There has different working voltages of LED lights, nowadays, LED strips are the most popular type of LED light driven by constant voltage LED driver, the general working voltage are 12V and 24V.
As for constant 24V and 12V LED light, the LED strip light driven by 24V power supply has longer permissible distances between light source than 12V LED light.
The difference of 24V LED light strip VS 12V one
- The cut size: 24V type is almost twice longer than the 12V type. Based on the same power, you can cut the size of 12V LED strip with every 50mm, however, for 24V led strip light, you should cut every 100mm. So, the cutting length of 24V LED strip is twice longer.
- The drop voltage: 24V LED strip performs better in drop voltage, which means the brightness from the very beginning to the end of the strip is almost the same.
In conclusion, 12V LED lights are ideal for lower wattage tapes, for example our 4.8W and 9.6W tapes both require a 12V LED power supply. This will give you full brightness along the LED strip, up to a length of approximately 6 meters from your 12V LED driver. (After 6m you will start to see a noticeable dip in brightness due to voltage drop. Beyond this length, you will require a second reel of 12V LED lights, to be wired back to the transformer in parallel.)
We supply our strips in standard 5 metre reels, as this is the optimum length. Or if you prefer, we can supply your 12V LED lights pre-cut to the lengths you need; cut-points for both 4.8W and 9.6W 12V LED lights are located every 50mm.
Any 14.4W or 19.2W LED tape needs to run at 24V. This is because the higher voltage will carry the current better, which is required to produce full brightness across the LED tape up to approx 6 metres. Again, these 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 every 100mm; the 19.2W tapes cut-points are every 50mm.
