Choosing an LED Strip: Voltage, Power per Metre and IP Rating
The LED strip is the most flexible solution there is, from a concealed light line to lighting inside furniture — but get three values wrong and the result disappoints: voltage, power per metre and IP rating. Our collection holds 63 products.
1. Voltage: 12V or 24V?
On short runs (2–3 metres) 12V is enough. On longer runs 24V is preferred: at the same power it draws less current, so the dimming seen towards the end of the run is reduced. Hose-type strips that run directly on 220V are preferred on long outdoor runs and need no separate power supply.
2. Power per Metre
The most common value in our catalogue is 14.4 W per metre. That is a class with a high chip density, capable of more than fill light. Lower-powered strips are enough for decorative accents; surfaces you actually work on, such as a worktop, need more power.
Driver sizing: work out the total load and add a 20% margin. For 5 metres × 14.4 W = 72 W, choose a supply of at least the 90 W class. You can identify a suitable model under LED modules, drivers and transformers.
3. IP Rating
- IP20: dry interiors — a concealed light recess, inside a cupboard, a ceiling line.
- IP65 and above: bathroom, under a kitchen worktop, facade, garden. The silicone coating protects the strip against moisture.
Light Colour
Four tones are evenly spread across our catalogue: 2700K and 3000K warm white (living spaces), 4000K neutral (kitchen, bathroom, office) and 6500K cool white (technical areas, stores). On RGB and colour-changing models the tone is set from the controller.
Cutting and Joining
Strips are cut at the cut points marked on them; cutting anywhere else leaves that segment dead. For joining, use solder or a suitable clip connector. Fitting the strip inside an aluminium LED profile both spreads the heat and softens the visible dotting.
Budget
Our 50 products with a published price run from 0.42 EUR to 478 EUR, with a median of 35 EUR. Single accessories sit at the lower end of the range and long runs on a reel at the upper end.
