Cree 170 Lumen-Per-Watt Prototype

I read a study a couple of years ago that concluded that a lot of the efficiency gains in adopting new forms of lighting are negated by the increased use of lighting that those gains allow. In other words, more efficient lights = more lights, not less electricity use. You only have to look at the massive number of lighting fixtures (especially directional ones, such as spot bulbs) incorporated into new houses.

Sorry, but it’s utter crap… An LED bulb is typically 5-6 times more efficient than a halogen. You are not going to turn on 5-6 times as many of them. I am VERY familiar with lighting in modern homes. See my post: My adventures in LED home lighting

My house has over 300 bulbs (all LED now). I do leave on 4 of them (8 watts, dimmed down to around 3 watts) 24-7 as night lights and for maneuvering around when entering the hose. It is actually more efficient than putting them on timers. If anything, I have less bulbs on now than when I was using halogens.
