LED (Light-Emitting Diodes) technology represents the evolution of solid-state lighting, in which the generation of light is obtained by semiconductors instead of using a filament or a gas. LED Lighting Hire Sydney is more energy efficient, has a longer life and is more sustainable.
It also enables innovative and creative usage solutions that integrate light into our homes, cars, stores and cities. The LEDs are destined, over time, to replace traditional incandescent lamps and fluorescent lamps.
Thanks to the high illumination characteristic of the lamps and LED bulbs for Lighting Hire Sydney, it is possible to replace with them also the fluorescent lamps (compact or neon) with equivalent to LEDs that consume much less energy, that is power (in watts) decidedly lower, achieving a significant economic savings.
For example, it is possible to replace a normal 40 W neon lamp (of the T8 type with a diameter of 26 mm and a length of 120 cm) with a LED tube (consisting of almost 300 small LEDs) that consumes no more than 17 W.
In this case, assuming an electricity cost of 0.15 $/kWh and an average use of 6 hours a day, the annual consumption with the two different lamps would be 87.6 kWh and 37.2 kWh. Therefore, the annual savings in using the LED lamp instead of the neon fluorescent lamp would be 50.4 kWh, and therefore $ 7.5.
The LEDs maintain 70% of the initial light output even after 50,000 hours, according to EN50107 standards. This does not mean that we must necessarily replace them after this period, if this reduction does not create excessive discomfort they can be safely used until the complete loss of brightness, estimated at 100,000 hours.
Comparing the duration of the LEDs with respect to traditional lamps and assuming an average operation of 6 hours per day, we note that the average life of a filament light bulb is around 1000/1500 hours (250 days). The average life of a discharge lamp is approximately 4,000 hours (666 days). The average life of a fluorescent lamp is 6,000 hours (1,000 days). The average life of a LED lamp is 50,000 hours (8,333 days).
The luminous efficiency of a light source is the ratio between the luminous flux and the input power. The size is expressed in lumens/watts. The luminous flux is defined based on the subjective perception of the average human eye and corresponds to a particular curve within the visible light spectrum.
