Incandescent Bulbs Return to the Cutting Edge
- RiderOfGiraffes 17y agoEarlier in the article they said that a 70 watt bulb is now giving off the same amount of light as an older 100 watt bulb. They said it was 30% more efficient. Later in the article they say: > David Cunningham ... [has] develop[ed] a reflective coating and fixture design that he believes could make incandescents 100 percent more efficient. 100% more efficient? Zero power input? Me must really be giving 110% to acheive results like that.
