BEKA Schréder’s solar- powered LED street lights increase quality of life for Ditloung’s residents.

FIVE ESSENTIAL LIGHTING TESTS IN 30 SECONDS

SOLAR-POWERED STREET LIGHTS FOR THE DITLOUNG COMMUNITY

The slim, aesthetical design is optimised for LED characteristics. BEKA Schréder locally develops and manufactures LED lighting products, designed and suitable for local conditions.

BEKA Schréder has supplied a solar-pow- ered LED street lighting solution for Dit- loung, a small community situated in the Northern Cape Province near Olifants- hoek. Ditloung’s busiest roads are now illuminated at night, owing to the involve- ment of Renewable Energy Investments South Africa (REISA), and the May- or and Electrical Department of the Gamagara Local Municipality. In addition to the well-being of more than 10 200 residents, the initiative aims to improve community safety and security. The environmentally friendly so- lar-powered LED street lighting in- stallation requires almost no main- tenance and zero running costs. The LEDlume-mini 16LED/36 W luminaire, mounted at 8 m above road level, was chosen for this pro- ject. The solar panels and battery boxes are secured by tamper-proof screws to prevent theft. Further- more, the BEKA Schréder solar module has been engineered for all geographical locations in Africa, and has been designed to operate reliably at a high light output over a 12 to 14 hour period. It has suf- ficient autonomy to cater for up to two continuous overcast or rainy days, in order to continue its reliable night operation. The LEDlume-mini is designed and manufactured in South Africa and thus takes Africa’s environments and conditions into account. This is evident in the luminaire’s design. A unique thermal sensor technique monitors the temperature of the LEDs on the printed circuit boards (PCBs). Once a critical temperature is reached, which could harm the lifetime of the LEDs, the current is reduced to ensure safe operating temperatures of the LEDs. This safeguards the LEDs and ensures that the long lifetime of up to 100 000 hours (L70), is achieved.

B uilding maintenance technicians for commercial, retail, or institutional facilities with fluorescent lighting, have hundreds, if not thousands of fluorescent tubes that have to be routinely checked and maintained. Even though the tubes last for tens of thousands of hours, they do ultimately fail, some prematurely, and some stop working because of other problems with the installation ballast. In the past, this type of maintenance has usually meant lots of trial and error. And if a lamp was found to be out, the technician would have had to climb a ladder, open up the cover, remove the tube and replace it. If the new tube didn’t light, the technician either tried again, had to call an electrician or bring out a voltage tester. Fluke has developed a tool that takes the trial and error – and a significant amount of time – out of maintaining fluorescent lighting. The Fluke 1000FLT fluorescent light tester specifically designed for building maintenance professionals is an all-in-one fluorescent lamp tester, ballast tester, non- contact voltage tester, pin continuity tester, and ballast-type discriminator. Instead of having to carry two or three testing tools, the Fluke 1000FLT fluorescent light tester is able to make all of the following measurements: • Lamp test: Allows testing without removing the tube from the ballast. The tester sends a pulse of energy that lights up the tube if there is gas in it. The Fluke 1000FLT fluorescent light tester is compatible with T5, T8, and T12 fluorescent tubes. • Ballast test: Determines whether the ballast is working. • Non-contact voltage test: Checks for the presence of voltage without touching the source. • Pin continuity test: Tests whether filaments in the tube have continuity. • Ballast-type discriminator: The Fluke 1000FLT fluorescent light tester is the first multi-function tester to include this feature, allowing techni- cians to easily identify whether the ballast is electronic or magnetic without taking the fixture apart or even climbing a ladder. The tester is aimed at the ballast from the ground and it immediately identifies if the tube is the old-style, power-hungry magnetic ballast, for maintenance or replacement. The Fluke 1000FLT fluorescent light tester's user interface was designed to be as simple as possible, with all tests delivering instant results. The ballast, voltage, and pin continuity tests indicate results with ‘Go’ or ‘No Go’ indicator lights. The ballast-type discriminator lights up either the ‘magnetic’ or ‘elec- tronic’ LED on the face of the tester, while the lamp test result is determined by the user if the tube lights up or not. ACDC Dynamics’ illumination wire, cable piercing connectors and com- prehensive range of B22 lamps will provide a decorative lighting solution for the fast approaching festive season. The handy little lighting kit can be used to easily install a decorative lighting effect, in any area. The lamps can be as close or spread out as you need, and there is no need to change any of the equipment in use. ACDC DYNAMICS’ ILLUMINATION WIRE Enquiries: www.comtest.co.za
