Mine are made by Utilitech, sold at Lowes. I had to do some adjustments on them and they run hotter than incandescents probably due to all the ceramic. They are well built and heavy. If they hold up to their advertised life I will get at least 12 years from them.

1) ISTR LEDs run at about 5VDC (do they even work on AC?) and very low (VERY low) wattage. Hence the savings.
2) One HAS to step 110/120VAC down to ~5volts (and DC?) so there has to be SOMEthing in the bulb base to achieve that. What is it? Transformer? Transistors for AC-to-DC? Selenium rectifiers (does anyone even use those any more)?
Is the circuitry (?) garanteed as long as the LED? I ask because my neighborhood is known for outages and surges; not clean power.
