Dude! I've never had my very own zombie thread! Woo hoo!
BTW, I was so disappointed with the results, I sold that house and moved to Oregon. I just put in 18 recessed lights and they are all compact halogen (35 watt). I'm mainly over CFL, although I am waiting with baited breath for the technology/price curve to level on LEDs. Almost did it, but at $30-40 a light, that would have been an L-lens sitting in the ceiling of my kitchen... :O
BTW, I'm not really over CFL. Half my house is CFL. |

| An interesting follow-up: Phillips has won the L-Prize and 2012 could see a <10 watt LED that can produce 60-watts of light for <$18. Very interesting. |

Personally I only find these things interesting once the life cycle of the units has been established... otherwise one can be looking at very expensive lighting.

Fluorescent light at home just seems peculiar. |
Fluorescent lights in the garage without a cold weather ballast is a no no n the garage for me since I could die of old age before they turn on in the winter months.
We do have fluorescent lights in the kitchen (which no one has yet managed to guess are fluorescent, and I have had the same fluorescent bulbs in the night table lamps for several years now and have never had a problem with them... and no they do not look peculiar.
Considering that LED light up the insides of submarines and a bevy of other operational areas, I will definitely consider those, but only if the price is right.

They don't dim at all, do they? |
nope, on or off. |
and this is my biggest issue.... most of the main floor was done year ago as dozens of recessed light cans with the large bulbs... all on dimmer controls. The other places I do the CF although the life on some of them is parthetic and outside in winter they are a waste of time. |

There are special ones that dim, but they are ridiculously expensive and hard to find.
Edit: Wow, 4 year old zombie thread.

I believe I read that this particular light was tested for 18 months. At a maximum that would be 18x30x24=13,000 hours. But you raise a reasonable point.
Someone resurrected this thread a few weeks ago, but I saw the piece on Google news so I thought I'd pass it on for those who cared. I'm interested in LED lighting when it becomes slightly less expensive.
Here you go:
In June 2010, the next stage of evaluation began: long-term lumen maintenance testing. The 200 samples were sent to Pacific Northwest National Laboratory (PNNL) to be tested in a new high-temperature testing apparatus specifically designed for the L Prize competition and built with assistance from Orb Optronix. The test bed is maintaining 45°C to simulate actual operating conditions and will operate for a minimum of 6,000 hours. As of January 2011, more than 5,000 hours of testing had elapsed, and long-term testing is expected to be completed in Spring 2011.
