Digital Life-Tech Test-Smart LED Bulbs

The The Royal Swedish Academy of Sciences and I have one thing in common: We both love LED lights. The Nobel committee today awarded the three scientists who perfected the light-emitting diode the Nobel Award for Physics.

"The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: Due to low power requirements it can be powered by cheap local solar power," the Nobel committee said.

I've loved LED lights since they've dropped in price from a stratospheric $20 for a 40-watt equivalent bulb to about $10 -- still a lot for a little light, but worth it because it lasts virtually forever.

Here are the five reasons why, as my incandescent bulbs burn out, I replace them only with LEDs:
1. LEDs last from 30,000 to 50,000 hours. That means if you install one LED bulb today, and burn it for about three hours a day, you won't have to replace the bulb until 2041 -- at the very soonest.
2. LEDs give bright and instant light, unlike slow-glowing CFL bulbs that make rooms look darker when you first turn them on.
3. LED bulbs can deliver a wide range of light "colors," from sunlight-bright to a warm, yellowy glow.
4. LEDs eventually save money. HouseLogic says the average homeowner would save $100 per year by switching totally to LEDs.
5. LEDs are way cool. Philips makes a "Hue" connected bulb system that lets you wirelessly control the color and intensity of its light. You can go from bright bluish light to a romantic glow through an app on your smartphone.
