@Coral Diver the BB lights are a bit deceptive in their claims.
The lumen ratings are theoretical max lumen outputs, not actual. They also do not use constant output drivers so they dim over the course of the burn. A good rule of thumb with their lights is to divide the lumens in half and use that to compare to some other lights. I.e. L&M actually gets lumens claimed, so will Light Monkey, UW Light Dude, Halcyon, etc. on their big can lights. All of the backup lights are around 70% of their claimed output except for L&M who actually measure their lumens.
