Recently picked up a Black Diamond Cosmo headlamp through a massdrop (unimpressed with MD... prices are ho-hum at best) and was pretty exceited as the specs were reasonable, the weight was low AND it was rated IPX8... Well it arrived and it does appear to be a very nice lamp. Good fit and finish, attractive, bright and an interesting yet versitile UI. I just don't understand how it can be IPX8 rated, though. The battery compartment is completely unsealed. In fact, there is even a gap around the entire edge. I don't see any ridge or slot to house a gasket so unless this is a complete forgery (doubt it, packaging looked legit) then I doubt its a defect. Any thoughts? I did send an email to Black Diamond with pics and will be interested to see their reply as well.
And just to confirm, I did the cup of water test. It failed instantly. I watched the air bubble out as it filled up. I watched the water stream out as it drained when removed.
