One of the biggest differences between LED lighting and fluorescent or halogen light bulbs is their lifespan. LED’s have a lifespan of 50,000+ hours which equates to approximately 10 – 13 years of average use. Compare this to the lifespan of the traditional bulb that can last up to 8000 hours. These traditional bulbs also suffer what is termed a ‘catastrophic’ failure which essentially means they work until they don’t and when the die they pop! LED’s on the other hand very slowly lose their light output so even at 50,000 hours there will still be another 50,000 hours of light but just at a lower level. LED life spans are usually referenced as the L70% life. As the human eye can only detect light loss above 30%, LED’s are rated to this level. There is still plenty of light left after 50,000 hours but at a diminishing level.
LED’s can save you up to 85% of your power usage in comparison to your traditional lighting system.
Stop having to change bulbs
With LED lighting there is no need to constantly change bulbs. With a lifespan of up to 8000 hours fluorescent and halogen bulbs need to be changed regularly.
No hazardous chemicals
Fluorescent bulbs contain a variety of greenhouse gasses and mercury. This means they require specialized disposal processes. If a fluorescent bulb is broken, harmful gasses escape into the atmosphere. The mercury can leech into the skin and in some cases be fatal.
High safety standards
Unlike LED’s, fluorescent or halogen lighting use approximately 80% of their energy as heat. LED lights remain cool to the touch minimising the risk of burning or fire hazards. LED’s contain no glass components so are not vulnerable to vibration or breakage.
The importance of how we use lighting to help us minimise our impact of the environment is growing. 25% of all energy generated on the planet goes into lighting our world at a time when global energy resources are in decline. We must develop better, cheaper, more efficient ways of lighting our world. LED lighting technology provides many solutions to this global challenge.
The Ultimate Lighting Specification Guide
Insulation Rating: The Insulation contact rating determines whether the recessed downlight can be in contact with the insulation of your space. Modern lights that are rated IC have insulation that keep in the generated heat.
IC rating- Recessed fixtures with this rating have insulation adjoining or covering it. Most LED’s, and some florescent downlights have this rating.
ICF rating (Insulation Contact Fire Resistant)- Recessed fixtures with this rating have insulation adjoining or covering it. These LED downlight are sealed, fire-resistant and also water proof. These are best for use in areas like bathrooms and kitchens.
Brightness- The brightness of your LED downlight is measured in lumen. There may be some confusion between wattage and lumens. Although they are related in some ways- they don’t measure the same thing.
Lumens: This is the total measure of light emanating from your light source. The higher the lumens, the brighter the light.
Wattage- This lets you how much energy is used up to produce a fixed amount of lumens.
Cut-out- The diameter of the ceiling hole where a downlight fits.
Beam-Angle- The beam angle of a light source measures the spread of light from the light source. For a general, softer light, use a larger beam angle (90°-120°). A more narrow beam angle will provide a more accented highlight (see image below for details)
CRI- The CRI (color rendering index) is a measure of how accurately a light source illuminates objects' true colors. Our LED products have a CRI greater than 80- a CRI that can approximate halogen or natural daylight.
IP- The Ingress Protection rating is an international method used to describe the protection of a fitting to stop the penetration of solid objects or water entering the light fitting. Our product range come with an IP rating of 44- the recommended rating of a light installation to make sure water doesn’t enter the electrical.
Power Factor- is defined as the ratio of real power consumed by a load (expressed in Watts) to apparent power (expressed in VA), which produces a figure from zero to unity that indicates the degree of distortion and phase shift in the current waveform. A power factor close to 1 represents an ideal power.
Colour Temperature- The temperature refers to the colour characteristic of the light which can affect the atmosphere of a room. It ranges from a cool (bluish) light to a warm (yellow) tone. This attribute is measured in Kelvins:
<4000K: Warm White
>4000K: Cool White
Dimmable- The dimming factor that your LED downlight can attain. Dimmable lights are compatible with your dimming switches and can changed to match the mood of your room.
Housing Colours- The frame that surrounds a downlight is referred to as housing. You can select a colour of downlight housing to match with the decor of your space.
