Analog LED Strip Calculator

Analog strips drive every LED from one signal, so there are no effects, no zones and no data line to worry about. What you get instead is light: more lumens per euro than any addressable strip, and white diodes commonly available at CRI 90+, which is why these are the strips to use when the LED run is the actual room lighting rather than decoration.

They also run hotter, draw more current, and cut in coarser zones than digital strips, so the wiring needs more thought rather than less. Enter your length below for the current draw, the injection plan and an aluminium profile to sink the heat into.

When to use Primary Lighting (Analog)

Primary use: Primary/general illumination (ceiling, walls) or basic accent lighting where uniform lighting is needed.

Analog strips offer consistent, broad illumination at a lower cost. Since all LEDs share the same control signal, it's not designed for dynamic effects but excels in providing uniform and bright light, which is ideal for primary lighting.

Additionally, analog strips often feature high-quality white diodes capable of achieving a Color Rendering Index (CRI) score of 90+, meaning they render colors more accurately and vividly, making them a great choice for spaces where natural and precise color representation is important.

  • Ceiling lighting (general illumination in living rooms, offices)
  • Wall lighting or coves
  • Accent lighting for simple, uniform effects

How the calculator works

  1. Select the purpose of the lightstrip. Choose whether you are lighting for ambience, for task and accent work, or as the primary light source for a room. The purpose determines whether you want digital RGB, digital RGBW or analog strips, and the calculator only offers strips suited to it.
  2. Enter the available length. Enter the length of the run you need, in metres or feet. The calculator works out how that maps onto the strip's cut zones, since a strip can only be cut at fixed intervals and the usable length is rounded down to the nearest cut point.
  3. Read the results and bill of materials. Each matching strip expands to show its power draw in watts and amps, the number of power injection points needed, and a full bill of materials: controller, power supply, wire gauge, aluminium diffuser and tools.
