Hello, I am hoping that you would be kind enough to help me with a question. I would like to use 4 LED's for a solar powered lamp that I am building. Would you be able to tell me exactly what kind of rechargeable batteries I would need for the 4 LEDs and if I need resistors? Is it necessary to have a pcb board for this project? And finally, maybe it's a longshot but does anyone know if there was a kit available for an outdoor solar lamp? Using the solar path lights just wouldn't provide enough light in the lamp. Thanks in advance.
