I have the L&M TAZ 1500. Most of my night rides I run at 1150 lumens which gives 2 hours of run time or for longer rides I'll run at 750 lumens for up to 3 hours. It is the best light of several I have. It is a little pricey but you can find them online for $220-240. I will also recommend L&M VIS 180 rear light which I use day and night.
