I'm making a lamp which uses lithium batteries in parallel to power the sensor module and the uC (an AtTiny85)

Would boosting the voltage (3.7 to 4.2 volts) to 10 or 11 volts and put LEDs in series of 3 be an efficient way to power the LEDs? It would be a pain in the butt to add individual resistors for each LED and have the brightness diminish with the voltage of the battery.

I would probably use a MC34063.
