One can rarely fail to notice the change from incandescent bulbs to compact fluorescent lamps. Perhaps very essential is the development of LED lighting which is better for the environment and considerably less costly over the life of the bulb. LED bulbs last much longer than any other type of lighting and they use up only a fraction of the electrical energy which other forms of illumination perform.
Research funded by the US Army Research office has found out a way to improve both lighting and stability. LED lights employ a gallium nitride film in building the diode that produces the light. A completely new technology, developed in North Carolina, reduces the defects in the film notably. Additionally, the new film permits the diodes to produce more illumination – up to twice as much.
The deficiencies are removed by deliberately setting a void within the film. Defects in the crystalline composition of the GaN film are drawn to the voids, stopping them from running through the full thickness of the product. Using the voids decreases these defects by 90%.
The Future Looks Bright
This development is expected to help trim down the price of LED bulbs in the next 5 years. By strengthening production, waste will be dropped off; less waste equals greater profit potential for fewer supplies, and a commensurate reduction of cost.
It is a bit hard to swallow the idea of paying nearly $20 for a single light bulb, especially after ages of seeing incandescent bulbs work $1 a piece. CFL bulbs cost less, but they aren’t problem free either. The mercury found in each bulb may be minimal, but crack one in your home and clean up is a pain, and those that make it by trash collection inevitably break in landfills, making a potential ecological disaster. LED lights may be expensive up front, but the pay off is crucial.
Looking at the entire Costs
When you look at the charges for a light fixture you have to think about bulbs and electricity. Breaking down the costs of incandescent lights, CFL bulbs and LED bulbs, you obtain the following analysis, based upon a projected cost per KWh at $0.13 – the countrywide average.
Expecting 6 hours of effective use daily for a single 60 watt bulb or its counterpart and estimating 60,000 total hours of use, and a realistic lifespan for a LED bulb, the statistics are as follows. Running and supplying incandescent bulbs would charge $482.61, the CFL bulbs $119.52 and the LED bulb, $96.80. Imagine how those reductions would add up if you transform the majority of your bulbs from incandescent.
Solutions to Get a Bit More for Your Money
The price differential is apparent; LED bulbs are the most cost effective, although CFL bulbs are a comparatively close second. LED bulbs have the advantage of not having any mercury, which makes them worthy of serious thought. To get the best LED bulbs start by selecting Energy Star products.
Choosing Energy Star compliant bulbs will decrease your energy use per lamp fixture by at least 75%. The bulbs operate with standard dimmable switches, don’t break easily, are guaranteed for three years which are expected to last up to 22 years with continuous service.
Call your local power company and ask if they are offering any refund programs to people who buy LED bulbs.
Get on the web and order bulbs directly from the manufacturing businesses if you can. They are often less expensive than those sold at home supply stores or supermarkets and the choice is more extensive. Finally, try to remember that acquiring LED lights is a long term investment – this will pay off.
