Designed to provide high light quality, optical distribution and energy efficiency to heights of 2.5 to 25m for both internal and external applications, the LodeStar LED product range has been released by MHA Lighting. These LEDs are enabled by the company’s End Lit Rod (ELR) technology. According to MHA Lighting, this technology allows the company to install the lowest-powered fixtures on the market by combining high performance and light distribution.

To transmit and direct light into the workspace, the ELR technology utilises Total Internal Reflection. CoB LED modules are located at each end of acrylic tubes, hiding the LEDs from view. This reduces glare and creates an even light distribution, similar to that of a T8 array.

The LodeStar LEDs are claimed to be the most efficient and highest quality LEDs on the market, combining efficacies of up to 130lm/W (nett of all losses) with high light-beam distribution.

The ELR technology has already been recognised in MHA’s BrightStar 209 product. Lux Magazine’s technical editor, Alan Tulla, awarded the product five stars in his recent High Bay Review.

Tulla, who is also a Fellow and past President of the Society of Light and Lighting, commented: “Total Internal Reflection is an extremely efficient method of transmitting light and a highly reflective matt extractor materials means that very little light from the LED chip is wasted. The real benefit comes from the fact that the heat from the LED chip is spread over a wide area whilst the optical space remains cool.”

Tom Harrison, Managing Director, MHA Lighting, said: “We have been working hard for two years to develop this technology, patent it and create a market ready product range. To be able to officially launch it is a huge milestone for us all here at MHA and something we are incredibly proud of.

“What the MHA Team has created is more than an incremental improvement on existing technology, it is a fundamental step change in LED technology and its capabilities.

“We are in possession of something extremely powerful and highly innovative that is truly going to shape the future of the LED lighting industry,”added Harrison.

Dr Gareth John, Technical Director, Photometric and Optical Testing, said: “MHA has demonstrated an approach to LED lighting that is both innovative and interesting and is sure to pay dividends. This technology creates a pleasant, even light distribution, not unlike a T8 array but with the obvious advantages of LEDs.”
