Sorry, I have no idea which models I have checked. There is so much on offer, and at pretty scary prices too, that I decided it would be better to post my requirements here in the hope that I would get some recommendations.

I seldom cycle in the dark, however, living in Scotland the weather can be very overcast and dark during the winter months. And because we get a fair amount of rain, lights are needed in those conditions also. So, lights are not used often or in the dark and this is why I would prefer to limit what I spend on the items.

'Reasonably strong output' simply means adequate to cope with the conditions that I have described. I do not need them to light up a dark road, but do need them in order to be seen. Whatever that is in terms of lumens, etc will be open to debate and opinion, I would imagine?
