Hi there!
I'm Pranav, from India.
You have basically given all the details required on the project description (which is one of the most well written, I have seen here on FL, thanks!), except for a few points that we can discuss on messages or Skype.
I am assembling a list of components and ideas right now, to make this proposal more exciting.
Till I get that done, you could have a look at my previous projects to understand how professional and fast I am on designing and prototyping electronics projects. I have a few years of knowledge, and well, your project falls right into my domain... :)
So I will update this when I'm done looking for great components for your project.
A few things I will need:
* Are there two lamps? One for low, the other for high? (I suggest one lamp, and PWM dimming it)
* PWM dimming? PWM is turning on and off a signal fast enough, for the human eye to perceive it as varying brightness (google it!) This will require Solid State Relays, or some other active, non-mechanical, switching device. General mechanical relays wear out over time, and aren't good for fast switching. They also make a bit of noise.
* Budget!!!! How much do you wanna spend on the RnD, and if its a manufacturable product, how much on the end product?
I will be supplying you with all files required for Design for Manufacturing. This includes my services for:
* Component selection
* Schematic design
* PCB Layout and routing
* Gerbers for PCB fab
* BoM, PnP, Component placement Dia
