Default Estimated power of this module? (video)

Hello

I've found (on polish 'ebay') a blue module from laserworld 4000rgb, seller uploaded a video of testing this module.
He used some CRAZY voltage (8.8v and 2A) and the laser didnt fail. He claims that this is 1.5w module but at this barbaric voltage 1.5w blue would instantly fizzle, i think it may be well over 3w, could you watch and tell if my assumption was correct?

You can really know the mW of the laser just by looking at it. You would need a LPM to know the mW of the laser. BTW, a 1.5w laser dioderunning at 2A should not hit more than 2w

You can't assume anything. LPM required.

So how much should I offer him for a bare module like that without driver? 60$ would be fair?

Laserworld is well known for misquoting/inflating their power ratings. Expect at most HALF of what they quote.
