Halogen versus LED (Introduction)

 

Would you like me to pay your home electric bill for 40 years? Recently, I was asked by a commercial entity to repair their lighting system which had been neglected for approximately 18 months. Upon evaluating the situation, the repairs were significant enough that it made sense to think about rolling those costs into converting the existing halogen system to an LED system. LED systems will save such a significant amount in power costs alone, that converting this existing halogen lighting system to a light emitting diode (LED) system will make a lot of sense. Additional savings can be realized in lamp and service fees. Although halogen systems are the most prevalent systems in place today, the fact is, it would take 20 halogen light bulbs, or 8 compact fluorescent lamps (CFL) to light a project for the same time span. Further, the reduction in energy demand offered by LEDs results in reduced carbon-based emissions. Since 25 percent of the United States’ annual electric bill comes from lighting, switching to LED lamps could save $34 billion in national electric costs.

Another factor worth considering is the amount of heat generated by LED fixtures is 90 percent less than the heat generated by halogen lamps, which offers a safety enhancement for pedestrian traffic, especially small children, making their way through the property. Most people already understand the value that lighting brings to a property with increased safety for pedestrian traffic, providing illumination to navigate around elevation changes and obstacles that may trip one up. Lighting also presents less opportunity for those who would seek to ambush innocent by passers; and the aesthetic value that lighting adds to your property is the best feature. 

Although replacing the project’s lighting fixtures is a fairly large expenditure, the benefits of this conversion will be a good value when evaluated over the life of the system. To better help us understand all the factors involved in evaluating an LED conversion I would like to take you through the system technologies to help explain the differences between the LED and halogen processes, and look at why the conversion will be a good investment for the project. We will then do a comparative analysis of the relative costs of an LED conversion covering various time frames to determine the most economical way to do achieve the desired result.
