Is anyone else using these Samnet addressable fairy lights from China? They are low cost, as little as $17 for 20m strands. And low power, a standard USB phone charger is enough to power a 20m strand and 10m can be powered with AA batteries. And you don’t need diffusers as they are built in. They co…

Yep. Those are WS2812B lights and they are definitely nice. But the lights I was asking about cost 1/2 to 1/3 as much as WS2812s. How many meters did you use for the tree?

12 strings - 5m (50 pixels) each

One review claims to have used them with WLED.

How’s about to publish the details of your nice work ? :smiley:

Oh, they definitely work with WLED. It could have been my review you were looking at. I was just wondering if other WLED users are using them. And in particular, if anyone figured out a cool use for the fixed addresses.

Nice! How hard was it getting it over the tree in one piece without tangling?

I tested these out today to see how much power they draw. A 100 light string on full bright white draws just under 1.5 Amps. You can’t see the difference running side by side with a WS2812B string. How the heck did they pull this off?

Anyway you can show how you cut the wires and connected to WLED? Have these on order to play around with and would love to see your hookup! Thanks :slight_smile:

Sure, I’ll do that. Also, I noticed in WLED yesterday that the setting for WS2815 was just 0.013A per pixel. That’s a 12v light, but similar draw.
