This whole project only took about 1 1/2 days to complete. The first day to install the wiring and flexible LED lights, and the second to connect the controllers and go over the strips with clear silicon for extra protection. If you have any questions, please don't hesitate to ask! Enjoy :-)
Step 1: Draw Schematics
Draw a rough sketch of your deck including measurements. Decide where you want to put the lighting, making particular note of:
~electrical source (where you can get the power from)- this doesn't have to be outside- you can have the LED controllers/power supply in an attic or basement out of the weather and hidden and just run the low voltage wires out to the strips.
~Where you can run the low voltage wire so that it is not noticeable (for example under an overhang/lip of the deck).
~Where and how you want to control the lights from (wall switch, remote, DMX, or timer).
~ How bright you think you want the strips (this can help size the wire, controllers and power supplies).
After making the rough sketch, you must:
1. Decide how many feet of flexible LED strip you need. Also, decide which sections you want connected together and which ones you want to be able to control separately (for color or brightness).
2. The best way to run the wiring. In most cases you should plan on running a maximum of 2 rolls end-to-end per 22-4 supply wire- if you stick to this recommendation, you will be able to have long runs (up to 50') of the wire without having to worry about voltage drop.
Some final things to consider:
~ The more home runs (low voltage wire from the strips back to the controller), the better- as this will provide less voltage drop (power loss) and more options as far as control (if you ever want to add or change anything).
~ If you have a large area you can have several home run locations and either run a larger wire back to the controller or put an amplifier and power supply there to boost the power and signal.
~ If you are looking to run the strips at reduced brightness (dim level- an example would be for under stair treads or outlining your house, you can run several (4-6) rolls together on one controller and power supply. However, you must then keep the lights at this dim level (for example 35% of brightness) or your power supply will be overloaded and could blink or stop working.
~ Group the wires from each independent section together (each section which you would like to have individual control of), so that they can be connected to separate controllers/amps.
~ For large installations, make note of how many feet of flex strip are on each wire so you can correctly size the amplifier needed.
