SUMMARY
To power 150 LEDs requiring 3.4V and 20mA using a 12V, 1A power supply, the optimal configuration is to connect three LEDs in series with a 100-ohm resistor for each group, resulting in 50 series connections. While using resistors is a straightforward solution, alternatives such as voltage doublers or triplers can increase the supply voltage, though they may not justify the complexity for minor resistor savings. Resistors are inexpensive and readily available, making them a practical choice for this application.
