LED Lamp Circuit Assistance

I’m putting together a small, home-based LED lamp and want to move from rough sketches to a fully working unit I can assemble on my bench. I have a general idea of the brightness and size I’m after, but I need practical guidance to turn it into a safe, reliable circuit.

Here is what I expect from our collaboration:
• Schematic design for the LED driver and supporting circuitry, optimised for efficiency and long component life.
• A clear bill of materials with part numbers that I can source locally or order online.
• Step-by-step assembly notes (photos or short video clips welcome) so I can build the prototype with confidence.
• Availability for brief check-ins while I’m soldering or testing, in case I hit a snag.

If you prefer KiCad, EasyEDA, Proteus, or a similar tool, that works for me—I mainly need files I can open and follow. Should issues arise during my build, I’m open to a quick troubleshoot session, but the core focus is design and assembly guidance.

Please let me know what experience you have with LED lighting circuits and how soon you could deliver the first schematic.
