We did a Pila GL3 passaround just recently (look in the passaround section). You'll find feedback there and under the reviews forum too. Excellent lights, with perfect beams. You can get'em from JSBurly's.
I alternate between GL3 and the G4 with LED emitter. Not bad at all.
Not labelled a wolfeyes, though I do wonder about things like quality control of Pila as compared to wolfeyes...
I know the Pila manuf has very high personal standards of expectation out of his products...does this automatically carry over to the wolfeyes brand due to the possibility of them coming from the same factory or am I missing something there....
