Option 2 – without extrusions
When installing exposed step-lights (without aluminium extrusions), the best approach is usually to stick your LED strip to the underside of the stair-tread’s overhang.
The LED light will then shine downward, creating a glow effect while hiding the light-source.
Wiring your LED step-lights
The wiring required to drive step-light LEDs is very similar to the wiring required for shelving and bookcase LEDs.
You can connect your power supply to the LED strips on each step either serially (end to end) or in parallel, as shown above.
