LED lighting is one of those things where you have to consider the quality before you look at whether or not you are getting the best bang for your buck. As mentioned, “in this instance cheaper isn’t always better!”
The lifetime of LED lighting is one of the largest reasons that it can be beneficial to make the investment. If you replace your RV lighting with quality LEDs you will never have to change them again you end up saving money at the end of the day if you have gone to the effort to buy quality bulbs – you get what you pay for.
The other thing that makes LED lights worth the investment is the amount of energy that they use. Both Dack and Daoust mentioned the significant energy difference between LED light bulbs versus classic incandescent bulbs. LED lights can draw up to 90% less power and use only 2 watts/hour, compared to incandescent lights that use 20 watts/hour. This is a huge difference and you will really begin to notice it especially if you enjoy doing a lot of boon docking or dry camping.
