Here are a few little facts you may or may not know about LED lighting
- 85% saving in electricity consumption compared to halogen bulbs and bulbs
- 50% savings compared to fluorescent and compact fluorescent lamps
- Up to 50,000 hours life where, for example. Halogen only lasts 1000-3000 hours
- No toxic mercury vapors in fluorescent and compact fluorescent lamps
- Amortisation of typically only 9-12 months
Benefits of LEDs
The long useful life of LEDs means reduced labor and maintenance costs. While the cost of a single fluorescent tube is relatively minimal, it may well cost several hundred dollars to bring in a bucket truck and change a burned-out tube in a box sign. Such replacements typically need to be made every few years, whereas LED illumination running 10 hours per day can last more than 13 years.
In fact, given many retailers and other clients rebrand their signs every seven to 10 years, LEDs can effectively last for the entire life of a sign without ever needing to be touched. They often carry a five-year limited warranty, require fewer system repairs and can eliminate the risk of damaging the sign during maintenance.
These savings can be realized in all box sign applications, but they make a particularly big difference for pylon sign installations where a bucket truck is needed to perform any servicing, adding to maintenance costs.
In addition to these cost savings are significant energy savings. LEDs can use 75 percent less power compared to standard T12HO fluorescent lamp ballasts. They only require 12 to 24V to the modules, which means more flexibility in both new construction and retrofits, as the number of circuit breakers is reduced and the wiring does not have to run through special wireways like its high-voltage counterparts do.
Accordingly, many utilities offer rebates for LED-based signage. In British Columbia, for example, BC Hydro has been offering rebates for four years. Signmakers should check with their local utilities to see if such rebates are offered and, if so, which documentation is needed to qualify for them. LED system vendors can usually provide the appropriate paperwork with ease.
The environmental benefits of LEDs extend beyond energy savings, as they also contain no lead, mercury or glass, making them compliant with such regulations as the European Union’s (EU’s) Restriction of Hazardous Substances Directive (RoHS) and allowing for easier disposal.
The technology also overcomes the cold-weather problems that have always plagued fluorescent lighting. With an operating range of -40 to 60 degrees C (-40 to 140 degrees F), LEDs can maintain consistent light output for a uniform appearance across a wide range of temperatures.
Even with these general benefits, however, not all LED systems are the same. When comparing them, there are a number of important factors to consider.
The overall reliability of an LED-based system is critically important in ensuring maintenance does not become an issue and the lumen output is kept consistent. Thermal management, for example, helps take heat away from an LED. Protection is also needed against humidity, corrosion and other environmental factors over time.
