Rube Goldberg has nothing on me 
When I wired our house 30+ years ago I neglected to properly allow for lighting the back yard. There is a wall washer and spot but because of the angles of the house and the extension out of the deck most of the back has very poor lighting.
I have been using up to 48v dc lines to feed my camera system in the woods with 12v reducing devices at the cameras / lights. It allows for using smaller wires because of the lower current draw on the 48v side. I drew up a plan to used 12-24 volt 50w led floods mounted on the face board of our deck, 10 feet off the ground, which is about 100 linear feet.
The plan is to have several 12v motion sensing devices placed along the length of the deck along with a number (to be determined - right now it looks like 5) of the 50w led floods.
When any one of the motion sensors is actuated it sends a 12 volt signal to the trigger line on an adjustable delay on break card. The card pulls in a 12 volt 20amp rated relay that sends ~20v out to the floodlights.
In addition I have a wifi card installed in the box that when activated will also trigger the delay card. I can then control the lights from my phone or computer.
The total delay is the on time of the triggering device (motion sensor or wifi card) + the delay I set on the card (.1 sec to 9999 minutes). When the basic system is in there will be several switches install on the deck so the lights can be switched on even though there is no motion in the yard.
It's a fun project. With the weather being crappy the last couple of days I have the box 99% done, just waiting for an ammeter to put on cover. I hope to start the deck wiring / mounting of the lights today.
The temp power supply in the rear is actually supplying 18.98v not 98. Must have been camera flicker.
