Step by Step

Step 1
Upgrade to a LED pool light

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

Step 2

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

Step 3

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)

Step 4

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.

Step 5

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.

Question to all:
I'm lookinmg in changing my current 12volt 300watt bulb to a LED light bulb. Do I have change my 300watt transformer or can I use it with a new LED light bulb?

hey I want to buy an led strip that i can put in my fish tank. The strip just has 2 wire ends and no plug, how would i hook it up to power so i can plug it into the wall outlet? is it as easy as getting a plug from a hardware store and hooking it up to the terminals?

most of the comments refer to residential pool and the cost comparison is based on a 300 watt bulb when most lights are 500 watts. lots of apts have the lights on a photo cell to operate the lights as a security measure. so if you have 6 -500 watt lights @ 8 to 12 hr a day vs an led which uses .17 amps @120 volts 28 watts. this is a big cost savings for a customer like this.

I switched from a 300W incandescent to a 40W RGB Galaxy light when remodeling my pool. I never turned the old light on unless we were swimming because it was so expensive. Now I turn on the color changing bulb for several hours each week. It's just much nicer to look at a colored pool.

This seems to be an ongoing argument. Views can go either way. My personal belief though is you will be saving money in the long run. If you never turn on your light I would recommend not replacing your bulb at all :)

User: 

this is the same flawed logic the gov't uses to justify expenses. We thought about upgrading our lights but when you figure the savings based on more realistic usage for residential pool of just a few hours per week, I just could not justify the cost of LED lights.

We decided to upgrade to LED Colored Lighting after our bulb burned out last summer. After some checking around we went with the Hayward Color Logic light. It fit in where our old regular light was so it was a simple switch out. To say we are ecstatic is an under statement ! The Colored Lights and Colored Light Shows have made the Pool the main focus from our house at night. No more "BIG DARK HOLE" in the backyard. When we have parties at night all everyone talks about is our Color Logic Light and all the different shows it does. My Wife and Kids each have a favorite Color. This may be the best Money we ever spent on upgrading our 14 year old pool.

I don't know about anyone else out there but the less I have to pay to the power company the more I keep. You will have to replace the bulb sooner or later and that is the time to change to led.

The Replacement Bulb for under $220 that I was referring to in the article was the Galaxy Pool Light (in white mode). This is comparable to your 3,000 lumen bulb.

User: 

An incan 300 watt light produces about 3,000 lumens. Where did you find a 3,000 lumen LED light for $220?

User: InyoPools

Yes this is true for most residential pools. However a commercial pool could run 8 hours in a day. I wanted to use the extreme rather then the 30 minutes a day. Obviously if you keep your light off you will save the most money. If you run the light 4 hours a day you will save $57 per year. A 500W bulb will also use more energy then the 300W average bulb.

User: Bill in San Diego

Really? You figured you run the pool light 8 hours? So if gets dark at 7:30pm and you turn the light on you then run it till 3:30am. Sounds fishy to me. I've had the same 500W bulb in my pool for 10 years. Granted I don't even turn it on most days.
