I know this has been discussed before, but I can't get a feel for the consensus. Are these 200mW modules on eBay ever anything like 200mW of green output? Has anyone tested them?

These are the things I mean:

200mW 532nm Green Laser Diode Module 3.7V-4.2V on eBay (end time 30-Mar-11 01:31:40 BST)

200mW 532nm 3.7V-4.2V Green Laser Diode Module on eBay (end time 08-Apr-11 01:19:31 BST)

200mW 532nm 3.7V-4.2V /Laser Diode Module/Green Laser on eBay (end time 20-Apr-11 10:59:17 BST)

Thanks!

I've never heard of pen module with glued-together crystals doing more than 150mW consistently,
but I might very well be wrong.

I can live with 150mW sold as 200mW. What I don't want is a 50mW sold as 200mW :yh:

I bought a 150mW and 100mW and they are great. The beams are very tight and well collimated. Power is as advertised on mine. Purchased from sellers laseryork and itemquickship in the USA.

Thank you, that's good to know. Sadly those guys only ship within the US (I'm in the UK).
