The City of Gatlinburg’s commitment to convert the Gatlinburg Winter Magic Celebration lights program to 100 percent LED bulbs during 2008 has paid off in immediate and significant savings of electricity (not to mention reducing the City’s carbon dioxide emissions). LED lights use as much as 75 percent less energy, last ten times longer, produce (i.e., waste) almost no heat, and are more durable than glass bulbs. The City — like millions of Americans — have discovered that going green with LED lighting saves green and helps preserve the environment.  As I write about in ECOpreneuring, the “greentech” or clean tech sector, of which LED lighting is but one such technology, is booming.

1. Total # of bulbs;
2. Wattage of the individual individual incandescent bulbs to be replaced. (C9s are generally about 8-9 watts; C7s are generally about 6-7 watts; and mini lights are usually between .50 and 1 watt;
3. Amount of time bulbs will be illuminated; and
4. The average cost of a kilowatt hour of electricity in your area. ($.10 is typically a safe number.)

Step 1: Calculate total watts

Multiple the total number of bulbs by the wattage of 1 bulb. This equals the total watts of the display

Step 2: Enter data into conversion calculator

Enter the product of the formula in Step 1 into the “Watts” field in this calculator. Next, enter the total amount of time the lights will be illuminated in the “Time” section of the calculator. (Note that the time can be in seconds, minutes, hours, days, months, or years.)

This calculator will calculate the total kilowatt hours consumed by this lighting display.

Step 3: Determine cost of electricity

Multiple the total kilowatt hours the display will consume (as determined by the calculator in Step 2) and multiple it by the average cost of a kilowatt hour of electricity in your area. The Department of Energy website has statistics on the average cost of electricity.

Step 4: Determine to cost to operate Christmas lights using LEDs

Repeat steps 1-3. The average LED holiday style light is between .05 and .07 watts.

Step 5: Calculate the savings

Subtract the cost of operating the LED lights from the cost of operating the incandescent lights. This is the total cost savings you can expect by switching to LEDs.

We sent a free set of LED Christmas lights to the first 100 participants and the remaining participants who submitted their lights to us before January 31, 2008 will receive a coupon.   For those of you who participated, thank you for helping us make the program a success and you can expect your coupon to arrive via email or regular mail within the next month.

We are going to expand the program next year and substantially increase the number of sets we give away.  We are also looking for people or organizations who may be interested in participating in next years program.  We will be looking for groups willing to set up collection sites as well as sponsors who may be interested in helping us develop a Christmas light exchange program.   Please contact us if you or anyone you know may be interested.

So far the company reports that it has recycled over 3,000 pounds of incandescent holiday lights which it received from several hundred participants. Anyone who is looking for some place to send their old Christmas lights to die can mail them to HolidayLEDs.com for recycling.

And because I know it will be asked, the lights are sent to a independent recycling company which chops the lights into little tiny pieces using a commercial shredder. The various components (copper, PVC, glass, etc.) are separated and then processed. The lead is extracted from the PVC and shipped to Chinese toy manufacturers who use it to make paint for toys for children. I’m kidding. But I did read a report about a “recycling” company that was actually shipping the old light strings to China where the insulation was manually removed and the copper was extracted for smelting…not sure that this is a net gain.

I’ve been thinking a lot about this issue while evaluating our companies’ recycling program and environmental policy. For the most part our programs have worked well and we’ve had a lot of participation within our organization and from our customers. I think a big part of the effort is just getting people in the mindset of looking for ways to conserve resources and produce less waste. However, I think that once an individual or organization has obtained this awareness it is important to shift focus and attention to refining the underlying processes and programs. For example, we are looking at implementing central collection points for our recycling program so the lights do not have to be mailed to us.

I use this example only because it is one that is familiar to me and to illustrate the point that we need to be cautious in evaluating the net impact of our efforts. This is not to say that we should over analysis this matter and waste untold resources trying to determine which option is more green. In some respects I think there is a substantial and immeasurable benefit to fostering a mindset in consumers towards environmental awareness–even if the net benefit is questionable.

We all need to develop an awareness of the impact our lives have on our environment and the cost of gaining this awareness may mean that some of our efforts fall short of a net environmental gain. However, it is important that we do not loose site of the ultimate objective during the development of this new awareness.

One lesser know alternative to compact fluorescent lights for people looking for energy efficient replacement for their incandescent lights are LEDs or light emitting diodes. LEDs are very efficient as they waste very little energy on heat. LEDs can also easily be recycled and contain no toxic components. LED lights will also outlive even a compact fluorescent lamp by thousands of hours. The downside is that LEDs are still a bit expensive and the technology has not developed entirely so that it is a suitable alternative to incandescent or fluorescent.

However, it has been effectively adapted and applied to lighting applications such as Christmas lights, rope light, and landscape lights. The technology for use of LEDs has been developed well for use in these applications and the cost of these products in an LED is still higher than incandescent but is not unreasonable given the cost savings.

LED alternatives are also available for other lighting types as well. LED replacement bulbs are currently available for MR-16 type lamps that are commonly used in track lighting. LED lamps for the common PAR style bulb are also now available online but have not made it into big box stores and do not quite pack the same punch as their incandescent ancestors.

Lots of cool things are happening in lighting and most of us don’t get exposed to all the options because they haven’t hit the big box stores yet. However, if you do a little research and look around a bit online you can find some great lighting solutions that are more efficient than CFLs and better for the environment too.
