DHID Vs. LED; Myths and Facts:

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 DHID 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.

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


• False! 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.

Facts:


• 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.
• DHID equals or outperforms the longevity of LED in most industrial and commercial applications at lower costs. The integrated microprocessor of the DHID doubles the life expectancy of the HID lamp by maintaining full level of illumination up to 28,000 – 40,000 hours and beyond when smart dimming is utilized.
• Studies have proven that DHID 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. DHID offers a market leading lumens per Watt rating of 116lm/W+ (which is 25% – 30% above LED’s lm/W rating) and therefore delivers higher energy efficiency, greater light penetration, and quality light over the entire 40,000+ hours MTBF; and all for a fraction of the cost of LED.

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


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

Facts:


• 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 DHID were recorded at the ground:
  • 100W LED street light produced 0.75 foot-candles
  • 70W DHID with a 70W Ceramic Metal Halide (CMH) lamp produced 1.75 foot-candles
• For street lighting applications the high lumens per Watt rating of DHID 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 is DHID 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 all possible solutions. LED, fluorescent and induction lighting have poorer lumens per Watt ratings, higher initial buying prices and inherently suffer light quality and penetration degradation; whereas DHID’s high performance light output, low initial buying cost, and low maintenance/consumable costs over the long term offer your project a shorter and better return on lighting investment value.
• Progressively thinking end-users agree that DHID is the more robust lighting solution with value added benefits not offered by LED, fluorescent or induction; Multiple Bulb Capability, Smart Dimming, 116+lm/W, 97% efficiency, and 95% lumen maintenance ensure application flexibility and optimal energy and lighting performance over the long term.
• DHID is the environmentally responsible lighting solution, reuse your existing lighting fixture; reduce waste and reduce your over-all project costs.
• With MH, CMH or HPS 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 (95% lumen maintenance).
• When a DHID system HID bulb fails, only one inexpensive bulb needs to be replaced; making DHID lighting the most cost-effective and environmentally friendly alternative to the more expensive labour/maintenance, consumable cost and waste inevitabilities of alternative lighting technologies. With DHID, relamping is no longer required since originally specified light levels will always remain constant throughout the entire lifespan of the HID bulb.
