is popular for car parks, service areas, warehouses and retail applications and comes with a five-year warranty. With an efficacy of up to100 lm/W, it creates the necessary lighting levels while providing the desired energy savings. The vandal-resistant polycarbonate body comes supplied with anti-tamper stainless steel clips and the diffuser is permanently attached for ease of installation. Both fittings offer a microwave sensor detector option which works up to 12 m, has an IK08 impact rating and the all-important 1.5 kV surge protection is built in.

the quality of lighting for end-users in and around their buildings.” Two IP65 rated robust fittings from the Enlite range of linear anti-corrosive LED battens have been engineered with energy saving and longevity in mind. Both are suitable for interior and exterior usage and in the most challenging of environments. They enable T8 fluorescent fittings to be replaced with LED as budgets permit on a one-for-one basis, providing the wiring is still in good condition. The anti-corrosive UniPac range is vandal-resistant as it’s formed from a single polycarbonate body and uses high lumen LED chips and an opal diffuser to provide smooth even light distribution with no ‘hot spots’. The UniPac is an IP65 sealed linear fitting with a three-year warranty. Push-fit terminals at both ends

a countless number of applications from basements to bathrooms. However, since advancements in LED technology, this valiant workhorse has been superseded for two reasons; it is energy hungry and its lighting efficacy can’t compete with modern alternatives. South Africa faces particular challenges. “All businesses are under pressure to attain energy savings but this costs money,” says Warwick Webber,

managing director of Aurora in South Africa, “so it’s our job as a manufacturer to provide solutions that can pay for themselves in the short term, offer ongoing energy savings thereafter while improving

provide the visitor with an overview of the background, course, impact and suffering caused by the Anglo-Boer War that was fought between the two Boer Republics of the Transvaal and the Orange Free State and Great Britain from 1899 to 1902. The War Museum has the largest collection of Anglo- Boer War related objects and memorabilia in the world. Museums are a communication link to fill the gap between generations by sharing knowledge with different communities. They serve as a mediator to help current and future generations embrace history and acknowledge the existence of those who came before them. Museums play a huge role in ensuring understanding and appreciation for various cultures while preserving heritage by protecting, conserving and displaying artifacts from the past. There is more to a museum than what it displays. It is an institution where research is conducted, collections are stored. It is a forum in which aspirational and educational experience takes place. It therefore needs an appealing and interesting appearance and that is where lighting plays an important role. Lighting enhances the impact of items on display creating a connection between generations. BEKA Schréder locally develops and manufactures LED lighting products, designed and suitable for local conditions. BEKA Schréder is proud to be associated with FCE Consulting Engineers in providing a successful LED lighting solution for this project.

BEKA Schréder, a leading local manu- facturer of LED luminaires, has supplied a decorative LED lighting solution to the Anglo-Boer War Museum in Bloemfon- tein and the Garden of Remembrance, which was recently added to the outdoor exhibit area. The Garden of Remembrance was established to specifically honour the women and children who died in concentration camps – and in the field – during the Anglo-Boer War between 1899 and 1902. The names of the deceased are inscribed in alphabetical order on the walls, which are lit with BEKA’s linear LED luminaires, creating an appropriately dramatic effect to the memorial. As part of this addition, new walkways linking the Garden of Remembrance to the National Women’s Memorial were built. The walkways are illuminated with BEKA Schréder’s LEDpost LED bollard luminaires

that provide elegant low- level orientation lighting that welcomes visitors from across the globe. The lighting was installed not only to improve visibility, security, and aesthetics but to highlight the value of the museum for generations to come. The War Museum’s seven display halls with their unique exhibits and dioramas, as well as the numerous outside exhibits,

Lighting and motion management systems – an all-round win-win solution

L egrand’s lighting and motion management systems encom- pass a wide range of sensors de- signed to make buildings more energy efficient by automatically reducing the amount of time lighting is left on un- necessarily. “Reduced lighting consumption not only lowers operating costs, but also reduces lamp replacement and maintenance requirements and helps decrease Green House Gas (GHG) emissions,” says Sonja Leibbrandt, marketing and pricing manager, Legrand South Africa. Lighting management sensors are suitable for areas of a building with or without natural light, including passages, corridors, hallways, staircases and restrooms and also for offices, storage rooms and warehouses. These sensors are also available with advanced features for installation outdoors and in humid

areas of domestic, commercial and industrial buildings. Sensors Sensors for controlling a single circuit in outdoor and damp areas with natural light, have an IP55 index protection rat- ing to guard against the ingress of dust and water. These sensors, with three wires and neutral, have an automatic switch on/off occupancy mode set- ting and switch off automatically when there is sufficient natural light in the area. There is an adjustable time delay between 5 s and 59 minutes and a light level threshold from 5 to 1 275 lux. Lighting sensors for controlling a single circuit in outdoor and damp areas without natural light are fitted with automatic on/off controls, manual adjustment of the light level threshold and time delay via a potentiometer. Legrand’s lighting management

solutions for outdoor areas and humid areas also includes sensors for managing multiple circuits. For more information about this product, visit www.legrand.co.za
