So it looks like in terms of cost, LED is now to the point where it is the smart buy if you consider your time valuable at all (how much time do you want to spend changing light bulbs?). The energy expenditure might be the same between CFL and LED, but if you figure you need to change a CFL 3x as often, that's 3 times the lightbulb changing events.
Also, it seems like we are reaching diminishing returns outside of potential manufacturing efficiencies at some point in the future. How far can we go to make lighting efficient until it makes more sense to focus on other areas of energy consumption like the systems that manage your lighting or other home/office utility infrastructure like the Nest thermostat?
- ruswick 13y agoUnless there is some sort of significant impediment to changing a bulb (eg. a covered fixture), it takes 30 seconds to a minute maximum to change a bulb. It will probably take everyone reading this more time to read the article and participate in this thread than it will to change every light bulb in their house for the next decade. It's negligible. There are many things to take into account when purchasing bulbs; chance are, the time it takes to change them is not one.
