On an auction site, that will remain nameless to avoid the ire of the powers that be, there is a Malibu 12 volt 150 watt transformer. How many 3mm led's can be run on this?

I sure wish I could get to the make and take. WV is just too far away. Thanks for the fantastic information and references.

As far as I can tell the most economical wire to use is security system wire. 22/2 very cheap by the spool.

I am still looking for a power supplyl. It is obvious that the computer power supply is best but I want something that I can get. I do not have access to old power supplies. I Have found 12v 6amp converter for LCD monitors. They are only $17.00 including
shipping. They do have the little plug on the end. I wonder how I could get a female and make a distribution box for the landscape central delivery wire. I could then tap into the "trunk Line" with security wire (22/2) to the led spots. The power supplies look like the ones for laptop computers. I use cookie tins as a heat sink for my power supply when I use my lap top. I just set it on top and it difuses the heat very well.

Why doesn't anyone use the larger high output LED's.
I know DC cannot go great distances. Is this an issue for us using 100 feet of trunk line?
I am sure this is why the low voltage landscaping lights use AC.

Makes sense. If .24 cents will do it, why go with the more expensive. BTW last night I went to Lowes and compared prices useing the CPVC fittings, as used in the original article, compared to using the PVC with two bottle caps. The CPVC fittings were tiny and quickly reached $1.00 each. The pvc/bottle cap method makes a lot of sense. Thanks for shareing your inspiration.

Where did you get LED's with R for $.08 each. I can assume it was a group buy, but still sounds fantastic.

I think the pink looks more orchid and will look great for a graveyard. I think Green, blue and pink will give the best look. What do you think? The purple looks too dim.
