The Electron Pico Super 2 front light is incredibly bright at the price and size, and as for battery, gives an impressive 117 hours in flashing mode. My only minor niggle was the sensitive switch.
It's a super bright, single watt design, identical to its equally potent rear sibling right down to clothing clip and resin mounting bracket, that seems strong, although the screws seemed likely to round off without taking care.
Electron's Micro 1W light is a commuter light with, as the name implies, a single 1W LED. This puts it at the being seen rather than the seeing by end of the bike light spectrum, even so it does provide a degree of road illumination, as our light data shows; enough for badly lit urban streets.
