Brief update to my findings today.
LD is healthy and burning. I used a 9V battery and 5 ohms of resistance.
I ended up with 3.8V and 230ma for a whopping 874mW. It did slowly burn electrical tape. I ran it for about a minute. Nothing got very hot (ie the driver and LD well the housing at least).
Now if I did purchase a premade driver, which one would you recommend for 1.5W while using three 10440s? I ask because someone has recommended against the LM317 driver I am using...
