OK,
Rather surprisingly, my little boost converter arrived from Hong Kong. It only took a couple of days.
I've unwrapped it and tested it in a variety of scenarios and I find the results rather interesting. For all four tests I used my bench PSU and my existing circuit and LEDs - the only change I've made (to test better) is set the PIC to control the LEDs in a simple way - 2 seconds all on, 2 seconds all off, repeatedly.
PSU directly to the circuit at 9v - the circuit drew 0.15a when it was set to white; although it wasn't white, it was kind of a bright pink.
PSU directly to the circuit at 12v - the circuit drew 0.55a when it was set to white.
Interposing the boost converter between PSU and circuit with the boost at 12v and the PSU at 9v - the circuit drew 1.01a - it was bright white.
Interposing the boost converter between PSU and circuit with the boost at 12v and the PSU at 12v - the circuit drew 0.73a - still bright white.
Interesting, I thought.
