My 445, (1x18650, not sure if its m140 or a140) comes on works good but after about 10 seconds its starts strobing, brightness never changes, any thoughts..

Usually means the battery is low, or cant hold a full charge.

Do a search, this topic has been discussed many times.

Here is how to check your batteries.

[Things]

Some batteries have internal protection circuitry that will try to shut off the load if the battery voltage, or current draw is too high. If your batteries are flat, the voltage may start high enough to power the laser, but after being on for a while, the voltage may dip too low, trigger the protection circuitry, and shut off the laser. When a load is disconnected from a battery, it's voltage will float up a bit higher, so it sometimes can get stuck in a loop like you're describing.
