How to choose your lightbulb wisely? A study by Bob Tedeschi

Aug 12, 2011 A practical and exciting  consumer's guide to the galaxy of light bulbs has been published by Bob Tedeschi in the Seattle Times. The author highlighted the difficulties that buyers will be facing when trying to comply with the soon to be effective federal legislation to use more energy-efficient lights.  He notes, that beginning from January, any bulb that can generate the amount of light produced by a conventional 100-watt bulb, but do so with roughly 30 percent less energy, will be eligible for the market. The new law is gradual — in 2013, the rule will be extended to 75-watt bulbs, followed, in 2014, by 60- and 40-watt bulbs — but the point is that nothing is outlawed if it meets the new mandated efficiencies. The choice of the lighting solutions becomes more and more extensive and can really give a headache to someone who will be looking for the best efficiency/price/light warmth and distribution.

The author has consulted with the three leading experts (Konstantinos Papamichael, a director of the California Lighting Technology Center at the University of California in Davis; Russell Leslie, a founder of the Lighting Research Center at Rensselaer Polytechnic Institute, in Troy, N.Y.; and Craig A. Bernecker, director of the Lighting Education Institute, in Philadelphia) and devised his own 10 day testing strategy evaluating approximately 40 different light bulbs from incandescent to LED-based.

To our delight, despite relatively higher price tag, LED based light bulbs have won the author's heart for their outstanding lighting characteristics and long life, that  comes particularly handy if you are replacing lights in the hard to reach places.
