I've always wondered how the Outbound helmet light would compare to the Seca as far as beam pattern and output.
The Outbound marketing sounds like they have an inferior product that they are trying to drum up when they talk about not listing output and how "your eyes will adjust". They should list a Lux value (the amount of light measured at a given distance from the light source) as that actually has real-world use whereas lumens are more a theoretical or calculated output (and therefore a bit shit really).
I have a lux meter built into one of my multimeters (I'm an electrician) and have in the past measured the amount of light my various light systems put out in spot and peripheral positions. My old bar light was home made LED and was better than the bought ones I'd copied off!
*EDIT* I see outbound do actually list an approx output now of 900- 1000 lumens for the hangover lamp.
