I recently moved to Sacramento and now live about half a mile from a airport and no longer want to use a 3.7W laser anywhere near a airport. Also selling my DL 589nm 30mW to have some money for other lasers in the future.
The blue laser is a NDB7A75 450nm with a 405-G-2 Glass Lens and a Xdriver set at 3Amps inside of a XML-T6 host also comes with 2 Efest 26650 batteries and a plastic sleeves if you want to use it with 2 18650s instead. The driver is not attached to the diode it's inside the host attached to a heatsink. So if you want to take the diode out and replace it with something else you can.
Both of them have less than 1 hour run time each. Here is a couple of pictures.

I'm asking $335 for the 589nm and $130 for the 450nm. Plus 7.15 for shipping in US. Outside will depend on shipping charges.
