Are white LEDs going to beat CFL's in 10 years?
These days we gladly replace our traditional incandescent bulbs with these energy efficient lights (Compact Fluo Lights) which consume 3-4x less power for the same light
We realize how much energy we have wasted until now....
Now what about in 10 years? Is there yet another technology around the corner to consume even less electricity?
Latest white LED's produce a lot of lumens per electric Watt, will they ever make it into a bulb to consume even less than today's CFL? Will their color (white-blue) ever going to become a nice pleasant white?
yeah, and it'll happen in less than 10 years, i'm thinking.
LED's can be made to emit a light similar to the yellower daylight spectrum, though this adds to the cost. But LED's are quite cheap nowadays, available in any color imaginable, and very versatile (can be made to fit into things, unusualy installations, etc etc), as well as lasting damn near forever.
Ikea has a set of LED bulbs that can be used as mood lighting for a furniture line. They also have LED christmas lights, as well as head/turn/taillights for cars. It's only natural for them to be available as lightbulbs soon.
(the biggest problem with LED's by the way, isn't the color, it's light spread. Because of the design, LEDs tend to focus light into a narrower beam pattern, to be effective as lightbulbs, they'd have create a series of multiple, high wattage (1-3 watt) LEDs that would be installed in some form of diffuser casing, to spread the light out in a 360 sphere (for regular globe style lightbulbs). This would likely be rather expensive.
