I was at my local Walgreens today and found these on clearance. The are the 3 outlet outdoor power spikes with a 6 foot cord for $3.89 seemed like a really good deal.
They also had spot light holders for $3 and some change. These are nice holders. they have a removable ring (3 screws) above the socket that makes it very easy to mount a baffle on your light. I used these same ones to build my light cans using a 1 gallon paint can.
