I've got a Trelock LS 950 from Rose last winter, it's pretty good. I generally run it on level 1 at this time of year and the battery lasts over 40 hours on a charge. It'll do 6 hours (I think, can't remember off the top of my head) on full whack which is enough to ride unlit streets by, wouldn't take it off road though.
The battery gauge is a proper digital count down, which I love, although it makes my other rechargable lights seem censored with their vague systems of lights and flashes.
Edit - This one https://www.rosebikes.co.uk/article/tre ... aid:470889
That's great service and they are great lights. Will they last? Dunno, but worth keeping IMO.
