    Lighting store controller

    Okay, I am looking for some recommendations on a request from a customer. Here is what I know...

    1. All lighting will be 120v
    It is a home building store that is about to start selling light fixtures.
    2. The owner wants the capability of controlling each light fixture independently.
    3. I am building the system to accommodate approximately 500 fixtures.
    4. He would ideally like to be able to have his sales people be able to control the switching from an iPad or wall mount controller. Ideally an iPad.

    I do not need to know about figuring the power requirements. I am looking for recommendations on controllers or systems with such a capability. Maybe someone has installed a similar system and knows a specific brand to accommodate this. I know I can call different lighting reps, but before I get to that point I am looking for some recommendations.

    Thanks for your help!

    I once wired a house for an Electrical Eng. he had me at that time which was years and years ago
    take a door bell wire from his computer location to all the controlled lights.

    It was a very costly system he made all his own programs.

    You really consult a specialist for that control.

    I would bet the customer has no idea what the cost will be
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.

    A PLC with an HMI could easily accomplish this; it is simple on-off with the possibility of some combinational logic. The PLC would drive a relay that would control each fixture. The PLC can be programmed to prevent too many light fixtures on a given circuit from being switched on and overloading the circuit. Many HMI's have a mobile app that can be used for remote control.

    This would be a large control cabinet. It will not be cheap. Does he understand what running 500 circuits worth of field wiring will cost him?

    Another thought:
    With this many circuits needing control, it's reasonable to look at a theatrical-style lighting control system, and distributed dimming, instead of running everything back to a large central control rack.

    Event Systems DIM-12 dimmer would be a perfect fit for this application. They're 12-channel; 20A 120VAC input, and each channel is capable of up to 5A output. Note that they have a 40W (0.33A) minimum load, to prevent flicker.

    I used one on a show for Broadway a few months ago. It was easy to set up, wire, and use.



    You'd need a DMX capable controller to operate the dimmer packs; the world is your oyster there. The City Theatrical DMXcat is a good place to start looking. It connects via Bluetooth, and gives you one universe (512 channels) of control. I tested one of these a week ago, and I was impressed with the app's ease of use.

    ElectricMatt:

    Try the following search string in Google:

    addressable light switch

    I think you would want to find an addressable device (dimmer-switch) that is locatable at or near the load to be controlled, and only requires two power wires.

    Realistic control could be by a power line carrier signal (think X10, but X10 is possibly inadequate and may have other problems ), a digital two wire bus system (this adds a low voltage bus that goes from one location to another), or a radio frequency digital control (adds no wires).

    The customer has NO idea what the cost will be. I asked for a ballpark budget, and he is clueless. I do nothing but t & m work for him, as this job will be, and normally once I have a good idea I tell him and he accepts or shoots it down.

    Awesome, thanks for the recommendation. I am waiting for their rep to give me a call back. Thanks!

    That right there should tell you not to put a lot of time into this.

    He is going to bring this lighting into the store in some capacity, he pays for design time, and I will be the one to install it regardless of how basic or complex it may become. If it were anyone else I would agree with you 100%, but I lose nothing for doing it. Therefore, I will get all the answers I can from those with more experience in this area and present those options. Thank you for the feedback though, I do appreciate it! ( not sarcastic if it sounds that way)
