A recent study indicates that Africa could save $10 billion in energy costs annually by converting to LED lighting. During a Philips road show from Cairo to Cape Town, solar-powered LED street-light installations are helping to address lighting needs when electricity is unreliable.
Africa could save up to N1.63 trillion ($10 billion) in annual energy costs if it switched from incandescent to LED lighting. The change would also reduce carbon emissions by more than 50 million tonnes, which is the equivalent output of 35 power stations. These were the key findings of a recent research study conducted by Royal Philips. These figures reflect only on-grid lighting where electricity currently exists.
Nick Kelso, senior communications manager, Philips Lighting Africa, added that LED solutions, when combined with the latest innovations in battery and solar developments, can provide practical and sustainable light for some 600 million Africans who currently live without electricity according to the International Finance Corporation, a division of the World Bank.
“With this in mind, we see the need for new LED solutions in Africa, and the best place to begin is Nigeria, where we believe, there is a massive market waiting to be tapped,” said Kelso.
In fact, as part of Philips’ African road show , it has begun installing solar-powered LED street lamps in Ghana and Marrakech using the Solar Gen2 lamps as well as an entry-level range of cost-effective LED street lights with lumen packages of 1500 to 6000 lm. Both product lines allow up to 30% higher transfer of energy from the solar panel to the batteries than is offered by traditional change controllers according to Philips.
Eric Heutinck, general manager, Philips Lighting’s Maghreb and West African regions summarized ‘‘Quality LEDs offer part solutions to some of the key issues we face today, including energy crisis, climate change, resource scarcity, safety in our cities and an enhanced sense of health and wellbeing.’’
Philips predicts that in 2020 approximately 75% of the global lighting market will be LED based. The company estimates that full switch to LED lighting would provide up to 80% energy savings in many applications or an average of 40% for all lighting applications.

Cree has extended the efficiency record for a white LED tested at room temperature and 350 mA current.
LED manufacturer Cree, Inc. has claimed a new R&D record for power-LED efficiency of 231 lm/W. The value was measured for a single-die component at a correlated color temperature of 4500 K.
Standard room-temperature testing at 350 mA – i.e. pulsed testing rather than steady-state or “hot” testing – was used to achieve the results.
Cree described the result as “a significant advance beyond [our] previous industry record” of 208 lm/W efficacy for an R&D LED, which was reported in February 2010. The company also said the result “further demonstrates how Cree’s relentless innovation continues to push the boundaries of what is possible with LED lighting.”
“It wasn’t long ago when 200 lumens per watt was considered the theoretical maximum efficiency for a lighting-class LED. We broke that barrier in 2010, and have now achieved 231 lumens per watt,” said John Edmond, Cree co-founder and director of advanced optoelectronics.
“The innovation from our labs is the foundation for our industry-leading XLamp LED family and an invention that continues our leadership of the LED lighting revolution.”
Cree says that the results came from an R&D component that features advanced aspects of the same technology used in the company’s XLamp white LEDs. The same level of performance is not yet available in Cree’s production LEDs.
Cree says it believes higher-performance LEDs can enable new LED-based applications and drive down the solution cost of current LED-based designs.
