In fact, standard T5 lamps are 12% to 18% more efficient than T8 lamps, averaging about 96–106 lumens per watt. High output T5 lamps generate nearly twice the light output of standard T5s, as well as T8, and T12 lamps.

In addition to the energy savings, it has

“Post Enron.” A year ago, who would have predicted that two-word phrase would ever exist, let alone occupy a prominent place in our collective vocabulary?

In this interview with two long-time green entrepreneurs, Danny Rubenstein and Janet DiGiovanna, Betsy Rosenberg explores the many ways that companies of all sizes can do well and do good at a time when going green has become a cost of entry to the marketplace.
