lumens per watt

When we talk about purchasing apples at grocery store we buy them per pound (lb). In essence, even though solar power is a more complicated purchase than buying apples, purchasing solar panels all boils down to the cost per AC (alternating current) watt installed. The same rule applies when you buy light bulbs, to figure out if your getting a good deal on a light bulb you must calculate the lumens per watt. Efficiency is an important consideration, but it isn’t the aspect you should look into. So what are Lumens? It’s a measurement of light output from a lamp. When a light bulb produces more lumens per watt of energy input, its more efficient. If you’re looking into purchasing a solar power system by switching to high efficiency lighting, such as LED light bulbs the annual cost savings help to decrease the upfront cost of the solar photovoltaic system. What do you think about high efficiency lighting such as LED technology? Would you buy a light bulb that produced more lumens per watt of electricity used? What is your selection criteria when your shopping for light...

EvoLux and ZetaLux LED bulbs UL listed

Earthled is the leading direct replacement LED bulb manufacturer, recently the company announced their evolux and zetalux product line has received UL listing. This marks a significant milestone for earthled direct replacement LEDs because the UL mark on the bulbs create an opportunity for even more homes and businesses to switch to LED bulbs. The great aspect of LED bulbs are the consume a fraction of the electricity used by incandescent and CFL bulbs and have a lifetime of over 11 years, thus eliminating light bulb replacement costs. LED are very resilient since they’re shatter proof meaning the lens won’t break when a bulb falls to the ground unlike incandescent and CFL bulbs which will shatter when accidentally dropped. I like earthled bulbs because they are direct replacement meaning you don’t need a new ballast or fixtures to take advantage of earthled technology. What do you think about direct replacement LED...

Minnesota looking towards LEDs to reduce costs

With the economy in a downturn, everyone’s tightening their belts, especially local governments. Minnesota’s government is focusing on reducing their energy usage to lower their monthly energy bills. The city of Minneapolis is currently testing LED Bulbs in streetlights, since they make up 40% of Minneapolis’s electric bill. The LED Bulbs that are being tested last 10 times longer than CFLs, contain no mercury (a toxic element found inside CFL bulbs), and only consume from 2 to 10 watts of electricity depending on the size. If the test of the LED Bulbs is successful the city will move forward and replace all their bulbs to LEDs. This test is good example of what you can do at your home or business, LED bulbs reduce replacement costs due to their long lifetime and only requires a fraction of the electricity to operate. What do you think about LED Bulbs? Have you used them? Do you think the city of Minneapolis will see postivie results from their LED...

LED – High efficiency light Bulbs save you money

Many people dream of eliminating their entire electric bill by using solar panels or putting up a wind turbine, although that dream is out of their reach because of the high upfront related with an energy hog’s electric consumption. When you are energy inefficient, eliminating your energy can be associated with a very high upfront cost. Although you have the power to reduce your consumption by looking into energy efficiency there are product out there such as EarthLED high efficiency light bulbs that can reduce your consumption significantly and save you lots of money on electricity costs. LED light bulbs are very reliable, many people don’t know that the average lifetime of a LED bulb is over 10 years! Imagine just the cost savings of not having to replace a bulb for the next 10 years. LED consume only a couple watts of electricity, therefore only cost a couple dollars in electricity costs to run the entire year and their are just as bright at traditional light bulbs. The case study above shows a building that replaced 1100 light bulbs with EarthLEDs, not only did the building actually lower the temperature in the building by a couple degrees, but the amazing aspect is that they are saving 450kWh a day! Based on the cost of electricity of 10 cents per kWh and comparing it to the total cost of 1,100 EarthLEDs the building would break even within 5 years on their investment. The calculation did not include the cost of changing light bulbs or factor in energy inflation and rebates received for high efficiency light bulbs, with those variables factored in we’re looking at a break even point lower than 5 years. Why not CFLs? Well, CFLs have a lower upfront cost, although they also include mercury with is a pollutant that is bad for the environment and CFL light bulbs are not as efficient as LEDs, plus you have to replace CFL light bulbs more often. Taking those points into consideration, the LED light bulb does make more environmental and economic sense. Lighting is typically 10% of the electrical demand of a building, by using LED lights to lower your consumption first in the future you would need to buy less solar panels or wind turbines to eliminate your electricity bill. It’s always more affordable to reduce energy consumption then produce your own. Solar Panels and LED lights make a very cost effective partnership. So what do you think about LED bulbs? looking forward to your...

Solar Panels and Pumpkins? Happy Halloween!

Boooo! Today is Halloween, millions of people across the US are going to enjoy pillow cases overflowing with candy and the ghouls n’ ghosts are going to come out at night. This year is going to be different because more people are using renewable energy to get them through the night. Trick or Treaters need flash lights to stay safe in the dark, this year more people are using solar powered flash lights, charge it up during the day and use it all night. Combining solar with LED light bulbs can be a very effective combination, since LEDs are very efficent, they only use up a couple watts, a small solar panel could power could provide enough power for a night of trick or treatin’. The solar Halloween pumpkin statue is another example of how people are using small solar panels and LED lights to power up their pumpkins this year. Its quite simple how it works, the solar powered pumpkin has a rechargeable battery enough to power the LED inside the pumpkin and will automatically turn on at sunset, glow for up to 8 hours if fully charged during the day. Generally, one of the biggest advantages of using LED light bulbs is their long life time, the LED within the pumpkin has a lifetime of 100,000 hours! Another interesting story I heard between the relationship of renewable energy and Halloween on this week’s Inside Renewable Energy Podcast by Stephen Lacey of featured a special guest named Jake, a 9 year old who decided to dress up as “BioFuel Man” to educate others about the benefits of renewable energy on Halloween in his community. How amazing is that? The purpose of this post is to point out the little applications and grass roots promotion in the local community level of renewable energy end up making a big impact. For example, many people who don’t understand how solar power works, could have a basic understanding by just looking into a solar powered pumpkin. The end goal would be just to get them to thinking about how renewable energy can be applied to other aspects of their lives, such as using solar panels to power their homes or filling up their tanks with renewable fuels. Happy Halloween! Stay...
