One word, Petzl.
They have a massive range and really do look after their customer with after care. You will definately find the type that best suits your needs as they have so many great ones.
I have had my Duo since my mountain rescue days back in the UK and it recently stopped working. Brought it into Mountain Equipment in the city, they sent it off and it came back all fully functioning and serviced all at no charge. This torch is well over 7 years old so bought the other side of the world. That is service!
