Spiitz doesn’t mess around. Due diligence was exerted in researching and sourcing the highest quality material at the lowest possible price. We collaborated electronically over the weeks leading up to the build with Spiitz driving the design and me providing relevant links and technical advice.
Spiitz had everything we needed on hand except a few weatherproof electrical boxes and some odds and ends I brought along from my shop. He chose high density Tri-Chip High Output strip 300 LED elements per 5 meter length. Each LED element has three diodes, Red, Green, and Blue. 4 conductor ribbon wire is standard for installation.
Testing revealed a substantial impedance over 60 foot of 22 gauge ribbon wire (1.1 ohm) that resulted in a substantial difference in light output. Due to the construction and amp requirements of a 5 meter strip of 300 LED material a loop back to the controller is recommended every 5 meters.
One run of lighting needed to be an uninterrupted strip of 23 feet. To minimize and balance impedance we located the controller in the physical center of our lighting below the deck and used 18 gauge multiconductor wire from the controller to weatherproof boxes. We then used terminal blocks to make the connection to pairs of ribbon wires run up through the deck. We powered the 23 foot strip from each end to ensure even lighting,
No details were left unattended, every lead was tinned, every connection covered in heat shrink. On first power every LED lit simultaneously as we had expected. Lighting was perfectly even throughout.
The strips install into a tiny aluminum extrusion set into a dado channel made on my table saw. It would have been impossible to run these 16 foot 2 x 8 pressure treated rails through my little saw without Spiitz expertly tailing the long end of the lumber. Every step of the way Spiitz was there soaking up the process and putting his rather large collection of tools to use.
And without the hospitality extended by his Wife, I would have been sleeping under that deck. I hope you guys enjoyed the video. Sub Like Share
off grid inexpensive cabin, we decided to buy more solar.Harbour freight was having a sale on their solar panel kits,so we bought 2.They wete $109 each.
