Actually, you have many options. Even though the search field is not ready yet in the database, I do have a Max lumen at 30 min mark in my spreadsheet for the most recent reviews. Normally, if the light can reach the >700 lumens after 30 min, you have good chances to reach it for 90 min or more with a 18650/21700 cell. I will try to paste the results here. My criterias are (1x18650 + 1x21700), >700 lumens after 30 min, form factor is limited to Angle light and Flashlights (no lantern, no headlamps, etc):
