Symban and Accendo Partner to Deliver Energy Efficient Lighting Product Line

Digital HID™ Technology Surpasses LED in Performance and Price

Brampton, ON, August 14th, 2012: Symban Lighting, Canada’s leading independent manufacturer of commercial and industrial lighting fixtures has partnered with Accendo Electronics of Markham, Ontario to deliver a broad line of energy efficient lighting products. This line of fixtures is the first available in North America to incorporate digital high-intensity discharge (DHID™) technology which reduces energy use by up to 50% without compromising overall performance, and while extending lamp life. Accendo Electronics is the World’s leading manufacturer of electronic/digital ballasts for high-intensity discharge lamps including pulse-start metal halide (PSMH), ceramic metal halide (CHM) and high pressure sodium (HPS) lamps, those used extensively in exterior and interior commercial and industrial applications.

Traditionally, HID lamps are driven by magnetic ballasts which are inefficient, wasting large amounts of energy to released heat, and which degrade lamps, reducing their performance and shortening their useful life. Digital ballasts (or electronic ballasts) utilize a micro-processor to finely control the voltage and amperage levels and frequency delivered to lamps, resulting in less power consumed and extended lamp life. Heat losses are minimized saving additional energy. A typical 400 Watt exterior or high bay fixture can be reduced by up to 200 Watts by switching from magnetic to digital ballasts.

As LED (light emitting diode) technology is seeing increased use in low-light applications, LED systems have yet to prove viable for high-intensity lighting applications. The light efficacy of LED systems (i.e. efficiency measured in terms of light lumens delivered per Watt of energy consumed) and their overall brightness has not matched metal halide technology. This, while remaining 3-4 times more expensive. In addition, manufactures of high-intensity discharge lamps have invested heavily to extend lamp-life and improve colour performance, rekindling interest in metal halide, ceramic metal halide and high pressure sodium lamps. It is expected that these developments, along with new DHID™ technology, will drive a renaissance in high-intensity discharge lighting from these sources.

Symban Lighting is the first company to offer energy-saving DHID™ technology in a complete line of fixtures including wall-packs, flood lights, and canopy lights. These products will be made available through electrical and lighting distribution channels in Canada and the United States.

Benefits of Digital HID™ (DHID™) Lighting Retrofits

Retrofitting existing High Wattage HID lamp fixtures with more energy efficient and better performing DHIDTM ballasts benefits your project:

– DHIDTM Retrofit lighting solutions provide Industry the shortest Return On Investment
– Re-using, retrofitting existing magnetic ballast/lamp fixtures is environmentally responsible
Instant 40-50% energy savings, beyond 60% energy savings with smart dimming
– DHIDTM ballast technology improves HID lamp lifetime by 50%
– 90-95% lumen maintenance, originally specified light levels always remain (no relamping)
– Eliminate the long term expenses  and waste of lamp maintenance with Long Life Lamp solutions
– 10+ years, maintenance free solution, 40,000+ hours life MH, 70,000+ hours life HPS solutions

How does it work?  Old magnetic ballast HID lamp systems lose their light output over time, eventually losing over half of their initial light output.  Although light output has decreased, the magnetic ballast system continues to  consume the same amount of energy.

Accendo recommends the replacement of higher Wattage magnetic ballasts with lower Wattage DHIDTM ballasts.  Below is a typical Industrial high bay light fixture retrofit example.  The traditional 400W magnetic HID lamp system is upgraded/retrofitted with a 250W DHIDTM ballast, re-using the same fixture, only a new DHIDTM ballast and new matching Wattage lamp is installed.

Replace high Wattage magnetic HID ballasts with lower Wattage DHIDTM ballasts for instant 40%+ energy savings.  Application Examples; downloadable PDF Application Sheets (click):

DHID™ (Digital HID™) Vs. LED; Myths and Facts

When considering your lighting application solution, it is prudent to educate yourself on the available lighting types on the market today.  Given the recent surge of promotion and the popularity of LED lighting, many consumers assume LED to be the solve-all for every lighting application.  Although LED technology meets and exceeds the standards for many applications, one should be careful when considering LED for applications where light projection or penetration is important; i.e. applications where the light source is mounted at long distances from the target, as in Street Lighting, High-bay Warehouse, Sports Arena, Airport and Greenhouse lighting for example.

Facts about LED’s
  • LED’s present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching.  However, they are relatively expensive and require more precise current and heat management than traditional light sources.
  • It should be noted that high-power (≥1W) LED’s are necessary for practical general lighting applications.  Typical operating currents for these devices begin at 350 mA.
  • One of the highest efficiency ratings of high-power white LED’s is claimed by Philips Lumileds Lighting Co., with a luminous efficacy of 115 lm/W (350 mA).  Please note that these efficiencies are for the LED chip only, held at low temperature in a lab.  In a lighting application, operating at higher temperature and with drive circuit losses, efficiencies are much lower.
  • Independent testing of commercial LED lamps designed to replace incandescent or CFL lamps showed that average efficacy was about 31 lm/W in 2008 and tested performance ranged from 4 lm/W to 62 lm/W) compared with 100-116 lm/W of DHIDTM lighting systems.
  • Solid state devices such as LED’s are subject to very limited wear and tear if operated at low currents and at low temperatures.  Many of the LED’s produced in the 1970s and 1980s are still in service today. Typical lifetimes quoted are 25,000 to 100,000 hours but heat and current settings can extend or shorten this time significantly.

As a leader and one source supplier of advanced lighting systems for commercial and industrial lighting applications, including DHIDTM and specific LED lighting products, Accendo Electronics has studied and field tested both LED and the next generation Digital Ballast powered HID (called Digital HIDTM or DHIDTM) technologies for applications requiring long light penetration and retained light quality over extended time periods.  In our research, we uncovered key myths and facts about LED’s you should consider when deciding on your project lighting.

Myth: LED Lighting Life Expectancy is 100,000 Hours Plus


Manufacturers claim mean time before failure (MTBF) ratings on LED’s to be 50,000 hours to 100,000 hours or more.  Although in cases LED’s do meet these extended MTBF specifications, this number must be directly correlated to the LED application itself.  Factors such as mounting distance, the lumens per Watt (lm/W) rating, and operating temperature all contribute to the reduction of the LED’s MTBF.  Realistically, LED’s used for street lighting, or high-bay warehouse applications for example, may be considered to be failed at 30,000 hours or sooner due to the significant light diminishment incurred in the time stages of the LED’s operation.

The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency.  Sudden failures, although rare, can occur as well.  Early red LED’s were notable for their short lifetime.  With the development of high power LED’s, the devices are subjected to higher junction temperatures and higher current densities than traditional devices.  This causes stress on the material and may cause early light output degradation.  To quantitatively classify lifetime in a standardized manner it has been suggested to use the terms L75 and L50 which is the time it will take a given LED to reach 75% and 50% light output respectively.  L50 is equivalent to the half-life of the LED.


  • The LED light quality diminishes or dims over the operating lifetime of the LED bulb.  This degradation in light should be considered when reviewing the MTBF of LED’s since the light emitted at the LED’s life start is not equal to the light emitted at the bulbs half-life or life-end.  If the LED bulb cannot produce the light output originally specified, it is a form of failure.
  • Over time, heat created by LED’s also has an adverse effect on the systems light quality and MTBF. Depending on the class of the LED bulb used, factors such as powder coating (filter) degradation and the material used to manufacture the LED lens, further add to the truism that LED’s do not necessarily meet their manufacturer’s specified MTBF ratings and lighting quality claims.
  • DHIDTM equals or outperforms the longevity of LED in most industrial and commercial applications at lower costs.  The integrated microprocessor of the DHIDTM doubles the life expectancy of the HID lamp by maintaining full level of illumination up to 28,000 – 30,000 hours.
  • Studies have proven that DHIDTM used as a direct replacement and mounted at the same distance as the original HID lighting, outperforms LED in many quantifiable measurements of energy efficiency and light penetration.  DHIDTM offers a market leading lumens per Watt rating of 114 lm/W – 118 lm/W (which is 25% – 30% above LED’s lm/W rating) and therefore delivers higher energy efficiency, greater light penetration, and quality light up until its 30,000 hours MTBF; and all for a fraction of the cost of LED.

Myth: LED’s Project/Penetrate Light at Long Distances


Our studies proved that LED’s are not well suited for projecting light efficiently at distances exceeding 15ft (4.5m approx.).


  • At a typical street light height mounting distance of approximately 32.8ft (10m), the foot-candle (fc) measurements of the light emitted from both LED and DHIDTM were recorded at the ground:

-100W LED street light produced 0.75 foot-candles
-70W DHIDTM with a 70W Ceramic Metal Halide (CMH)
lamp produced 1.75 foot-candles

  • For street lighting applications the high lumens per Watt rating of DHIDTM provides the best value delivering higher energy efficiency, greater light penetration, and quality of light over time.

Where to Use LED Fixtures

  • Industrial and commercial applications where useful light penetration would not exceed 7 – 8 meters such as commercial room lighting, exit signs, target illumination in retail stores and others.
  • Flash lights, and other utility lighting.
  • Instrument panel lights and other back lighting applications.
  • Industrial and architectural back lighting, and other decorative applications.


Why DHIDTM (Digital HIDTM) is Preferred for Street Lighting and High-bay Lighting Projects

When selecting a lighting system, significant consideration should be given to the performance, cost, and life expectancy of both solutions.  Given the poorer lumens per Watt rating, high initial expense and realistic wear data of LED’s, we determined the DHIDTM solution to be the better value.

  • Progressively thinking end-users agree that DHIDTM 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 CMH or HPS lamps, the end-user can expect brighter 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 DHIDTM system CMH bulb fails, only the bulb itself needs to be replaced making it a most cost-effective alternative to expensive LED replacements.
  • Maintenance and control of a DHIDTM lighting systems is further simplified by Accendo’s Light Control Software which provides real-time tracking and performance data of each DHIDTM light via radio frequency (RF) communication.


Accendo Embraces the Use of LED’s for the Following Applications:

  • Wall packs and canopy light fixtures (currently under development).
  • Panel lights for architectural and special purpose lighting applications (currently under development).
  • Exit signs.


Over-all, DHID™ provides the Municipality/City clientele the Lowest Cost (<5 year payback), Most Proven (50,000+hrs. life, 90%+ lumen maintenance), Most Environmentally Responsible (re-use/retrofit fixture) Solution.

To replace existing H.I.D. lamp fixtures with LED ‘one-for-one’ requires an IES Specification Redesign: due to LED technology’s lower lumens per Watt (light output versus energy consumed), and lower penetrating light over distance. Technically, higher Wattage, higher cost LED fixtures are needed; OR pole spacing needs to be closer (more posts added), and mounting height needs to be lower to match the performance of DHID™ lamp technology.
