4 in 1 Epistar Chip 19.2 w/m vs 14.2 w/m - Which is correct?

Q: Why is it that I've seen 4-in-1 Epistar Chip LED Strips at 19.2 w/m (watts per meter), while yours offer 14.4 w/m? Which is correct?

A: 14.4 w/m is based on average readings for a 5-meter length of RGBW LED Strip. If we estimated power consumption, based on 100mm (or 10cm) sections for example, then we could say that the power consumption (per meter) will be around 36W, as there is almost no voltage drop. At Hi-Line, we try to indicate a true average power consumption and we believe that 14.4 w/m works better for calculating correct power supply requirements. Bear in mind that two different quality LED strips having the exact same power consumption will not have the same brightness levels, as one may be more efficient than another; meaning that higher efficiency LED strip lights will consume less energy (watts) and have much higher brightness.

It's always best to know exactly what you're purchasing, no matter where you purchase from; certain outlets may say they offer high w/m, such as 19.2, but this will likely have been calculated across unrealistically small sections of strip and therefore may not be indicative of runs at 5m and beyond.

Hi-Line always uses High-Efficiency LED strips and considers the efficiency of light carefully, as well as realistically. When it comes to most installations, there will always be voltage drop and therefore you can be sure that we have calculated for such an inevitability, with the utmost accuracy.
