Cities, Towns, Municipalities and Power Utilities can be more competitive and environmentally effective today by dramatically reducing the costs and electricity consumption associated with the operation of all Street and Parking Lot Lighting, Building/Warehouse Lighting, and Public Park, Sports Field and Arena Lighting. By simply retrofitting or replacing antiquated magnetic High-Intensity Discharge (HID) lighting systems with high performance energy efficient Digital HID (DHID) lighting, the end user can yield an immediate 40% or 50% savings in energy while still maintaining equivalent light levels. Introducing dimming allows for 75% or more in additional energy savings. Money savings due to reduced electricity expenses allow the payback of the DHID lighting solution to be really short, and with minimal maintenance and consumable expenses incurred over the long term.

Given the ability to retrofit the GloGreen DHID ballast into the existing magnetic based fixture, old street light and parking lot fixtures can be reused, greatly reducing waste and project costs. The newly retrofit street light or parking lot fixture is rejuvenated and able to deliver equivalent or greater penetrating light output to the ground for a fraction of the electricity consumed. For example, Accendo Engineers recommend the direct replacement of an old 250W magnetic ballast system with the new GloGreen 150W Digital HID Ballast. This upgrade maintains equivalent light levels, but with 45% less energy consumed. For new street lighting, parking lot lighting, and antiquated fixture replacement applications, consider GloGreen DHID ballast powered turnkey street light fixtures; the most cost effective, highest performing lighting solution with the lowest maintenance consumable costs for the shortest realistic return on investment.

When considering the upgrade of an existing HID lighting system or lighting for new Green projects; DHID technology guarantees the best return on investment with a low initial buying cost, excellent energy efficiency, and high system performance which benefits with lasting and penetrating light quality (95% lumen maintenance). The typical return on investment time for the retrofit/replacement of a core and coil (magnetic) ballast powered street lighting or sports field lighting system with a new/retrofit GloGreen Series Digital HID retrofit ballast is only 1.5 years to an industry leading <6 months (for any magnetic 70W to 2000W HID retrofit applications).

First To Market With Multiple Bulb Capability DHID Ballasts


Accendo continues to evolve its Digital HID ballast technology to meet the specific needs of our Municipality and Power Utility clients. We lead the market with innovations geared towards economical and environmental responsibility. For example, the new GloGreen Series Digital HID ballasts are the only on the World market to offer Multiple Bulb Capability. Based on research conducted with the support of our clientele, it was determined High-Pressure Sodium (HPS) and Metal Halide (MH) HID bulbs are the most widely used, most proven and accepted for the variety of municipality client applications. Now one digital ballast can operate both MH and HPS bulbs with equal efficiency, significantly reducing environmental waste and costs associated with municipality inventory stores.

Brighter, Longer Lasting Light Guaranteed


HPS and MH bulbs powered with the GloGreen DHID ballast can now last 50,000 hours or more without suffering more than 5% degradation in light quality, light penetration, or efficiency performance for the entire extended mean time before failure rating or life of the HID bulb. Lighting based on LED, fluorescent and induction inherently suffers losses in light quality/penetration output over the lifetime of the systems operation; lights which no longer operate at their full brightness capacity and no longer meet the original specification of the application need more frequent replacement or relamping, leading to inevitable and expensive labour and consumable costs over time.

GloGreen Digital HID ballasts are built to withstand a variety of installation scenarios, all are fully silicon potted for operation in harsh or wet environments. The robust design is ideal for Industry’s most demanding applications including operation in extreme cold; GloGreen ballasts have proven to operate well even outside of their specified -25C to 70C temperature ratings. Our research determined that typically if the bulb specification states that ignition is possible below -25C, the DHID ballast will ignite it.

Environmental And Economical Benefits


Any existing core and coil (magnetic) ballast HID street lighting or parking lot application can benefit immediately just by retrofitting the old magnetic ballast with a new GloGreen 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 and bulb need be purchased, leaving only the old ballast and bulb to be recycled (we partner end-users with recommended magnetic ballast and HID bulb recycling companies).

DHID's value added features and performance also make it the smart solution for any new lighting installation; it is the most cost-effective alternative to LED, fluorescent and induction based products for new and retrofit 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 brightness/quality over time, and maintenance/consumable costs.

Maximize Your Energy And Money Savings


The GloGreen Series Digital HID lighting solution offers very cost-effective opportunities to maximize your energy and money savings:
  • 97% efficient DHID ballast replaces inefficient magnetic ballasts with a brighter solution which immediately consumes 40% to 50%+ less electricity.
  • Introduce dimming to maximize savings; parking lots, garages, warehouses, pathways, parks, sports fields; anywhere people or vehicles are not always present.
  • Introduce Pre-Programmed Dimming modes or Accendo Light Management Software (LMS1A) for complete control of the lighting network and 75%+ savings.

With an industry leading luminous efficacy of 116+ lumens/Watt, end-users can cost-effectively upgrade their conventional higher Wattage magnetic ballast HID lighting fixtures with a lower Wattage (half the Wattage) GloGreen digital ballast powered HID solution which offers brighter, longer lasting, penetrating light for a fraction of the electricity cost previously incurred with the magnetic ballast application. The new higher-performance, yet lower wattage DHID powered street lighting fixtures can directly reduce lighting electricity costs by 40% to 50%+. For example, a conventional 250W High-Pressure Sodium or Metal Halide magnetic ballast powered street or parking lot light can be retrofitted with the GloGreen 150W Digital Ballast offering an immediate and significant 40% to 50% savings in electricity with brighter, longer lasting light. Add the ability to dim the DHID ballasts, and even greater energy savings can be realized. Smart dimming capabilities are already included in all GloGreen Digital HID ballast models; dim via motion sensor or on-board pre-programmed schedule; or integrate Accendo Light Management Software (LMS1A) to control the lighting network wirelessly; ignite, dim or instantly resume to full power, and turn lights off, on demand or on set schedules to reduce electricity consumption by 75%+. LMS1A also allows you to view the lighting network operation in real-time and store historical data for accurate tracking of the systems operation and more efficient maintenance scheduling.

Why DHID is Preferred for Municipality Lighting Projects Over LED, Fluorescent and Induction


GloGreen Digital HID retrofit/upgrade ballasts and lighting fixtures provide City, Town, Municipality and Power Utility clientele a one source solution for all Street/Parking Lot Lighting, Building/Warehouse Lighting, and Park/Sports Field/Arena Lighting applications. When selecting an energy efficient lighting system, significant consideration should be given to the performance, cost, and life expectancy of the solution. Given the poorer lumens per Watt rating, higher initial price, and the realistic wear data and consumable expenses of LED, fluorescent and induction based systems; end-users determined DHID lighting to be the best value-added lighting solution which can solve several common applications with one product line.
  • Progressively thinking end-users agree that DHID is the more robust lighting solution with short and long term investment benefits not offered by LED, fluorescent or induction; DHID’s initial cost of investment, longer range of light penetration, low maintenance costs and application flexibility were favourably noted.
  • GloGreen DHID ballasts are robust; fully silicon potted/sealed to withstand outside wet, extreme cold and hot environments for the trouble free operation of HID bulbs.
  • Multiple Bulb Capability; with proven High-Pressure Sodium (HPS), Metal Halide (MH), and Ceramic Metal Halide (CMH) lamps, the end-user can expect brighter penetrating light at the ground, with 40,000 hours or more of life expectancy and less than 5% degradation in light quality/brightness over the lifetime of the bulb.
  • When a Digital HID system bulb reaches its life-end, only the inexpensive bulb itself needs to be replaced making it a more cost-effective alternative to lower light quality LED, fluorescent and induction based systems which require more frequent and hence more expensive light source replacements to match the long term light penetration and quality standards set by DHID lighting.
  • Instant dimming for an instant 65%+ savings in energy consumption. Simply one-step dimming the DHID light system to 50% of its rated power via motion/heat sensor, switch or pre-programmed schedule can equate to significant money savings over time. On-board programmed/scheduled dimming reduces light output at pre-specified times of the day.
  • The control and maintenance of a DHID lighting system is further enhanced by Accendo Light Management Software (LMS1A). It provides real-time wireless management of your lighting network, including the tracking and performance data for each individual DHID lighting fixture via radio frequency (RF/GPRS) communication. LMS1A allows for a most dramatic 75%+ savings in electricity consumption and dimming is seamless, from 100% to 30% of the DHID ballast output power.
