Answer key prospect / customer questions in question and answer format.

What is an LED lamp?

An LED lamp uses one or multiple Light Emitting Diodes as the source of light. Each individual LED consists of a semiconductor diode that emits light when a voltage is applied to it. The first LED was created in 1927 but it wasn’t until 1962 that LED’s first appeared commercially as an electronic component. LED technology has now developed to the point where it is viable for general lighting applications.

Do I have to replace LED diodes?

An LED diode does not “burn out” like a conventional lamp, so individual diodes do not need to be replaced. The light output levels of LED’s will reduce gradually over a long period of time. For general lighting applications, the lifespan of an LED lamp is deemed to be when the lamp has lost 30% of its initial light output. In the rare instance where one LED fails, it will not result in the failure of the lamp.

Do LED lights have any other benefits?

Yes. LED lamps do no emit UV radiation which means that organic materials such as manuscripts, artwork and artifacts are not harmed. This benefit is particularly useful for museums and galleries where existing halogen lamps can cause UV degradation of displayed materials. Another benefit of LED’s having no UV emissions is that insects are not attracted to LED lights. LED lamps are therefore ideal for use in the food industry and as well as buildings which run external lighting for illumination.

What are the advantages of LED lights?

LED lights bring several advantages such as energy efficiency, durability, long lifespan, no UV emissions, no flicker and dramatically reduced maintenance requirements. This translates into energy savings, maintenance savings and an overall reduction in cost of ownership over the product's lifetime.

Where are LED lamps used?

LED lamps are now widely used in a variety of lighting applications such as car parks, airports, hotels, pubs, clubs, commercial offices, manufacturing industry, hospitals, aged car facilities, mining industry, traffic lights, automotive industry, boats, lifts, exit signs and many other areas.

How long is 50,000 hours?

There are 8,760 hours in a year, so here's what 50,000 hours works out to be, depending on lamp hours of operation.

Hours of Operation:

• 24 hours a day 5.7 years
• 18 hours per day 7.6 years
• 12 hours per day 11.4 years
• 8 hours per day 17.1 years

Why is the life span of an LED measured as lumen depreciation?

The life span of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the LED never really burns out, product life span is measured by lumen depreciation.

The Illuminating Engineering Society's (IES) current standard for calculating the life of an LED as the point at which the LED reaches 30 percent lumen depreciation.

Remember, a 100,000-hour rating is not equivalent to lamp life rating. LED life is rated where it has reached 30 percent lumen depreciation. At 100,000 hours an LED would still be operating, but at a decreased lumen output.

How do you evaluate LED lights?

Light output is only part of the LED story and can be misleading. To fully evaluate an LED light you need to review the overall system efficiency, the lamp fixture, the LED driver, optical control, thermal management of the LED’s and their lumen depreciation. Products with good optical efficiency and thermal management will be able to deliver more lumens, on average, than traditional lighting products.

Can LED lights be dimmed?

Yes, most of our range of LED lights can be dimmed using a standard dimmer unit.
