2013 SEES LED DOMINANCE OVER FLUORESCENT
The light quality and output from LED fi ttings now surpasses those of fl uorescent or halogen products and the reliability far exceeds traditional light sources. The main constraints in specifying LED of performance and price have now been removed.
The price of an integrated LED light fi tting is comparable to conventional technology when the total cost of ownership is included. LED fi ttings are more energy effi cient, have greater reliability and can be instantly controlled to further save energy.
LED changes the jargon Many building services professionals have a working knowledge of lighting performance; however the introduction of LEDs has changed those measures:
- Total Fixture Lumens is the measured light output from an LED fi tting.
- Circuit Wattage is the tested electrical usage of the complete fi tting.
- Lumens per Circuit Watt is therefore the true measure of energy effi ciency including driver losses.
- Light Output Ratio (LOR). Total fi xture lumens has replaced LOR for integrated LED light fi ttings.
- Colour Rendering Index (CRI) is a comparison to natural daylight. fi ttings should have a CRI above 80%.
LED
- Colour Temperature is the “appearance” of emitted light in degrees Kelvin. The lower the number the warmer the light; 3000 is considered warm and preferred in many UK households, where as above 4000 is cooler and generally specifi ed for commercial applications.
Selecting a fi tting? Ensure that the quoted lumens is actually delivered by the fi tting. For example, initial
lumens means the output from the LEDs and not that delivered from the fi tting with the diffuser or optic included. Ask for the total fi xture lumens. Check the total energy consumption of
the fi tting. Often the Wattage consumed by the LEDs is mentioned and the circuit Wattage including the electronic controls and drivers is conveniently ignored. What is the life of the fi tting? LEDs
are very reliable and can exceed 10 years continuous operation. The electronic control circuit is the weak link and dependent on the quality of the components.
Check the
expected life of the total fi tting and for added assurance get an extended warranty from a reputable supplier. Integrated LED fi tting or separate LED
lamp? LED lamps are generally less reliable than an integrated fi tting but can be replaced when they fail. It is JCC’s view that designing an LED light source to fi t a traditional lamp size is unreliable. We design integrated LED fi ttings from scratch to optimise light output and improve heat dissipation, removing the need for lamp replacement.
Fluorescent offi ce lighting is fi nished LED offi ce lighting is now more reliable, aesthetically appealing and easier to install than fl uorescent. JCC’s Skytile is a stylish 600 x 600 LED ceiling panel and at 2,700 lumens is equivalent to a 4 x 18W fl uorescent. At 79 lumens per circuit Watt it is double the energy effi ciency. The standard colour temperature of 4700K provides near perfect daylight. The ambient light and shallow cut off angles of Skytile also lend themselves to CIBSE LG7 compliance.

2D fi ttings are unsightly For years bulkhead lights have contained unsightly fl uorescent 2D lamps that can be seen through the diffuser. JCC has launched a range of LED bulkheads that use patented RadiaLED technology with the LED light evenly distributed. The need for a continuous program of re-lamping is eliminated along with the associated environmental issues of lamp disposal.
Integrated LED downlights look great Halogen and CFL lamps are unsightly and unreliable. Integrated LED downlights avoid lamp replacement and enhance an interior design.
For domestic downlights,
JCC
Fireguard is the market leader with FGLED7, using a startling 8 circuit Watts versus a 50W halogen equivalent. For commercial applications the 2,200 lumens Coral LED is a direct replacement for the old fashioned 2 x 26 watt CFL downlighter, 50% more effi cient and requiring no lamp replacement.
Change is always scary Sticking your head in the sand doesn’t help. LED lighting is now viable and widely specifi ed; the only questions are which product and which supplier? JCC have developed innovative LED products through extensive design and testing. We work closely with LED chip manufacturers to ensure our products use the latest technology and we provide a 5 year extended warranty.
