performance and reliability. The fixtures are also designed for easy access to the electronic driver to simplify maintenance.
GranVille II LED luminaires include cast aluminium housing available in multiple styles, including two utility series and four standard housings. The fixtures are offered with traditional GranVille trim options and mount to industry standard pole tenons and existing locations.
“New GranVille II LED luminaires provide present customers the cost effective option of retaining their pole, housing, glass globe, accessories and trim and simply replacing the light source and internal electronic components,” Prichard said. “The luminaires are suited to a range of environments, from parks and city streets to campuses, walkways and parking lots.”
GranVille II LED luminaires are OEM certified for retrofit of existing models. The new product family is pending regulatory listing and will be suitable for up to 400 C ambient temperature, depending on the selected wattage and options.
Headquartered in Granville, Ohio, Holophane provides energy efficient lighting systems for a range of commercial, industrial and outdoor applications.

With significant performance enhancements, LUXEON H enables the broadest range of retrofit bulbs and space constrained applications while providing the light output, efficacy, and quality of light required to meet ENERGY STAR specifications.
With a CCT of 2700K and 3000K with minimum 80 CRI, the LUXEON H has Freedom From Binning and a single 3-step MacAdam Ellipse colour space. With no flux bins and no Vf bins, the colour over angle is specified at a low 0.02 du’v. The device is hot tested and has a typical efficacy of 90 lm/W at 40 mA, 100V at Tj of 85°C.
The 100V / 200V package is rated for 4W – 8W. The typical flux is 320 – 660 lumens at 20 – 90 mA and 100V or 200V.
“LUXEON H is a major advancement that delivers unsurpassed quality of light in a package that’s easy to implement,” says Rahul Bammi, VP Marketing at Philips Lumileds. For the first time there is a practical solution for GU10 and other small form factor bulbs. Compared to other high-voltage or AC LEDs, LUXEON H delivers more light, better light, and better efficacy in a more cost effective package with proven LUXEON reliability.”
Compact and dimmable drivers are already available and LUXEON H is being designed into bulbs as a single LED solution which offers significant advantages over the multi-source designs previously required. The ease of solderless assembly reduces fixture manufacturing costs. Complementary components including drivers, optics, and clamps will be available through Future Lighting Solutions. The high volume release of LUXEON H will be in March.
