Martineztown neighborhood first to get new LED lighting

ALBUQUERQUE, N.M. (KRQE) – The historic Martineztown neighborhood is the first to get new LED lighting from the city.

Over the past year, the city and lighting company Citelum have worked together to engineer a custom “lighting master plan” for Albuquerque.

It includes converting more than 20,000 lights to LED bulbs. The city says it makes the city safer while saving millions of dollars in electric costs.

“It’s just a night and day difference on seeing pedestrians, being able to see cyclists, seeing other vehicles. Our police department is extremely excited,” Mayor Richard J. Berry said.

The mayor says the project will also reduce the city’s carbon footprint.

LED vs CFL vs Incandescent

Both CFLs and LEDs use considerably less electricity than traditional bulbs. As you can see, buying longer-lasting, more efficient light bulbs can really pay off over time. Over a 23-year period, it will cost you over $200 (and many trips to the hardware store) to keep one 60-watt lamp lit with incandescent bulbs.

How efficient are LED light bulbs?

Compare LEDs to compact fluorescent lights (CFLs) with 55-70 lumens per watt, and traditional incandescent bulbs with 13-18 lumens per watt, and the LED advantage is bright as day. LED manufacturers are not only increasing efficiency, they're expanding options.

How much money do you save with LED lights?
The LED bulb uses only 25 cents' worth. So the LED saves $1.23 per year. Since it costs $20, it will take 16 years to recoup the cost in electricity savings. At five hours a day, the incandescent uses $15.42 in electricity annually.

What is the equivalent wattage for LED bulbs?
(The point, after all, is that they draw less energy.) For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts. But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.
