According to energy specialist Rhino Lighting, replacing compact fluorescent lighting (CFL) with new-generation LED luminaires can result in a reduction in lighting energy costs of up to 50%, with halogen replacement savings being as high as 90%.

The company’s installation of SA-manufactured LED lighting at the Newton Park Swimming Pool in Port Elizabeth has resulted in a 50% reduction in the centre’s monthly lighting bill.

In industrial settings, LED lamps have also been proven to have a longer lifespan and additional benefits such as lower maintenance, improved longevity, mercury-free components and reduced greenhouse gas emissions mitigate any initial higher outlay.

However, Rhino Lighting managing director Heather McEwan cautions that not all LED lighting options are created equal.

“Cheap, foreign imports have flooded the local market and damaged the reputation of LEDs,” said McEwan. “Fortunately, South African manufacturers are rising to the challenge and producing good quality, locally made luminaires.” Buying locally manufactured lighting also ensures that after-sales support is available.

Aside from quality issues, however, consumers also run the gauntlet of old-school technologies, McEwan said.

“New generation LEDs make old-school versions look outdated and consumers need to make informed choices when selecting their lighting.”

She said lighting fixtures were particularly vulnerable to voltage fluctuations as a result of Eskom’s “dirty power” supply and that new-generation LEDs featured built-in integrated constant current regulation, or so-called “driverless” technology to manage this.

Rhino Lighting sources South African-manufactured LED luminaires with driverless technology. The built-in protection unit protects the luminaire against premature failure owing to voltage spikes and lightning strikes and has a replaceable fuse for added protection against damaging voltage spikes.

Driverless technology is also far more forgiving in terms of exposure to high temperatures. The old chip-on-board drivers cope with temperatures up to 70 degrees Celsius, while the new driverless ones are fit for high operating temperatures up to 140 degrees, which is especially useful in factory environments.
