世論 What Japan Thinks

With LED lights providing a better performance and eliminating the slight warming-up problem in some fluorescent lights, this survey from iShare looked at issues surrounding these LED light bulbs.

Demographics

Between the 28th of April and the 7th or May 2010 535 members of the CLUB BBQ free email forwarding service completed a private internet-based questionnaire. 55.7% of the sample were male, 30.8% in their twenties, 32.1% in their thirties, and 37.0% in their forties.

Many of the bulbs in my flat are already flourescent, in particular the heavy usage ones are already upgraded, so given the current electricity and bulb costs, replacement takes over four years to pay off. Even the most-used incandescent bulb still has a one-year pay-off cycle – hmm, now I think about it, I should replace that one!
