Hey guys I'm looking to install LED strips lights underneath the tread of our outdoor garden stairs. I have 5 rows of stairs and each row is 1.5wide. I will need to install 5x 1.5m led strip's under each tread. My question is what's the best way to connect these strips to a power supply, in series? Or run dedicated wires to each strip and connect multiple led strip's to one power supply? Is that even possible? 12v or 24v and I'd like to have a PIR as well. Thanks in advance for any solid advice to this complete novice!
In parallel. if you connect them in series, the last one in the string will be a lot dimmer than the first. It's up to you whether to use fat cables running from string to string, or separate thinner wires to each.
Get an appropriate LED supply for the number of strings you're using.
You can buy standalone PIR units. Connect your power supply to one of those.
