Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

OK, well I'm new to this whole thing and I am planning on making a MXDL laser with DDL's driver. In his tutorial--in the materials section-- it gave a link to the MXDL and it was a 5 watt, instead of 3 watt.

-I'm wondering if I am able to use the 3 watt, and if so, is there any difference between the two and is there anything that I have to do different than the regular 5 watt mod?

Thanks.
