LED Lighting Top Priority for US Cities - a summary

A recent survey ‘How energy Technologies are Reshaping America’s cities' found that the mayors of American cities rank energy-efficient LED lights as the most promising technology to combat carbon emissions and reduce energy use over the next few years. 41% of cities ranked LED lighting as their top priority, next on 18% was solar energy and 17% with low-energy buildings.

In terms of particular uses of LEDs for street lighting was the most popular application at 81%, followed by city owned buildings on 65% and public parks and sports fields on 51%.

 

The popular choice of LED lighting technology is due to the obvious economic benefits in vastly reducing electricity and maintenance costs whilst increasing energy savings. From a visual perspective LED lights can much better resemble natural day light which creates more aesthetically pleasing experiences in spaces such as footpaths and parks.

 

As usual the major obstacles to achieving these targets were financial constraints with 67% stating local budget restraints, 49% the high up front cost and 33% stating limited or no available federal funding.

What to consider when buying LED lights - watts, lumens and kelvin.

In this brief post we will try to explain what lumens and kelvin mean when looking to buy LED lights. When you begin to think about replacing your traditional light bulbs with LED light bulbs then you need to go in with a different view than you would purchasing light bulbs such as incandescent.

- Don't look for watts, but look for lumens (lm). Watts aren't to do with brightness anyway but rather a measurement of energy used. LEDs are measured in lumens and that gives you an indication of the level of brightness. The higher the lumen the brighter the bulb.

- Whilst people are used to the normal yellow colour of a traditional light bulb LEDs come in basically any colour. When looking at colour you can look to the Kelvin (K) scale for indication - the higher the Kelvin number the colder the colour. The scale ranges but one can generally understand it by up to 3000K as being a warm white, 3100-4500K as a cool white and 4500-6000 and up as daylight.
