    Has anyone had any problems with lights from Ray Wu's store? I have just got a delivery of pixel strings and they are not working. Previously bought strings work but put the new ones in and nothing.

    What do you mean by not working? What have you tried?

    Only issue I've had so far are some pigtails that were wired incorrectly, but that's no big deal as long as you test first!

    If they are new WS2811 pixels (or WS2812), and you have connected them to an existing controller to test, try seeing if there is new firmware for your controller and install it. There is suggestion that the refresh rate on new WS2811 ICs has changed: https://auschristmaslighting.com/threads/ws2812b-vs-ws2813-is-it-better.9561/#post-89267

    @QldKing(Brad) I wonder if this is a contributing factor to your issue??...
    @darylc is the firmware on current new F16V3 boards up to date for latest 2811 chips?

    I had an issue with my order from ScottsLed where he also used the new WS2811 chips that have a different refresh rate. After upgrading the firmware on my Sandevice controllers they are working fine, except when using with a 5 meter extension lead they don't work right so trying some different resistor networks to get them working with the 5 meter extension lead. Managed to get 8 different size resister networks spanned across 5 deliveries from Element14 hahaha now to test.

    The ic change is one thing and I am led to believe that the old ship is no longer available, so all of the new ones from all suppliers will be the new chip.
    The other thing to be mindful of, is that sometimes the wiring may be reversed. So if you are using the plugs that come with it and just plug into an existing set, then the data and ground wires may be back the front, i found this in my mega tree build.

    This year seem's like Ray has been rather busy... I have had more issues with his product this year, than previous years. Hopefully the current order i have been waiting on has no issues.

    Yes. No update required. Even the V2R doesn't need to update for the new chipset.

    No firmware changes were required for the Falcon boards, so even the very oldest firmwares will work with the latest 2811 chips.

    I had the same problem with rays ws2811s pixels with a firmware upgrade from sandevices all worked well, until i tried to run about 8 strings together and only half worked.After about 1 1/2 hour of trouble shooting i worked out that i was using a mixture of old and new pixels in the run. Changed out the old pixels and everything worked ok. Tried a few different combinations and found you cannot run old and new pixels in the same string.

    Thanks Guys. Great call. Ryan, thanks for the direction to the update file . I updated the firmware on my Sandevices controller and, voila, everything worked.
