    Hi I did a quick search and did not see anything (my wife would say I had a mans look) and was wonder if one can get WS2811 Flood lights I know there are DMX but I want to avoid the extra controller

    Do any of your pixel controllers have a DMX512 output?

    Richard I'm guessing you have a pixlite 4 or 16 controller as it seems you are limited to one pixel type. I think most of the other commonly available controllers handle multiple pixel types (but I have been wrong before). If you do have a pixlite then there are at least 2 dmx outputs on the controller (may be 4 I can't remember). If my understanding is right you can effectively put 510 channels through each of these outputs to run multiple flood lights etc daisy chained together. I know there is actually 512 channel in dmx but I'm assuming each light uses 3 channels, hence 510 useful channels.

    Like i13 said most controllers have a dmx output as well. Or do you already have these outputs in use.

    I have Pixlight 16's and Falcon Controllers, I know the Falcons have DMX outputs, can I connect Floodlight directly to the DMX output without the need of another controller card? If so How?

    Yes you can. You might just need to make an adaptor between the RJ45 sockets on the Falcon or PixLite 16 controllers and the XLR plug that is often wired to the floods. The DMX signal only uses 3 of the wires in the Cat5 cable. The exact wiring you need is in a combination of these two wiki articles
    http://auschristmaslighting.com/wiki/DMX_Adapter_Leads
    http://auschristmaslighting.com/wiki/Connector_Pinouts

    Termination is also recommended. The resistor shown is between the DMX+ and DMX- and I found seeing the diagram here helped me picture the wiring better.

    Remember when ordering floods that it is a good idea to ask the seller to set the DMX start addresses before sending them. This can be hard to change and it is particularly bad if all of your floods have the same start address.

    I have a several of PixLite 16 controllers, a Pixlite 4, and a several Falcon F16V2s. They all have DMX outputs. I use a Pixlite 16 to run these:

    I cut off the XLR connections and use standard 3-wire pigtails for better water proofing, and 3-wire Tees for easy water proof power injection.


    I have 8 of them permanently mounted as landscape lights and several more for seasonal use and as spares. I use a Beaglebone Black as my scheduler so that I do not have to tie up my home PC and network. I have them set to come on at dusk and go off at dawn.


    During the off season, I just have them come on as all white lights but during the season, I incorporate them into my show.


    Each one uses three DMX addresses and can be programmed by Ray before he sends them to you. Since I have some as spares, I need to be able to program the DMX addresses myself. In order to do that, you need one of these:

    pixel floods..
    Hmm interesting concept..
    A Basic RGB flood with a ws2811 pixel IC an a couple of mosfets should do the trick..
    Time for some work bench testing i think..
