Tricolor Dimmable Lamp Electronics -- 2

I’m building a line of premium desk lamps that pair resin shades with cement bases for the U.S. market, and I need rock-solid electronics behind them. Each lamp must let users switch between daylight, soft white, and warm white G9 LEDs, dim smoothly through a rotary dimmer, and run safely on 120 V AC. Every component has to be UL-certified and available off-the-shelf so I can source parts in the States within a week for pilot builds.

Here’s what I’m looking for you to deliver:
• A concise schematic (PDF or native ECAD file) that lays out the full circuit: 3-tone selector, rotary dimmer interface, on/off, and over-temperature protection.
• A bill of materials listing specific G9 bulbs, sockets, drivers, color-change boards, dimmer modules, and any thermal or EMI safeguards—with direct U.S. suppliers or equivalents.
• Wiring and assembly instructions that my small team can follow, including gauge, insulation, strain relief, and grounding notes to stay within UL best practices.
• A short troubleshooting brief covering flicker, audible buzz, excess heat, or inrush-current issues we might meet during bench tests.

Important Note: Once we procure the hardware and test it with the equipment provided by you, only then will we be able to end the project.

If you’ve designed consumer lighting (especially G9-based fixtures) and can point to past UL-listed work, that’s a bonus. I’m ready to move fast and will be assembling the first prototypes next week, so clarity and parts that actually ship inside the U.S. are critical.
