Christmas Lighting



So how can we save money from the Christmas lighting?


Now there are two types of lighting available the mini bulbs and the LED lights.


Mini Bulb:






Led Bulbs:




Let’s consider you use mini bulbs ( 0.4w) for 8hrs a day. Then it will consume 1.6kwh per day. Now for a month it will consume 48kwh.  Ie it will cost you around $5.76 for the month ( ie assuming $0.12 per kwh electricity bill)


Let’s consider you use led bulbs ( 0.1w) for 8hrs a day. Then it will consume 0.4 kwh per day. Now for a month it will consume 12kwh.  Ie it will cost you around $1.44 for the month ( ie assuming $0.12 per kwh electricity bill)
On checking the prices of the bulbs the mini bulbs are around $15 less than LED lights per 500 bulbs.


 Ok so as you see we don’t save, if you use the 500 LED bulbs for one holiday season. But if you consider using for 5 holiday seasons i.e., In 5 year period, your LED bulbs will cost the initial $15 dollars extra than the mini bulbs and $1.44 * 5 for the energy bill. That totals to a $22.2 instead of $28.8 used for energy cost when using the mini bulbs.


 So what is the best time to buy these lights? Of course it is after Christmas there is a huge sale on the light bulbs. As the merchants hike up the prices before Christmas and now they have to get rid of the excess stock of lights. So now you can buy these lights at a much reduced rate.
