Choosing the right circuit protection for LEDs

Approximately 25% of global energy consumption goes to lighting applications, so making lighting more efficient could have a dramatic impact on overall energy usage or make more power available for other uses. Legislation designed to discourage the use of incandescent lamps has been a significant factor in the growth in demand for LED lighting equipment. At the same time, both consumers and industrial users are increasingly interested in energy efficient lighting options, further stimulating the demand for LED lighting.

Technical innovations that impact LED efficiency (more lumens per watt), secondary optics (better lenses/reflectors), and thermal dissipation are increasingly allowing LED lighting to replace legacy light sources like mercury vapor, metal halide, and sodium vapor lights in outdoor applications.

However, outdoor LED lighting can be very expensive to install; payback must be determined based on lower wattage demands, lower maintenance costs, and a longer operating life.

To prevent outdoor LED lighting from experiencing failures within an investment payback period of about five years, high durability and reliability are essential. Transient surge events in AC power lines represent a serious threat to outdoor LED lighting fixtures.
