Have you ever wondered what would actually change if you switched to LED? You are probably too accustomed to the CFLs or tungsten lights you use right now, never done a long-term cost analysis and do not really imagine what kind of changes switching to LEDs will bring.

Let`s do a general cost analysis and compare the results of LEDs, CFLs and tungsten bulbs. I will take an electricity cost of 10 cents/KW and an average of 4 hours of light on per day, which means about 15000 hours of operating hours in ten years.

Let`s take the common tungsten lights first. If you have 10 incandescent bulbs in your small office, you will spend about $7.50 to purchase them and have an annual operating cost of approximately $84. Take into consideration that incandescent bulbs will be around for only 1000 hours (500 hours if you are lucky). There is also the additional cost generated by the fact that the air-conditioners will work harder to compensate for the heat emitted by the bulbs. Let`s see what happens in 10 years. In ten years, you will need to replace the light bulbs each year so in total you will spend $75 on the purchase and $840 on the bill, so $915 in total plus maintenance costs.

If you have 10 CFL`s in your small office you will spend about $110 to purchase them and have an annual operating cost of approximately $23. CFL`s will last for almost 10000 hours but they contain mercury and that could be a problem if you have people working for you and a hazard for the environment. If it is very cold or the lights are placed outside in the cold, they will need a couple of minutes to turn on and in some cases, they might not even work. Let`s see what happens in 10 years. In ten years, you will need to replace the light bulbs once and in total, you will spend $220 on the purchase and $230 on the bill so $450 in total plus considerable maintenance costs.

Now let`s see what happens if you have LED instead of CFL or Tungsten bulbs. If you have 10 LEDs in your small office you will spend about $390 to purchase them and have an annual operating cost of approximately $80. LEDs last will last for at least 50000 hours in any environment, whether is cold or warm, whether they suffer physical shocks or vibrations. Let`s see what happens in 10 years. In ten years you will not need to replace the LEDs and in total  you will spend $390 on the purchase and $80 on the bill, so $470 in total, but you will have no maintenance cost.

As you can see, it seems that incandescent bulbs are no option as they are the most expensive ones on the long term.

The first impression is that CFLs might be a little bit better than LEDs as the overall cost is a little bit lower (not counting maintenance costs).  The thing is that CFL will need another two or three replacements in the next years, while the LEDs will work just fine. In addition the maintenance cost will rise with the CFLs. CFLs are also a bio-hazard, they do not work always, take up a lot of space and give an unnatural light, so there are quite numerous advantages to LEDs when we compare them to CFLs so the slight disadvantage of LEDs in the first years can be easily ignored. Moreover, in 12 or 15 years the LEDs will prove to be more economical than all the other options.

Do you find that your home’s indoor air is extremely dry? Are you frustrated by dry skin and sore throats during the winter time? Do you need something a bit more comprehensive than the small humidifiers that you can buy at the local hardware store? If you own a central air unit/furnace combo or a heat pump, then you also have a network of ducts installed in your home. A whole house humidifier may be just what you need to ensure that your air is optimized when it comes to the humidity level. Dry air can disrupt your comfort and aggravate health issues.

This year I’m seriously jazzed about the 2012 Emmy nominees – especially for Outstanding Lighting Design. Admittedly, I’m a sucker for theatrics (dating back to long before those college stage makeup classes and my Cirque du Soilel-level Halloween costumes) but honestly, these nominees are amazing. Here’s what the Academy has laid out for us this year:

Outstanding Lighting Design/Lighting Direction For A Variety Series

So You Think You Can Dance

Last year’s winner is at it again, producing number after flashy number. Lighting designer Robert Barnhart along with lighting directors Matt Firestone, Pete Radice, and Patrick Boozer are ones to beat, for sure. Check out this dramatic jazz piece from the Season 8 finale, it’s truly unforgettable:

Dancing With The Stars

This show is a first time nominee in the category, but lighting designer Simon Miles and lighting directors Matthew Cotter and Suzanne Sotello are definitely ones to watch out for. Check out this Halloween-themed Paso Doble featuring Ricki Lake, and you’ll understand why this lighting team has earned a coveted nomination:

American Idol

This program won the title in 2009, and this year the same team of lighting designer Kieran Healy, and lighting directors Joshua Hutchings, George Harvey, and Matthew McAdam are at it again. This highly talented group might just have what it takes to win again. See for yourself in this clip of Phillip Phillips (season 11 winner) singing at the Idol finale:

The Voice

Another newcomer in the category, The Voice has really made a splash in its second season. Lighting team Oscar Dominguez (designer) and Daniel K. Boland (director) have made sure that the voices aren’t the only remarkable thing about this show. Check out this video of season 2 winner Jermaine Paul (from team Blake) and you’ll see what I mean:

LEDs are at the forefront of light industry discussion because they are such a gamechanger when it comes to energy efficiency and lifespan. But how do recent developments to LED technology affect the everyday consumer? What’s the simplest way to navigate this uncharted territory when shopping for LED light bulbs? The very recent availability of an LED replacement for the common household incandescent lamp has created a world of new potential, and along with it a whole new set of standards. In this post, we will be discussing the various ways to distinguish between the different LED options.
