I need a headlight system that will get me 800-1200 lumens for two hours. Or at least I think I do. I ride at night on the road with cars and some no streetlight areas. 16-25 mph. I am currently using 2 Zebralight sc600 II flashlights. SC600 Mk II L2 18650 XM-L2 Flashlight Cool White I run both of them on the H2 setting which should be around 670 lumens for each light. I love this set-up except I can't get more than 44 minutes. It was explained to me that when pushing cold air over these lights it forces the pid to run the lights brighter, but it reduces the amount of time they can run. If I put these same lights in a room and turn them on, I can get over two hours before they shut off. I carry extra batteries but I would rather not stop and switch them out. I was also running a Cygolite Expillion 700 with one Zebralight and it was a good blend of spot and spill, but I changed my handlebars and the mount no longer fits. For me I find that running the 2 Zebralight set-up allows me to see everything I want. I don't see at night as well as I used to and have recently started wearing glasses. I would like to take the lights off easily after the ride for charging and for riding on the weekends where the lights are just extra weight and not necessary. I do like to have redundancy in case a light fails and I like being able to tilt this light at drivers coming out of parking lots or turning from side streets. I'm open to all suggestions at this point. Maybe a multi battery (18650) flashlight, light system with a separate battery pack, or a strong USB powered light. I'm hoping to find a solution before it starts getting light again and I won't need any lights.
