LED comparision chart

Light  Output                       Light Emitting Diodes (LED’s)  General Filament Light Bulbs Compact Fluorescents (CFL’s)
 Lumens  Watts  Watts  Watts
 450  4 – 5  8 – 12  40
 300 – 900  6 – 8  13 – 18  60
 1100 – 1300  9 – 13  18 – 22  75 – 100
 1600 – 1800 16 – 20  23 – 30  100
2600 – 2800 25 – 28 30 – 55  150

Watts are a measurement of power – and so of how much power a light bulb draws – rather than of how bright a bulb is.

Lumens are the unit used to measure light output, or brightness. So it’s the lumens figure you need to have in mind when buying a new bulb. As a general rule, the greater the wattage the greater the lumen output and the brighter the light, but only when comparing similar types of light bulb.

With energy prices rising… now is a great time to consider energy saving lamps.

For example a typical household room with 10 downlighters. When switching from Halogen to LED lamps you could save up to £124.20 per year.

So what could be your savings if you convert your whole household or office to LED lamps?
What does LED stand for?
LED – Light Emitting Diode

Where are LED lights being used?
Since LED lights are so energy-efficient, the most common applications are places where lights are switched on for an extended period of time. You can find LED lights in restaurants, offices, parking lots, streetlights, and homes.

Why is LED lighting better than fluorescent lighting and CFLs?
LEDs don’t contain hazardous materials, such as mercury. Since fluorescent tubes and CFLs contain mercury, they must be properly disposed of in order to prevent mercury from poisoning landfills.

Why LED lighting better than incandescent bulbs?
Most of the energy emitted from incandescent bulbs is converted to heat instead of light. That’s why you’ll burn yourself if you try to touch an incandescent bulb once it’s turned on.
LED lighting is about 85 percent more efficient than incandescent bulbs. Since LEDs consume significant less energy, they don’t emit as much heat.
LED lights are also designed to last about 50 times longer, which means less ladder-climbing maintenance and less waste.

What’s so great about LEDs?
LEDs can be used to build energy-efficient lighting products that save energy, help protect the environment, reduce maintenance costs and they can last much longer than traditional lighting.

Just how energy-efficient are LED lights?
LED lighting can save up to 85 percent of the electricity used by incandescent bulbs and up to 50 percent of electricity used by fluorescents

How long can LED lights last?
With the right design, LED lights can have a lifetime of 50,000 hours and more in continuous operation. Depending on how many hours-a-day they are operating, that can be from 6 to 7 years to as many as 20 to 30.

Unlike other lighting technologies LEDs do not completely fail—they grow dimmer. At the 50,000 hour mark, Cree’s LED lights are designed to provide at least 70 percent of their initial light output. Many different factors (such as fixture design and operating conditions like temperature and current) determine the actual lifetime of an LED.

Aren’t LED lights too expensive?
A main challenge with LED lighting is that it costs more upfront, but really, it’s no different than requiring insulation in homes and buildings. It can pay for itself over time with energy savings and lower maintenance costs. Keep this in mind when you initially invest in LED lights.

Besides, how do you define expensive? Is it purely the up-front cost of a light or do you factor in the cost of the energy to run that light and, if you’re a business or government, the cost to change the lightbulb? And if you’re building a new building, installing LED lighting is often just about the same cost as traditional technology—and you’ll start saving money, through reduced energy consumption, the minute you flip the switch.
