One of the key features of the LEDs is the directional nature of its light emission.

It is noted that directional lighting significantly reduces the energy needed to achieve the desired luminosity at the intended location. Fluorescent and Incandescent lamps, on the other hand, emit light in all directions and much of the light produced by the lamp is lost within the fixture or reabsorbed by the lamp. Hence, it is not uncommon that up to 40 to 50% of the total light output of the fluorescent and incandescent lamps are wasted.

Another notable feature of the LEDs is that they do not easily “burn out" like CFL and incandescent, which often create uneven or total loss of illumination; the LEDs gets progressively dimmer over time, known as lumen depreciation. The useful life of LED is typically based on the number of operating hours until it drops to 70 percent of its rated luminosity.

Good-quality LEDs in well-designed fixtures are expected to have a useful life of 30,000 to 50,000 hours or even longer. A typical incandescent lamp lasts about 1,000 hours while a comparable CFL lasts between 8,000 to 10,000 hours.

With their longer lifespan, the LEDs do not need to be replaced regularly and hence they can be suitably installed at locations such as warehouses, workshops and remote areas that are generally inaccessible, and the downtime and labor costs to replace the lights are extremely high.

Besides the service lifespan, the frequency of switching on/off is another factor to consider when choosing between LED and conventional lightings. The frequent switching on/off of the CFL and incandescent lights can get them burnt out easily and thus shorten their service lifespan.

 

In contrast, LEDs are made of solid-state devices and they are not susceptible to burn out from the frequent switching on/off. LED lights with motion sensors are therefore preferred at locations such as restrooms, wardrobes and passageways since the illumination are generally short but highly frequent based on the nature of the human activities at these places.

Leveraging on these key strengths of the LEDs, Hemera Opto-Electronics has lined up a range of high-quality indoor and outdoor LED lightings that serve as good alternatives to the CFL and incandescent lightings.
