When I did my research I decided to see if it is worth it to actually upgrade to a LED bulb. I did not want to change the whole light fixture, but was more interested on just changing out the bulb. A LED bulb usually runs at approximately 40W and I wanted to compare it to the average 300W incandescent bulb. I also ran a figure as if the bulb was run an average of 8 hours per day. I also took the national average of $0.15/kWh
What is the running cost of a swimming pool light per year?
300W incandescent bulb x 8hrs x 365 days = 876 KWh /yr at $.15/KWh = $131/yr
40W LED Bulb x 8hrs x 365 days = 116 KWh / yr at $.15/KWh = $17/yr
You save $114/yr
What are the initial cost of a swimming pool light bulb?
Average Cost of 300W incandescent light = $30
Average Cost of 40W LED Bulb = $220
You will make your money back in energy cost savings in 1.6 years ($114 / year)
What are the average lifespan of swimming pool lights?
Avg life of 300W incandescent light - 4.4 yrs
Avg life of 40 W LED light - 11 yrs
Over 11 years you will have to buy 3 incandescent light for every LED light.
Total Savings over 11 year span = energy savings ($114/ year x 11 years = $1254) - initial cost (LED = $220 - 3 Incandescent bulbs = $90) = $1,124
So you will save $1,124 over 11 years.
Bottom line: Should I upgrade to a LED Pool Light?
If you are planning on staying in your home with the pool for over 2 years you will save money on a LED bulb. It makes sense and you will save money.
