Thanks Per,
They had quite a big selection of headlamps downtowm and I could try them all, none seemed that great, except the really big ones, which are expensive. I then saw a Bric light in the bike shop for 300 SEKS, which was the brightest of the bike lights, although it's LED. I've bought one of those and will give it a go tomorrow. It doesn't seem to be water resistent though.
Thanks Per, helpful as always.
