LED Light Bulbs with Remote Controls and Aimed Lighting
Energy efficient light bulbs are cool already, but they are getting a whole lot cooler. The new LED EcoBulb by Seokjae Rhee raises the green bar with innovative features to save more energy.
For one, the bulb allows the user to only light the needed area with a small portion of the bulb’s surface aiming in the right direction (the bulb’s surface is divided into 6 parts). The brightness can also be adjusted, so you don’t have to have it on full blast all the time. The bulb also comes with a remote control, so when people are too lazy to get up to turn the light off (can’t imagine you’ve ever been in that situation) they can just grab the remote.
Cool bulbs. I’d love one of those.

I was in HomeDepot the other day checking out lights, they have a good selection of LED bulbs by Philips. The math is terrible though.
A 100W CFL is about $2 (4 for $8) and I got most of mine for 25c with the utility rebates a while back. They produce 1600 lumens for about 27W or 42VA.
A 100W incandescent sells for anywhere near 25c with no rebate and gives about 1600 lumens too and power is actually 100W and 100VA. Of course these will be gone in a year or two but are still useful for recessed spaces or bath overhead.
A 160 lumen LED is about $20 but might use 5W or 7VA est. That is 10x the cost and 10x dimmer before any rebates. Not sure if rebates should ever be granted for these, they are just too obscene.
The HomeDepot guy told me he had sold 1 or 2 that figures.
As a chip guy I pretty much fear these are not going to come down in cost fast enough since they are not based on Si but on the much more expensive Gallium Arsenide/Nitride/Phosphide III/V compounds. Right now silicon LEDs are not practical, there are several companies researching these devices that could use the much cheaper silicon manufacture process.
I see the DOE has an X prize, or L prize to get the next generation of lighting with at least a 50% improvement in lumens over CFLs or current LEDs and these need to be cheaper with better colors and solid state.
Personally I will hold out for a couple of years to see if any of OLED, Quantum dot LED, planar LED, or Si based LED come out.

This is a huge value add for LED lighting which will dramatically increase adoption. I am definitely gonna snag some of these when they come onto the market!

In the free pdf book “Sustainable Energy — without the hot air”, David Mackay throws some light on the subject of lighting in chapter 9. The rest is also good.

I purchased one of the Phillips LED bulbs from Home Depot. It was very difficult to fork over the $69. The light saves me 4 watts over a 15 watt Sylvania CFL. The light looks great, it is instantly on and full power vs the 15 watt. The light does not go in every direction and is very good for downlighting a desk. Even though the math doesn’t work, I still plan on putting these in hallways throughout my home. I piss money away on other more useless stuff so wtf. I have put in over 100 CFL bulbs throughtout my 6,000 sf home and my electric bill is $98 a month.
