The battery charger and lights plug into the same socket on the battery pack, so it's simple to handle the charge/use switchover. I've strapped the battery pack, using the velcro strap, to the handlebar stem, so there are no cables dangling over the frame.
The pack took barely an hour to charge (from out-of-the-box levels) and the light quality seems great. There are three light levels for each light: full-power, low-power and flashing. I think it's silly that there's a flashing option for a front light system, but never mind, The single button on each light is a simple way to toggle through these lighting modes.
Here is what CTC staff have to say about this lighting system:
You can easily pay twice as much for lighting like this, but there's nothing shoddy about the Electron system. Finned alloy housings keep the LEDs cool, lateral lenses provide side conspicuity, switches are positive and the battery connection - often a weakness in cheap lights - is secure.
Te battery can easily be strapped to the stem or any convenient part of the frame up to 1.5m away from the handlebar.
Sure there are brighter lights, but I don't think many people should need them. The spot alone seemed perfectly adequate for road use, should last all night if switched to low part of the time.
The only weakness I've experience with these lights - during two years of regular commuting - is with the power cable running from the battery unit to the lights. The symptom is that the lights flicker and cut out, as the frayed cable loses its electrical connection. There's no exterior sign of damage, but I managed to effect a repair as follows:
Don't attempt any of this unless you're competent at basic hardware and soldering techniques. Proceed at your own risk!
