Hi all,

I noticed some of the commonly used Chinese vendors are now offering for sale both Resistor and Regulated types of 12V WS2811 pixels and there is a little price difference between the different types.

Wired Watts has provided some information regarding this and some pictures to help you identify them.


I am just posting this as some people may be thinking of ordering pixels and it may be useful to know there is a difference in some of the 12V pixels which may be a reason for some price differences.

Also may be a idea to check what type you currently have if you are ordering more pixels for your layout.

I honestly don't know if it is a issue to mix and match the types but maybe be best practice to keep the string all the same type,

I would also specify which type you require when obtaining a quote from your preferred supplier etc just like specifying wire size and pixel spacing etc.

Now this just a little info post so please no responses like "My pixel supplier is best and I get the best price from vendor XYZ"

and please no replies "I use 5V pixels so it doesn't matter" :)

I use 5V pixels .... and 12V pixels. :)

As per chat, I'd say that the regulated type will give you a consistent brightness and colour over a range of voltage.

It's certainly something that should be discussed more here and at the minis.

What is the range of regulated pixels...? Could 12v regulated pixels work off 5v....? It all depends on the voltage regulators cutoff voltage. Might be something I could try with my 12v regulated pixels.
