| Progress on LED lighting |
| 2005-07-25 |
| LED lighting has the potential of drastically reducing electricity consumption (most lighting on cell phones is already done via LED) while reducing several classes of electrical accidents. Lighting consumes over 25% of US electricity, most of it via incandescent bulbs. A typical 60w incandescent will produce about 700 lumens. A compact florescent of about 15w will also produce 700 lumens but they are expensive and fragile. It seems if it will be possible to get 700 lumens out of a 3w LED. The company announcement below discusses a product that would have some niche applications. Full disclosure - I own stock in this company. DURHAM, N.C., July 25 -- Cree, Inc., a market leader in LED solid-state lighting components, today announced that its new white 3-watt XLamp(TM) 7090 high power LED, with maximum luminous flux of more than 90 lumens, has been selected to power Cyberlux Corporation's powerful new RelyOn(TM) portable work and emergency light. |

| #5 It sounds wonderful, albeit a bit "early user" for me. I'll keep an eye out in my local shops, and replace my current bulbs (about 50/50 incandescents and compact fluorescents) as they become available. I have to admit, not having to climb a ladder every few months to replace those stupid candle tips in the entry chandelier will be a pleasure! And Mr. Wife will be shocked and pleased when I reduce one of our major budget items... just in time to spend the money on the daughters' university tuitions ;-D |

| #4 mojo I think those luminaires use the previous generation of CREE products. The company hopes to at least triple the current efficiency (bada bum bumg). |

| #3 almost all brakelights, street signals are converting to LED on replacement - more directed light, less energy usage. A good deal all around |

| #2 PS19 with E27 or medium base that screws right into your current household socket. This is LED bulbs has 19 white LEDs with a clear polycarbonate lens for better light output - better clarity to view with, to see colors and objects clearly. Its performance clearly out paces the previous 18 LED model. Rated for 50,000 hours/17 years of white light at 8 hours per day. $21.50 per http://www.theledlight.com/120-VAC-LEDbulbs.html |

| #1 yeah, but it's only guaranteed for 60 hours. Apparently, it's for emergency use only. Don't retire yet. |
