Default Modify NewWish driver

I have a few 5mW green laser pointers with a dead diode. My idea is change the diode to a 635nm red diode. The spec are :

SAMSUNG SLD63518262 5mW, 635nm Laser Diode
Output Power: 5.0mW typical,7.0mW maximum.
Wavelength: 637nm typical, 645nm maximum. RED
Operating Voltage: 2.2 Volts typical
Threshold Current: 30mA typical
Operating Current: 40mA typical
Monitor Current: 0.3mA typical.

I measured the current of the newwish driver and it is a whopping 250-280mA. Is there a cheap way to modify it to 30-40mA ?
Thank you for any idea's.

Default Re: Modify NewWish driver

Drivers that were meant for IR also were meant for +gnd LD's.

So even if you get the desired mA's you still have to isolate the LD from
the body of the host...
