According to Paul Stoffregen’s Articles on December 6, 2017December 7, 2017, we know the APA102 LEDs strips have the problem at 24 MHz, usually after 150 to 250 LEDs.
But why? Here’s his attempt to investigate:One tempting explanation is signal quality problems due to horribly messy unterminated [...]
Pixel Protocol Overview: WS2814 This pixel protocol was designed by Newstar in China. WS2814 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to offer an RGBW design, making it one of the most [...]
hd107s 144leds led strip for special device
Comparison LED Strips: WS2812B, SK6812, APA102, HD107S
All LEDs are SMD5050 to compare (they also have 3535/2020/1515 size). There are RGB and RGBW variants for some of them (W of RGBW is used for an additional white LED 3000k/4000k/6000k CCT).
These LEDs fall into two categories:WS2812B, SK6812:3wires [...]
Many customer has doubts on the TM512AC and UCS512C4 DMX512 IC, and we have some customers complained the UCS512C4 DMX512 RGBW led strip which gamma curve of only 1.0 with which is a linear progression between brightness and DMX Value and with 8 bits of data [...]
Pixel Protocol Overview: WS2813 This pixel protocol was designed by Newstar in China. WS2813 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to offer both a redundant data line and a much higher [...]
Pixel Protocol Overview: WS2818 This pixel protocol was designed by Newstar in China. WS2818 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to support an output voltage of up to 24V, making it [...]

When you scan our web that you can find our 90% DMX512 led tapes are the UCS512 version, especially for the DMX512 RGBW LED tapes are the UCS512C4 series. But UCS512C4 version have an obviously shortcoming that is low bit which is only 8-bit gray scale [...]
Below is one real tested for 144leds HD107S and 144LEDs APA102. You can see obviously voltage drop for APA102 after 30leds, after 0.5m no signal and all leds turn red. for hd107s, only the end has a little voltage drop. also HD107S is brightness [...]
