12v or 24v LED tape?

What is the difference between the 12v and 24v LED tape?

For white LED tape:

12v  is ideal for lower wattage LED tape such as 4.8w and 9.6w. This will give full brightness along the strip up to around 6m. Anything after that you will get a voltage drop. Standard LED tape will come in 5m reels as this is the optimum maximum length. 12v LED tape gives you cut points every 3 LED's. This is every 50mm for the 4.8w and 9.6w LED tape.
12v LED tape should be avoided in the 14.4w LED tape, this does not have enough voltage to give continues brightness throughout the 5m reel, you will start to see a voltage drop after around 3m meaning less brightness. 12v LED tape in 14.4w is non commercial grade.

24v LED tape is ideal for the 14.4w and 19.2w LED tape, this will give enough voltage to give 100% brightness along the 5m reel and can even stretch up to just over 6m before you notice a voltage drop. cut points will be every 6 LED's.

Warning: Avoid 12v 14.4w LED tape this should be 24v only


For RGB colourchanging LED tape:

12v  can be used for the 7.2w LED tape, this will give maximum reels of 5m and will give 100% brightness till the end of the strip. Avoid 12v RGB 14.4w LED tape as this is not enough voltage to give 100% along the full 5m reel, after around 3m you will start to get a voltage drop and therefore less brightness.

24v  in 7.2w LED tape comes in 10m reels. cut points every 6 LED's (200mm)
24v should also only be used in the 14.4w LED tape as this will give enough voltage to give 100% brightness along the 5m reel.

Summary of what voltage LED tape you should use for what wattage:

Whites -
4.8w LED tape     =    12v
9.6w LED tape     =    12v
14.4w LED tape   =    24v only
19.2w LED tape   =    24v only

RGB -
7.2w LED tape    =  12v / 24v  (24v is better as can run up to 10m lengths)
14.4w LED tape    =   24v only

Warning: Avoid 12v 14.4w LED tape this should be 24v only
