Quite often I’ll get in to debates with friends and family about energy and we end up in conversations about why we choose to be a three Prius family and why I’m so hot on the Internet of Things and my investment in SmartThings‘ technologies. Where it gets tough, however, is justifying why we are replacing our incandescent light bulbs (and even compact fluorescents (CFLs)) with LED light bulbs since the costs of LEDs are still a bit high.
That LED bulb cost makes the return on investment (ROI) a little tougher to justify for purely economic reasons, except when you consider that one LED will last for ~25,000 hours and an incandescent for only 750-2,000 hours.
LED costs are coming down but, like my friend Eric said to me just last Friday, trying to time the purchase of doing a wholesale incandescent lightbulb replacement in your home is like “catching a falling knife.” Buy too early and you get hurt since the break-even will take too many years, though I’ll argue that the time is now to begin replacing incandescents (and CFLs) with LED bulbs.
For my wife and I it’s not just about cost, however. We strive to do our bit to minimize our energy footprint and try to positively impact human’s effect on the climate in a myriad of ways such as recycling more than anyone in our neighborhood. Our lightbulb replacement adventure is just starting but will add to our objectives of minimization. Every little bit helps.
So let’s take a look two examples of bulb replacement in my own home to give you a sense of what I’ve already done and what the results have been so far. Hopefully this will help you determine whether or not the time is right for you to “catch the knife” and replace your incandescent bulbs with LEDs.
