Why LEDs haven’t yet cut energy use for lighting

Marmax Products in County Durham recycles plastic to make outdoor furniture such as picnic tables. Last year, the firm finally made the switch from incandescent bulbs to LED lighting in its warehouse and offices. “We felt that, because of our product range, we were doing our bit,” says Dave Johnson, general manager. It was an energy reduction audit that flagged the possibility of moving to LED lighting. “You can always do more,” adds Mr Johnson.
