December has arrived, it’s time to rummage thru our garages and attics to find our Christmas decorations. The light intensity of American suburbs increases by 30 to 50% each Black Friday evening as Americans adorn their homes and landscapes with Christmas lights. It’s an annual phenomenon originally reported by NASA.
All this extra lighting comes at a cost though, right? How much does that illuminated Reindeer will really cost? We know that LED lighting is more efficient than traditional incandescents, but by how much? Well, if we were to take some common holiday lighting – say a string of 25 C9 bulbs (the big plump ones that are typically put up outdoors), that string would use around 175 watts of electricity over 12 hours, which over the season translates to around $15. But a string of C9 LED bulbs by comparison uses 2.4 watts and, over the same time period, would only cost around 21¢. Sure, that’s a big saving but 25 lights aren’t really going to win you most joyful. So, let’s say you have 4 strings making 100 bulbs; well, that would cost you over $60 for the season compared to only 80 cents for the LED equivalent. That’s a pretty big saving for any time of year.
Now think about the lighting you use in your school, your office, your hospital, your car dealership every day of the year. Can you imagine the savings that you could achieve by switching to LED lighting? Well thankfully, you don’t have to imagine. You can just talk to the Tenzing lighting experts who will be able to tell you exactly how much you could be saving, and how long it will take for your investment to pay for itself. Which means you can start thinking about how many more Christmas decorations you could afford next year!
