Cities, Towns, and Municipalities can be more competitive and environmentally effective today by significantly reducing the costs and electricity consumption associated with the operation of Street Lighting. By replacing antiquated Street Lighting systems with high performance energy efficient Digital High-Intensity Discharge (DHID or Digital HID) Street Lighting, 50%+ less electricity is consumed and demanded from the power utilities. When considering the upgrade of an existing HID Street Lighting system or lighting for new Street Lighting or Parking Lot applications, DHID technology delivers the best return on investment; offering a low initial buying cost, excellent energy efficiency, high system performance, lasting and penetrating light quality, and really low maintenance/consumable cost benefits. Typical Return on Investment time for the retrofit/replacement of a Street Lighting system with a GloGreen DHID 70W or GloGreen DHID 150W Digital Ballast is 1-2 Years.

Any existing core and coil (magnetic) ballast HID Street Lighting 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 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 Street Lighting or Parking Lot Lighting installation; it is the most cost-effective alternative to LED, and induction based technologies for new and retrofit Green lighting projects. Digital Ballasts offer unparalleled electrical efficiency and performance compared to conventional magnetic ballasts and outperforms LED 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, end-users can cost-effectively upgrade their conventional higher Wattage magnetic ballast HID Street Lighting or Parking Lot 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 Digital ballasts or DHID powered Street Lighting fixtures reduce lighting electricity costs by 50%+. For example, a conventional 250W Metal Halide magnetic ballast powered Street Light can be retrofitted with the DHID 100W Digital Ballast offering an immediate and significant 187.5Watts/hr per fixture (65%) savings in electricity with brighter, longer lasting light. Add the ability to dim the Digital Ballasts, and even greater energy savings can be realized. Add Light Management Software (LMS1A) to control the lighting network wirelessly; dimming lights on demand or on set schedules, electricity operating expenses are reduced by 75%+.

Application Examples:

Street Lighting Project – Pittsburgh, PA, USA.

Replaced 150W and 250W HPS utilizing core and coil (magnetic) ballasts with dimmable DHID 100W digital ballasts in existing cobra head fixtures.
A simple plug-and-play ballast retrofit or a simple replacement of the entire cobra head lamp fixture based on the DHID Digital Ballast.
DHID system favoured over competitors LED based design; DHID offered better performance and price.
Reduced inventory stock/costs; one DHID ballast powers inexpensive MH, CMH and HPS bulbs.
Excellent ROI; low maintenance/consumable costs (only inexpensive bulb need be replaced every 30,000hrs+).
Total direct savings: 72.5Watts/hr per fixture (42% savings) for magnetic 150W application and 187.5Watts/hr per fixture (65% savings) for 250W application; calculations including magnetic ballast energy losses (approx. 15%).

Renewable Energy Lighting Applications:

Retrofit existing HID based Street Lighting posts with Solar or Wind or Solar/Wind combined renewable energy sources for independent operation from the utilities power grid; or only partial draw from the utilities with the option to feed excess energy harvested back to the electrical grid.
Given the 116lm/W performance of the DHID lighting system, end-users can expect shorter Solar/Wind system battery charge times and extended light on times.
Solar/Wind produced energy can be used to efficiently power any of the Digital Ballast powered HID lighting systems to meet a variety of indoor and outdoor lighting applications.

Why DHID (Digital HID) is Preferred for Street Lighting and Parking Lot Lighting Projects Over LED

When selecting a Street Lighting or Parking Lot Lighting system, significant consideration should be given to the performance, cost, and life expectancy of the solution. Given the poorer lumens per Watt rating, high initial price, high consumable expense and realistic wear data of LED’s, end-users determined the DHID solution to be the better value.

Progressively thinking end-users agree that DHID is the more robust lighting solution with value added benefits not offered by LED; initial cost of investment, longer range of light penetration, and low maintenance costs were noted.
With Metal Halide (MH), Ceramic Metal Halide (CMH), or High-Pressure Sodium (HPS) lamps, the end-user can expect brighter penetrating light at the ground, with 30,000 hours of life expectancy and less than 5% degradation in light quality/brightness over the lifetime of the bulb. When a DHID system HID bulb fails, only the inexpensive bulb itself needs to be replaced making it a most cost-effective alternative to expensive LED array replacement, maintenance and consumable inevitabilities.
Maintenance and control of a DHID lighting system is further simplified by Accendo Light Management Software (LMS1A) which provides real-time tracking and performance data of each DHID lighting fixture via radio frequency (RF/GPRS) communication.
