Top Five Advantages of LED Lighting

  1. Efficiency – We’ve all heard about the energy efficiency of LED lights, but what’s the real story? Compared with fluorescent and metal halide, well designed LED lights will typically use between half and one quarter of the power to achieve the same light output. Compared to halogen or tungsten, the savings are even greater. Whilst it’s true that light emitting diodes are fantastically efficient light sources, the light fixtures need to be properly designed to maximise this efficiency without damaging the LED itself and degrading its light output over time.
  2. Lifetime – LED Fixtures last many times longer than their traditional counterparts, removing the cost, downtime and inconvenience of having to hire access equipment and purchase of new lamps. The long lifetime of LED products really comes into its own when considering difficult to access areas, such as the roofs of factories, warehouses and hangars, and for decorative architectural lighting on the sides of buildings. Pulsar is unique in having an installation of LED lights that have been operating for over 100,000 hours, meaning that our fixture lifetime claims are based on actual evidence, rather than predictions.
  3. Instant Switching/Controllability – Ever seen street lights, industrial lights or energy saving bulbs that seem to take forever to light up fully? A huge advantage of LEDs that’s not so immediately obvious is that the lights switch instantaneously. As well as being far more convenient, this means that it’s possible to take full advantage of technologies such as motion sensing and daylight harvesting, which can dramatically increase financial and carbon savings. Also, unlike other types of light source, frequently switching LEDs on and off does not affect the life of the fixture at all.
  4. Light Quality – Since LEDs are available in a plethora of colour temperatures, it’s possible to have LED lights that replicate the warm glow of tungsten, the natural clarity of daylight, or anything in between. Want something more colourful? LEDs are unique in using additive colour mixing- this means that you can have over 16 million colours from one light, without needing gels. This quality and versatility makes it simple to get the right light.The ability of LEDs to render colour has also dramatically improved in recent years; Pulsar offer LED luminaires with a CRI of 95 (almost as high as natural sunlight, which is considered to have perfect colour rendering with a CRI of 100)
  5. Directionality – An advantage of LED lights that isn’t brought up so often, LEDs only give out light in one direction, rather than the omnidirectional light output of most lamp types. This means that light isn’t lost into the back of the fixture, which further increases the performance of LED lights compared to traditional tech. It also makes a very fine degree of control possible over the spread of light, which means that well designed LED fixtures can direct light to exactly where it is needed.
