MarulaLED wins award in Next Generation Luminaires™ Solid-State Lighting Design Competition
The Next Generation Luminaires™ (NGL) Solid-State Lighting (SSL) Design Competition has announced MarulaLED as a Recognised Winner for their entry of a Retail Low Bay pendant luminaire. MarulaLED is the first South African lighting company to win this prestigious award.
The award, presented at Lightfair International (LFI) 2012 in Las Vegas, is sponsored by the US Department of Energy (DOE), the Illuminating Engineering Society, and the International Association of Lighting Designers. The winning products were showcased at the LFI award ceremony, and circulation of the NGL 2012 Showcase Catalog will provide further promotion of the winning products.
“The Next Generation Luminaires™ (NGL) Solid-State Lighting (SSL) Design Competition seeks to encourage technical innovation and recognize and promote excellence in the design of energy-efficient LED luminaires for commercial, industrial and institutional applications. The idea behind NGL is to make it easier for lighting designers and specifiers to find LED lighting products that are worthy of specification. This means recognized products have to measure up on many fronts. NGL entries are judged on lighting quality (including color, illuminance, light distribution, and glare), appearance, serviceability, efficacy, value, dimming, and rated lifetime – and the bar was raised even higher this year, to reflect improvements in the technology.” (from NGL winners press release, 10th May).
“This is not just a one-dimensional contest,” said DOE Solid-State Lighting Program Manager Jim Brodrick.“Beauty alone won’t cut it – the winners have to really ‘walk the walk.’”
MarulaLED is proud to be in a list of NGL Recognised Winners that includes all of the giants in the LED lighting industry, with Osram, Philips, General Electric and Cree Lighting all receiving awards.
The LB86 Low Bay was developed jointly with MarulaLED's OEM partner Megalite, who market and sell a number of LED luminaires that utilize MarulaLED's CoolTube-based light engines. The low bay utilizes theLE86 light engine and provides 9200 lumens of light output in a natural white colour with a relatively high CRI (other colours are also available), with wired or wireless control of dimming and beam angle.
“MarulaLED's low bay stood out from all other commercial luminaire winners in terms of light output. This was while providing an aesthetically pleasing, low weight luminaire that would be suitable for a retail environment” said Colin Andrew from MarulaLED. “This is due to the novel cooling technology utilized in the luminaire's light engine. CoolTube™ eliminates the need for the aluminium heatsinks that, when scaled up to support higher light outputs, become heavy, bulky and unsightly, often creating luminaires that are far from attractive and are not fit-for-purpose” This sentiment was reflected in the judges comments.

The judges did question the fact that a fan was used for cooling. “There is often a negative sentiment to fan-based cooling in the lighting industry” said MarulaLED's Ruud de Vaal. “However, modern fans now provide life spans that can exceed LED life spans and that have excellent dust resilience. Also, constant airflow close to the LEDs and lenses prevents dust build up that would have otherwise caused reduction in light output or required maintenance.”
