The 4 Best Energy Efficient Light Bulbs – Save Money the Easy Way

The 4 Best Energy Efficient Light Bulbs – Save Money the Easy Way: When trying to save extra money, sometimes you need to look at the small details. In this case, we’re taking a look at energy saving light bulbs. Prior to 10 years ago, everyone used incandescent bulbs. Incandescent bulbs are dated and inefficient technology with average reliability. Thankfully, the market has stepped up and begun to release new bulbs that are brighter, require less energy and that last longer.

What to look for when picking out the best energy efficient light bulbs

Typically, energy saving bulbs fall into two camps: CFL bulbs and LED bulbs.

  • CFL bulbs use about 85% less energy than a comparable incandescent bulb. They also last 10 times as long with an anticipated lifespan of 1,000 hours.
  • LED bulbs also use about 85% of the energy of an incandescent bulb but these bulbs can last between 25-30 years! This is due to the fact that they contain no filament that would burnout

When picking out energy saving light bulbs, they may display their strength in lumens vs. using watts like everyone is used to. Thankfully, I found this handy charge that explains the conversion of Watts to Lumens:

Basically, most people will want to stick with a bulb in the 700-1300 watt range.

Kelvins: What they mean and what to watch out for: With some of the light bulbs you will encounter things like “5000K” when referring to the type of light. What this refers to is the amount of whiteness to the light that bulbs produce. Recommended light ranges are between 2700-5500K. The lower the number the more “warm” the light tone will be and the higher the number the more “white” the light will be.

How much can you save by switching your bulbs?

After browsing around for a little bit, I came across this interesting blog which had an example of the potential savings:

Let’s say you have 40 light bulb sockets in your home all using 60-watt incandescent light bulbs. Let’s also assume that you use 2,000 hours of electricity from these fixtures annually and that your utility company charges you $0.11 per Kilowatt hour.

40 (Number of Bulbs) x 60 (Wattage of Bulbs) = 2400 Watts (Total Wattage)

2400 (Total Wattage) / 1000 = 2.4 Kilowatts

2.4 (Kilowatts) x 2000 (Hours of Usage Annually) = 4800 Kilowatt/Hr

4800 (Kilowatt/Hr) x $0.11 (Cost of Energy per kWh) = $528.00 per year

Now, let’s say you are planning to switch your original bulbs out with 14-watt CFL bulbs that are 60-watt incandescent equivalents. Using the same information, such as the hours of usage and the amount you are charged per Kilowatt hour, it would look something like this:

40 (Number of Bulbs) x 14 (Wattage of Bulbs) = 560 Watts

560 (Total Wattage) / 1000 = 0.56 Kilowatts

0.56 (Kilowatts) x 2000 (Hours of Usage Annually) = 1120 Kilowatt/Hr

1120 (Kilowatt/Hr) x $0.11 (Cost of Energy per kWh) = $123.20 per year

So if we want to look at those numbers more closely, you have a possible yearly cost with incandescent bulbs of $528/per year vs. $123.20 per year with LED bulbs. Huge difference!

I did this exact thing when my wife and I moved into our new house. The previous owners had installed recessed lighting throughout the downstairs. While it looked great, the issue was that each of these lights was using a high watt incandescent bulb, somewhere in the realm of 60-80 watts per bulb. The worst part? There was a total of 44 lights downstairs.Switching to LED bulbs definitely dropped the monthly electric bill. The other great feature is that the bulbs I bought are dimmable as well to further cut down on the power usage!

Conclusion: Best Energy Efficient Light Bulbs

From the list of the four bulbs I mentioned, the most efficient has to be the Sansi bulbs. With the 5 watt power draw and lower Lumens, this is the choice for the most efficient overall. The most cost effective would have to be the Tenergy LED light bulb. In your search for the best energy efficient light bulbs, I would really have to hand it to the Sansi bulbs. Not many things beat that 5 watt power draw.

Either way, you can’t go wrong with any of these choices. These bulbs will pay themselves off with the savings they will provide! Good luck and happy saving!

  1. I love all the simple and small ways to save money. Switching out light bulbs to energy efficient ones is definitely something that is not too hard to do at all. I’m thinking of purchasing a bulk lot at a discount, then I can switch the lightbulbs as needed. Though with how long LED lights last, I better make sure I don’t buy too many!

  2. Had no idea of just how much saving can be had from a light bulb …what an eye opener makes perfect sense to me to switch seeing the charts WOW!! I m blown away. I used to bulk at the cost of LED but they do tend to last forever. Great article.

  3. I have switched to using the energy efficient bulbs, I use the ones that look like the Philips Fluorescent bulbs. Not only have I noticed a difference in my electric bill, but the other bulbs burned out at a very fast rate, these new energy efficient bulbs are lasting longer. 

    When I made the switch, I bought the same amount of energy efficient bulbs that I would normally buy of regular bulbs, which is one for each socket, and a back up for each. It has been almost two years now and I have not had to change a single bulb yet! 

    So they may cost a little more on initial purchase, but it is so worth it! I would have spent way more on the other bulbs just replacing them, and the extra energy consumption on top of it. 

    Great Product!

  4. I like your suggestion on saving electrical power by choosing the right source for our light.

    I personally don’t want to have less lumen though, I need it bright inside some rooms where I work or study.

    I now use the Philips Energy Saver Compact Fluorescent T2 Twister Household Light Bulb, one of these equals 2 Sansi bulbs, ok it uses a little bit more energy but at least the buying expense is quite a lot cheaper.

    These CFL bulbs are very effective, just don’t try to take one out while still hot, they’ll break.

  5. Hello,

    This is a very informative article. I learned so far about use life of LED bulbs that I did not know. I am used to thinking it lest 5 years, but is wonderful to know they can last 25 to 30 years. Remembering about 9 years a go, my husband decide to change all bulbs for LED ones, and I was against, because I did know better. Latter one. I learned we could save so much in energy, I became addict to Led lamps.I am amazing to see the saves you are showing us. $528/per year vs. $123.20 per year is a huge and considerable saves that anyone can do (I understand this is am example). If we compare the regular old 60-watt incandescent light bulb we used to buy, of course we are paying more for the Led bulb, but the saves with my electric bill can cover this cost for sure and much more.What a powerful and helpful information you gave to allot people. Thank you so much.

    To your success,


  6. It’s absolutely amazing to see how much the simple light bulb has evolved over the years and even more so, how a simple light bulb can actually save you money. My townhome community a couple years back replaced all of your main bulbs with the LED once and I have noticed it has saved me money over the course of time. 

    For my other bulbs, I have used the Philips Energy Saver as they seem to last a very long time. I noticed your recommendation was for the SANSI. I actually never heard of these. In your expert opinion, how are these better than the other 3? It also says they are dimmable? How does that work with a light bulb? 

    Great website by the way – and thanks for sharing this info. 🙂

    1. I think the best features are that it’s dimmable but also the low watt power draw definitely is a plus. The Sansi is 5w vs 8-10 for most of the others. It may not seem like a huge difference but it’s basically half of what the other ones are. I’m sure there are even more savings to be had!

  7. Dave I agree that energy efficient bulbs are the way to go.  I changed to LED when I remodeled my kitchen, yet in my bathrooms I need new fixtures as many people do who have homes25 years or more old. These bathrooms have the none covered globe shaped bulbs. I have reduced them from 60 watt down to 40 to reduce the bill. other lamps all have LED. Good comparison of cost saving on the chart. Thanks

    1. No problem. I’m slowly converting my whole house to LED bulbs. The big change is when I switched out all of incandescent bulbs in my recessed lighting to LED. It was 44 bulbs all at once so the savings were pretty noticeable!
