Hello there! I am Dharmesh, a Electronics and PCB Layout expert. I understand from your description that you are looking for someone with expertise in developing a specialized solar-powered circuit that is suitable for use with a single cell lithium battery. Specifically, you are looking for someone with experience in creating LED light circuits that require between 1-2W of power and have a 3.2V UV LED lamp with a 60mA current rating.
I believe I am the perfect person for this project! With over 10 years of experience in electronics and PCB layout, I have the knowledge necessary to create a fully functional LED circuit that provides the necessary wattage to the LED lamp while operating at 3.7V voltage rating. Additionally, my end product should continue to function until the battery BMS cutoff point (2.8V), automatically turn on/off when exposed to sunlight, include an on/off manual switch as well as an auto-on/off function, and work without issue on full brightness without needing any battery charging from the solar panel directly.
I would be delighted to assist you with developing your unique solar led light circuit! Please let me know if you would like me to discuss further or answer any additional questions
