LED replacements for home lighting

This is probably old news to you all (I've not been following very closely lately) but...

I'm assuming this will simply result in higher tech, low power LEDs clustered in cheap chinese fixtures running off of poorly made AC/DC power supplies that will kill the LED in a couple years anyhow.

Either that, or they'll cost a fortune when made correctly and mounted in good fixtures with decent drivers.

Need more info.....unless the entire package, including power supply and heat sinking is being tested for the MTF rates it's all pretty meaningless.

Under no circumstances should you buy Lights of America 120vac LED light bulbs. They are the showerhead multi 5mm types that I have only found at 1 of 3 local Walmarts for $6. Had 2 dead out of the package. Had 3 just stop working. Had 4 gradually lose brightness to about 50% in less than 6 months. A local hardware store had some really nice floodlight LED's, but were $160. So off the self LED lighting has a long way to go before they're inexpensive, bright and reliable.

McGizmo's house is all LED, but he did it all himself: 12V LED Lighting

The article was typically vague but alluded to a new manufacturing process, and that these lights were not yet available. Using Silicone instead of Saffire crystals, etc.

Impressive nice job!
Did he also make the metal core PCB strip ("Cree bar") himself, or can this be purchased somewhere?

Yeah....sorry we came off as kinda harsh - it wasn't directed at you.

The problem is...somebody could invent an LED that had 100 CRI, cost $.01 to make, had perfect 4000k color temp at an efficiency of 800Lm per watt, and was made from recycled baby diapers and absorbed CO2 from the air.

That theoretical 'wonder' LED would then find itself mounted to cheap chinese bulbs using low quality DC drivers and sold at Walmart for $19.99. 50% would then fail in the first 6 months.

The new tech sounds cool though. Too bad the only people that would use them would be the DIY crowd here, or for street lights {sigh}
