I got this led strip some time ago: WS2811 RGB LED Strip Light Addressable Digital Tube DC5V 30LED M White Black US | eBay
Putting it to use it found it very difficult to get a warm white light out of it. Regardless of how i tweaked the balance between red, green and blue it never got to a really nice color. Looking at the output through a grating i found the colors to be very narrow band.
Is there a way to tell which led strips will have that issue? I have some other adressable led strips that seem to use much more broadband leds. They are totally different though, running of 5 volts instead of 12 and adressing each led individually instead of in clumps of 3.
The first strip is very good for producing strong primary colors obviously, i wonder if that is intentional. The listing really doesn't mention it specifically, but it almost looks like these leds were designed for tv backlights rather than general purpose. They are cheap and pretty bright though, so some people might really like them as long as it's not for general lighting.
