When you’re buying LED strip lights, there’s a range of specifications – factors such as wattage, lumens per metre, and the type of SMD used in manufacture. But one of the most important items to consider is the voltage of your LED tape.
In this article, we’re going to look at the differences between 12-volt and 24-volt LED lights… and explore which choice is right for your project.
What voltage should I choose for my white LED tape lights?
If you’re installing LED lights with a low-end wattage, then 12V tapes are ideal. For example, our 4.8W and 9.6W white LED strip lights both draw 12V. This is enough to give you full brightness along an LED strip, up to a distance of almost 6 meters from your 12V LED power supply.
(Anything longer will lead to a voltage drop across the tape length, producing a noticeable dip in the brightness of your LEDs. If you intend to fit a strip of LED lights longer than 6m, you should install two strips, butted together and both wired back to your transformer in parallel.)
InStyle supply LED strips in standard 5-metre reels, which you can cut to the length you need. Or if you prefer, we can supply your 12V LED strip lights pre-cut. Cut-points for 12V 4.8W and 9.6W tape are located every 50mm.
Higher-wattage LED tapes, such as our 14.4W, 19.2W or 24W white strip lights, need the power of a 24V driver. This is because a higher voltage carries current more effectively – essential to produce full brightness across these LED tapes over lengths of approximately 6 metres.
Again, these higher-wattage tapes are supplied in standard 5m reels but we can supply them pre-cut to the nearest cut-point. Cut-points on 14.4W 24V LED lights are at 100mm intervals; the cut-points on 19.2W and 24W tapes are every 50mm.
