Eek! ****-colored 3000k light. Also, you'll have to isolate those
in the ceiling or they'll suck every ounce of heat out of your house
in four minutes flat.

More money, but it's a more pure art form for the shop. ?titter?

And wire nut 120V to the loose wires? That thing is ~4" long and 2"
diameter.

No, you pull the front bezel out and pop a donut in the hole to rim
the edge, pull your zip cord through that, and wirenut it inside the
can.


All I'm after is emergency lighting, and they will not suck out any
heat. I was planning on making a long, thin box to mount them down the
hallway, and some similar mounts for the rest of the house.

I went with inexpensive pullcord globe lamps. They were $4 each and
$4 delivery for all, so $28 for 6, delivered. Sucha deal! Pull-
switches cost another $4 each and the lamp place cut the holes and
installed them at that price, or I would have done it myself, though
my Whitney/Roper hand punch doesn't have a die that large. They had a
nice little desk-mounted DiAcro punch which worked well. The spots do
brighten the bottom of the globe a bit more, but the diffusion is
great, so it's hardly noticeable. I was pleased. It makes them
better for reading if you sit directly under them, with them mounted
on the ceiling. I mounted one surface-style, but will have to go into
the attic and drill holes/solder wiring for the rest, preferring that
over wire nuts for longevity. That'll probably happen in January, when
handyman work is gone for the season. I'm surprisingly busy right now
for the first time since I started the business.
http://tinyurl.com/lokpctl lamps I wanted point control on lighting
so I opted for the pull switches.


I may try some of the 48-LED panels in those. Have you seen them?
They stay pretty cool, too, and draw 135ma at 12v. I'm really
surprised that nobody has boxes or bezels for them yet. They're not
quite as bright as the 9W spots, but this is emergency lighting, after
all. Dim beats dark by 1000%, and bright draws too much energy.

The heatsink
is almost cold to the touch. It measures less than 6° F rise and has
been on for hours. It is 2" from the back of the flange, to the back of
the heat sink, so it won't take much space.

Nice! The MR-16 style LEDs I bought replace the old halogens and are
2" in diameter, too. Their heatsinks do rise in temp, but won't burn
you in the ranges I have: 3, 4, and 9W. The 9W flashlight I made has
an (so far) open bulb. I need to clean that up to protect it, but it's
sturdy so far. http://tinyurl.com/l75hr6y
Just have another of my 3c LED units starting to flash - on it's way
out in less than 4 months ---
