Over the course of the last 50 years we have been starting to use more energy efficient items. Christmas decorating and lighting has already taken one step toward energy efficiency, its just no one really noticed at the time, because the next stage in lighting was just a cool thing. How many remember the old bulb lighting, the kind that use to be on your grandparents and parents Christmas trees when you were little? Those big little bulbs cost a fortune and were extremely dangerous. These bulbs used approximately 5 WATTS per bulb. Many used at least two strands to light a tree which was around 500 WATTS of power. These bulbs broke very easy and could cause a fire quickly. Around the early 80's Mini Christmas lights were starting to become popular. These were were a huge savings on energy and also if one bulb went out they all didn't go out as in some of the old styles. Each bulb used approximately .5 WATTS. For a normal strand of 100 bulbs this would be equivalent to 50 WATTS. What a savings! 500 to 50 is a big deal, but energy was cheap, and no one cared so much. It was Christmas time and you didn't have to pay the bill till January so it wasn't as big of a deal. Back then you didn't leave your lights plugged in all the time either. These lights ran for approximately 3000 hours. Its where the "You buy new lights every year" feeling comes from. That is roughly 125 days of continuous use. Sound like a lot? Nope!
And now comes the fun part. The new energy efficient LED Christmas lights........ :)
.05 WATTS per bulb.
Yes that's right 500 WATTS to 50 WATTS to 5 WATTS. Now lets put it into cost savings based on .12 per KW like it is in Syracuse, IN. This would be your cost for 1 continuous day of usage and then a continuous month.
500 WATT / $1.44 / $43.20
50 WATT / $0.14 / $4.32
5 WATT / $0.01 / $0.43
This is only based on 100 bulbs, I know most of you have more then 100 Christmas lights on at your house at Christmas time. How many do you have. Its funny to think about but back in high school it was a game to see how many Christmas lights I could get mom and dad to let me put up. Heck energy was really cheap then (I wasn't paying for it). Sorry mom and dad!
So at last count they had 3000 bulbs inside and outside at Christmas time. They are on a cheaper power company of around .10 per kw. They usually keep their lights on for about a month and a half. This is the comparison between regular and LED.
( 3000 Bulbs X .5 Watts X12 hours ) / 1000 = 18KW per day X .10 = $1.80 / Day $54 / Month
( 3000 Bulbs x .05 Watts x 12 hours) / 1000 = 1.8KW per day x .10 = $0.18 /Day $5.40 / Month
So here is the kicker above everything. These new light fixtures last 22 continuous YEARS of operation. 200,000 hours. How about your current set?
Just a thought!
