LED bulbs last decades, save electricity, don’t shatter, don’t burn you, save hundreds of dollars, and now offer plummeting prices and blossoming features. What’s not to like? You’d have to be a pretty dim bulb not to realize that LED light is the future…
LEDs last about 25 times as long as incandescents and three times as long as CFLs; we’re talking maybe 25,000 hours of light. Install one today, and you may not own your house, or even live, long enough to see it burn out. (Actually, LED bulbs generally don’t burn out at all; they just get dimmer.)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I have used some LED replacements for night-light bulbs. In that application, I am most interested in longevity, not light output or color (they are a spooky white/blue color). All of my other lamps are CFL. I am not spending $30 for a 60W equivalent bulb. I might consider $10 for certain locations. What I really need is an LED replacement for 8 ft flourescent tubes in my garage. They don’t last long and won’t light when it gets cold.
Although I like LED over incandescent, I don’t see the improvement over CFL. The heat generation due to the AC->DC transformer in the base causes a loss that makes the efficiency little if any better than CFLs, especially at higher lumens.
Now, if we started installing a DC distribution system in our houses, that may be a different matter!
