Cateye Volt 400 USB Rechargeable Head Light - EL461RC - 400 Lumen  £31.99

I already own a Volt 300 with an extra battery and charger and was looking for an additional front light for my new bike as they are kept in two locations at the other end of the UK. I found the 300 to be the perfect front light:- very bright when required but with lots of modes when additional battery life is needed. In truth the additional battery is not needed as the battery life is excellent and charging time is OK. I have used the 400 and in truth though I can't see any real advantages over the 300 am totally satisfied. Only disadvantage is it is not a particularly lightweight unit (but that is the price you pay for a long battery life and a strong light).
