One of the projects on my to do list is to create my own Neopixel/intelliblade string blade using 5mm (WS2811) round hat LEDs.
From my research it seems like they are prone to failure (in the naigon tutorial he instructs to make it in sections of 8 leds and test each section).

For anyone with experience, I wanted to ask if the supplier will make a difference. You can get them in packs of 5 leds for $3-$5 or you can get them from china for 100 for $20.
Is it worth the extra $$ not sourcing from china?

Also, they come in two varieties..clear and diffused. Any opinions on which are better to use?
Looking forward to the discussion
