Digital High-Intensity Discharge (DHID) lighting technology is leading Industry’s energy efficient lighting evolution with a solution to lighting upgrades which is cost-effective, high-performing and the most responsible for the environment. Accendo Electronics Limited, a Canada and United States based lighting manufacturer, is a champion for the economy and the environment and is innovating with the World’s most robust lighting solutions for Industry. The new GloGreen DHID retrofit ballasts and lighting fixtures offer many value added benefits on the upgrade of any outdoor or indoor HID lighting application. The retrofit upgrade is a simple solution which reduces lighting expenses by fifty to seventy five percent or more, and produces very little waste since existing lighting fixtures can be re-used.

1. DHID (Digital HID) Lighting Reduces Industry Lighting Expenses by 50%+
Industry can be more competitive and environmentally effective today by significantly reducing the costs and
electricity consumption associated with the operation of lighting. By replacing antiquated lighting systems with
high performance energy efficient digital High-Intensity Discharge lighting (DHID or Digital HID), 50%+ less
electricity is consumed and demanded from the power utilities; cost-effectively reducing Industry's carbon
footprint. When considering the upgrade of an existing HID lighting system or lighting for new Green Building
projects, DHID technology delivers the most energy efficient lighting solutions for Street Lighting,
Factory/Warehouse High-Bay Lighting, Greenhouse Hydroponics, Sporting Arena, Airport and Renewable
Energy Applications.
Any existing core and coil (magnetic) ballast HID application can benefit immediately just by retrofitting the old
magnetic ballast with a new DHID ballast. From an environmental standpoint, by reusing the existing light fixture
and lens assembly, less waste is created and money is saved since only a new ballast need be purchased,
leaving only the old ballast to be recycled (we partner end-users with recommended magnetic ballast recycling
companies).
DHID's value-added features and performance make it the smart solution for any new installation; it is the most
cost-effective alternative to LED, Fluorescent and Induction based technologies for new and retrofit industrial
and commercial Green lighting projects. Digital Ballasts offer unparalleled electrical efficiency and performance
compared to conventional magnetic ballasts and outperforms LED, Fluorescent, and Induction lighting in initial
buying cost, energy efficiency, system performance, light quality, and maintenance/consumable costs.
With an industry leading luminous efficacy of 116 Lumens/Watt, conventional higher Wattage magnetic ballast
HID lighting fixtures are now easily upgraded/retrofitted or replaced with the new higher-performance, yet lower
wattage DHID Digital ballast or fixture. For example, a conventional 1000W Metal Halide magnetic ballast, can
be retrofitted with the DHID 575W Digital Ballast offering an immediate and significant 50% energy savings and
approximately 18% brighter light. Add the ability to dim the Digital Ballasts, and even greater energy savings can
be realized. Add Light Management Software to control the lighting network wirelessly; dimming lights on
demand or on set schedules, electricity operating expenses are reduced by 75%+.
