The case is now plastic rather than aluminium and it's an altogether smaller design, though the light is 400 lumens along with the green laser that projects the bicycle shape on to the road.
There are 4 modes Day Flash, Pulse, 100% solid, 50% solid and the laser on or off. The battery should last for 41 hours (according to Beryl).
No idea why the iPhone made the green laser look bluefish, but it's really green.
The original Laserlight cost £125, but the new Core is a much more wallet friendly £69.99 and much smaller so it can easily be taken off the bike and put in a rucksack or bag and not take a lot of space.
