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

Yeah but that voltage tho.

Maybe there are 2 diodes and beamsplitter cube inside?

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?

A link to the module would be nice

There is link to projector only, he is selling it as an addition, no photos. Projector is laserworld es 4000 rgb

No LPM, no way of knowing lol there are tons of members here (trusted) that will happily check the power for ya. Just pay shipping. That easy

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