Lighting has undergone dramatic changes in the last 20 years and is still continuing to evolve. When LEDs (Light Emitting Diodes) were first introduced, they were so expensive that they were out of reach for most people. Paying $40 for a light bulb seemed outrageous. But the cost of LEDs has dropped substantially and they are now available in a range of innovative, energy efficient products.


LEDs have jumped way ahead of the competition in terms of longevity with many of them having a rating of 50,000 hours. That’s about 10 times longer than CFLs. It is a new concept to think of the life of a light bulb in years. 50,000 hours equates to 17 years running the light for 8 hours a day.  You might have forgotten how to change a light bulb by the time you need to!

How many graduate students does it take to change a light bulb?

Only one, but it takes nine years!


LEDs use only 2-17 watts of electricity and 100% of that energy is used to produce light. They remain cool to the touch and do not produce any heat, which can make a difference if you are running an air conditioner. They are mercury-free, unlike CFLs, and are strong and solid, holding up well to jarring or bumping.

Toucan do it!


The most exciting innovation in LEDs is the introduction of a new breed of light bulb that not only allows you to change from warm to cool lighting but also lets you alter the actual color of the bulb, all from a mobile app. Whether you are in the mood for soft romantic lighting or something more theatrical, you can enjoy your own personal wireless lighting system at the mere tap of a screen.  You can set timers to produce different colors or types of lighting throughout the day. Wake up to a Serengeti sunrise or dine by candlelight with a simple swipe.


Products in this rapidly growing space include Philips Hue, Lümen by Tabü, Osram Lightify, GE Link, iLumi, Lifx and Cree. You no longer have to pick the right bulbs for each room. The Philips Hue app has four preset options for color temperature already built in: relax, reading, concentrate and energize. Choose “concentrate” while you are working in your home office during the day with a bright white temperature of 4500K, then switch to “relax” and a warm 2100K as you unwind at the end of the day and enjoy that well deserved glass of Chardonnay.

These latest LEDs are an investment but they are revolutionizing the way people interact with light and in a few years will probably become as common as lights on dimmers.
