LED Lights Are Here

Finally, LED lights are becoming affordable - and more and more common.  We bought our first LED bulbs a couple months ago at Home Depot.  Out of curiosity, I had stopped in to see if they were carrying them yet.  I didn't see any and asked the first HD employee I saw.

"Sold out," he said, "should get more in Friday."

I looked at the one empty slot on the shelves - amidst hundreds of options for different bulbs of all types, shapes and sizes.  "That's a good sign," I thought to myself.

I went back the next weekend and picked up a few bulbs that fit these weird candelabra fixtures we have in our new rental.  They're not super cheap - about $14 for a pack of two.  But they use about 90% less energy than the old incandescent bulbs, so they'll pay for themselves over time.  And when I see the coal plant burning less than a mile from our house, and know that we just took demand down a notch, that's priceless.

The light quality is great.  Here are the old bulbs:

And the new LEDs:

As most people know by now, Compact Florescent Lights (CFLs) are also big energy savers compared to the old fashioned bulbs - using on the order of 75% less energy.  But their mercury content has always been a concern.  On balance, they're worth it - they require burning less coal, which spews mercury into the air and water - and they can be recycled.  Your local Dept. of Public Works should have a mechanism for safely collecting old CFLs and Waste Management has mail-in recycling kits.

But now that LEDs are so accessible, it's time to go to the next level.  Be a market-leading consumer and show demand for them, which will help bring the prices down even more, even faster, helping them become the norm - and helping society make a big step towards the dramatic reductions in energy demand we need to make in the next couple of years.

Stay going.

Hi Georges -
I ran across your blog today. Your comments regarding LED and CFL are right on. As a leading residential and commercial retailer on the web is seeing an acceleration in the quality of LED products not to mention growing interest across nearly all of our customer segments.
