Since writing this review,thanks to another club member,I have come across the BIKERAY range.
These are external battery pack driven lights which will give you outstanding output and run time for an affordable price.
They have a range of spot or flood lights with various amperage and quality battery packs.
Three of us in our MTB section are using very successfully the RAY III 3 lead flood type which can be purchased from
two UK dealers. For more details check my review page:http://myweb.tiscali.co.uk/remember/cycling/80lights.htm
Thanks to Jean-Luc for this update
