[EU] Green 10mW laser for continuous use?

[TVG]

Hello,
I am looking for a 10mW laser that can be used for around 10 minutes of continuous use.

Currently my design uses 12 laser pens (which the button taped down so it stays on) connected to a power source. These pens are from DX and they seem to be failing on me. I want to swap these with a more professional option.

Requirements:
3V
<350mA
10mW
'Continous' use (around 10 min)

Could someone suggest a seller? I live in the EU.

Thanks!

Are you trying to combine the 12 or trying to make a star pattern?

The 12 of them are individual and all connected to a DC power source. They do not form a pattern or something, they are all pointed at something different.
