12 volt LED lighting throughout house
TLGriff:
LED's are definitely the lighting of the future.
I'm in the process of converting the lighting in my home over to LED's and my latest victim was the energy sucking 500 watt halogen torchiere floor lamp in the living room. LED's typically have around a 50,000 hour lifetime as long as they stay cool, so the first order of business was to make a heat sink capable of keeping the beastly 100W LED comfortable. There are extruded heat sinks available, but I of course I wasn't able to find one that met my requirements so it was out to the shop. The stock was parted from a 6.50 piece of round aluminum and a mandrel pressed into one side to mount in the dividing head, then using a 3/32" x 5" slitting saw I proceeded to cut the 45 fins. This was one of those projects that didn't seemed pretty simple and straight forward at the start, but ended up taking around 3 hours to finish. The finished lamp puts out about 9000 lumens of light, which is similar the 500 watt halogen, but without the fire hazard, and it does it on 1/5 the power. The light of the "warm white" array had a slight green hue to it, so I added a magenta, or minus green gel filter to correct it. Now it looks just like the halogen and I think even puts out a bit more light. At least I don't have to worry about burning the house down.

Flippin 'eck, a 100W LED? I'm surprised it's not burning holes in the ceiling in that uplighter!
I worked out that the 48-element SMD panels I have are using 4W each... I have 20 of them so I guess I could almost match your single bulb!

Surprisingly, you can hold your hand a couple inches above the array without issue. Try that with a halogen and you'd be smelling bacon.
