Nice video. The runtime made me cringe a bit, at least we know colder outside temperatures do extend runtimes (I'd have expected that blue to die at indoor temperatures when ran that long).
Really interesting !!!!!!!!!!!!!!! The Green looks to be the tightest beam !!! And to my eye...the Red is the worst for astigmatic geometry...with the Blue also suffering from some spread !! But...Of course....THAT is the nature of all Multi Emitter LD's.....All three look beautiful.. Three high power multi emitter light engines THANK YOU for this posting !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
