I just moved into my new home last week, and of course one of the first things you do is have to fix a lot of little broken things. First problem, MBR ceiling lamp not working. Fault isolation: no bulb! Second problem, wardrobe ceiling lamp not working. Fault isolation: no bulbs! What a cheap [censored]!!! What kind of person sells a house and takes the light bulbs with them?
So it got me on the topic of getting new bulbs. I had a bunch of CFLs in my storage unit, but location unknown. (I found them today.) So I was at Costco and bought a few 4-packs of CFLs, but was intrigued by the new LEDs and I noticed they'd dropped in price since the last time I looked (a few years ago). My new home has about a dozen can lamps (spot lamps recessed into the ceiling) so I bought a few CFL spots, brought them home and tried them. They were great!!!
Before I get to the meat, here's some background. Tungsten lamps have been around since Thomas Edison. There's a bit of quibbling among historians about who/what/when, but Edison patented a light bulb essentially as we know it today in 1878. But there was a basic problem with incandescent light bulbs. They put out more heat than light. They waste huge amounts of energy by turning it into heat, not light. Good in the winter, not good in the summer.
So many decades later fluorescent lamps were invented, much less heat, much more light. More time passes then CFLs are invented, a thin fluorescent tube curled up to resemble the common screw in tungsten light bulb. Much better! Now we have light bulb that are not primarily heaters but instead produce mostly light. Not only do they use less energy (by not making heat) but they last longer too. They're more expensive but the TCO (total cost of ownership) is cheaper. If you replaced every light bulb in your house with CFLs you'd save money and have to switch them less frequently.
But still there were problems with CFLs. They weren't dimmable and they've got that nasty toxic mercury in them, bad for the environment, bad for us when we break one. Later on the manufacturers made some of them dimmable...
LEDs were invented decades ago--remember the first calculators? I bought my first calculator in the late '60s, basic functions and over $50! LED light bulbs has been a holy grail to the lighting industry since then. After much inspiration and perspiration LED light bulb replacements were developed about a decade ago but holy [censored]!!! they were EXPENSIVE!!! And not dimmable either.
Fast forward to present day, LED light bulbs are now both affordable (although somewhat expensive, but considering TCO it's a great deal) and many of them are dimmable. The age of affordable LED lighting has arrived. In fact it's cheaper for new construction to use LED lighting than fluorescent since fluorescent recessed lamps require ballasts (technical term, google is your friend) and I presume contractors are being pressured to not build new houses to use tungsten lamps.
Part 2: my experiences replacing a whole house with LED. I'm saving this post in case the forum gremlin comes along and erases my entire post. (That sometimes happens on all forums.)
