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.
Many cheap alternative companies offer a 12V LED strip light in a 14.4W version. This is not enough voltage: a 12V LED power supply is not sufficient to give you full 100% brightness across a 5m length. All such high-brightness LED tapes should use a 24V LED driver.
For RGB LED tape
Our standard RGB 7.2W LED tape is available in 12V or 24V versions. (Compatible with either a 12V LED driver or 24V LED driver.)
The advantage of RGB 7.2W 12V LED lights are that their cut-points are positioned every 100mm. However these 12V LED lights are available in 5 metre reels only (because any length longer than about 6m will start to display dimmed lights due to voltage drop). By contrast, the advantage of RGB 7.2W 24V LED lights is that they are available in 10m lengths – without a voltage drop. This tape is ideal for larger projects or to minimise cabling.
The RGB 14.4W is supplied in a 24V LED strip to carry the current better for the higher power. Again these come in 5M reels as standard and voltage drop is noticeable after approx 6 meters.
