Opt for LED lights and Save Everything at Home

Original post made by gracedan, Livermore, on Oct 9, 2013

It is a known fact that saving money will not just happen when a business or home reduces the amount of power that they consume. Always bear in mind that savings must include environmental awareness as well as the overall future on financial savings. In any home, there are many appliances and electrical equipment present. All of these contribute to your monthly energy bills. If you want to save energy and your money, it is best to start with the in your home. Throughout the years, finding lighting solutions that are both cost-effective and helps save energy was made possible with the introduction of the energy-saving LED lights.

In terms of the consumption, many homes have lighting units that have greatly contributed to the consumption of energy. The efficiency of lighting is basically measured from the degree of brightness that a specific source can produce as well as the amount of energy needed to generate that light. Take note that the overall lifespan of the lighting source is also considered as a determining factor. At the present, there are major improvements on lighting efficiency that are now used such as the replacement of fluorescent and incandescent with energy-saving options. Nevertheless, many homeowners can further improve these by utilizing LEDs that are considered more efficient unlike with other lighting fixtures available in the market.

We will now take a close at this energy saving option. LED basically stands for light emitting diode which is a type of semiconductor that generates light once electricity passes through it. Take note that the energy gap present on the semiconductor helps determine the color of the light that a particular LED produces. It simply means that the light colors that can be produced can range from several hues as well as those that are not even visible. The installation of several energy-saving lights in a single or series enclosure can drastically boost the intensity of the light.

Due to the latest developments in the manufacturing of LEDs, it made the production process less costly and easier to produce. It is a known fact that the LED lights today are highly versatile and more dependable than the earlier versions. LED light bulbs can easily replace fluorescent lamps by providing the same amount of light output but with a lower energy requirement. Take note that the LED strip lighting is considered flexible and can be used as a replacement to colored fluorescent lamps as well as neon lighting.

The best part about these energy-saving LED lights is that they can provide a decent intensity of lighting but at a lower energy requirement. If your home still uses fluorescent or incandescent bulbs, it is time to opt for the LED options since they can help lower down on the consumption of electricity while at the same time enjoy better lighting. The energy consumption in your home will drastically drop if LED slights are used instead of other options in the market, thus allowing you to enjoy lower energy bills.

I like LED lighting and have quite a few LED bulbs in my house, particularly in heavily used locations. LEDs do use significantly less power than incandescent lights (about 5x less). However, the claim made in this article that LED lights use less electricity than fluorescent lights is inaccurate. The amount of electricity used by current LEDs is about on par with fluorescent lights. I still prefer LEDs over fluorescents but because of the better lighting color, faster startup, and longer life, and not because of any energy savings over fluorescents.

Agree with Sam. Fluorescent and LED are about the same as far as energy usage goes. The one thing that is bad about fluorescent lamps is that they contain mercury, which is of course toxic to the environment and makes fluorescent lamps harder to dispose of. Also it can be difficult to start fluorescent lamps in cold weather. LED lamps are environmentally cleaner, both in manufacturing and disposal, and are not sensitive to temperature. Also LED lights, unlike fluorescent and incandescent lights, do not give off ultra violet(UV) radiation. In fixtures used outside this is a plus for LED lamps because most noturnal insects are attracted to UV light.

LED's are great, provided you purchased the right color spectrum, choosing one as close to incandescent bulbs as possible.

Sam, you're wrong about the energy usage versus fluorescents. LED lights are twice as efficient as the dreaded mercury filled lights the govt was promoting until recently. Please see the comparison chart at this URL: Web Link

"Right", thanks for the link. It does appear that the tables on the website you provided show that LEDs are about twice as efficient as CFL's (compact fluorescent lights), but this is the first website I've ever seen to make that claim. I checked out various sources of information when first investigating the possible use of LED's in my house, and they consistently indicated that the energy usage of LED lights are in the same range as CFL's. For example:

Web Link (See LED vs. CFL comparison of lumens-per-watt in the middle of the page).

Web Link (See "white LED" vs. "Compact Fluorescent" comparison in the graph.

Of course, fluorescent lighting is a mature technology, whereas the technology behind LED lighting is improving from year to year, so it would not be surprising if future LED lights significantly outperform CFL lights in terms of lumens-per-watt. Also, it's possible that some manufacturer currently has some ultra-efficient LED (which is also probably ultra-expensive). But for common LED lights that you are likely to get at Home Depot, I think that you'll find that the energy efficiency is about on-par with CFLs.

(P.S: It's interesting to note, though, that the Madison Gas & Electric website given above shows linear fluorescent style bulbs outperforming both LEDs and CFL's in terms of lumens-per-watt. Of course, linear fluorescents are more often found in industrial settings than in homes.)

I'ven recently purchased LED bulbs at costco for about $29 (I think for 3 bulbs) and the expected light is 22.7 years or something like that. I've used them to replace canned lights and regular lamp fixtures through out our home. I actually really like them and the color spectrum is not bad either. Also, we use LED lighting in our business in Pleasanton and have had sophisticated modules installed that use LED lights so we have seen a tremendous savings on our energy bill there (used Xicato lighting modules). The fixtures where not inexpensive but the technology is better for the environment, it is better than fluorescent lighting and the effects it has on one's health, including the skin--we're in the day spa business--and the lighting effect is lovely. What can I say, we're LED all the way!!

At some point moving to LED's is the way to go.
But not for the political correctness.
1.6 mil to save 200k per year.

I ask why now.
If the cost of LEDs continues to drop as it has over the last few years could we do the same project in 2 years 800k?

$1.6 million to switch to LED streetlights with a resulting savings of $200K per year doesn't sound too bad to me. That means that changing to the LED streetlights should about pay for itself after 8 years. And after 8 years, it means about $200K per year in savings to the city up until the life expectancy of the streetlights.

As for delaying the project, I don't think that the prices of LED streetlights are going to drop by 50% in two years. Even consumer LED lights (for which there are a lot more manufacturers and a lot more price competition) are probably not going to drop by 50% in just two years. Also, remember that putting off installing LED streetlights for two years means that the city would not be getting the $200K in annual savings for those two years. Delaying the project by two years would only make sense if one expects that the cost of the $1.6 million streetlight system two years from now will be less than $1.2 million (i.e., at least 25% less than the present cost).
