Upgrading the internals of a light?

I have an Eotech Integrated Forend light on my shotgun, it is 150 lumens, uses a CR123 battery and has an unknown (I haven't looked) bulb. I do know its not LED.
Is there a way to upgrade the light output on these? The new versions are supposed to be 250 lumens but Eotech says they don't offer a conversion.
I use this gun for night time hog depredation and home defense, and while the light output is sufficient for inside the home, it could stand to be brighter when in the field.
What can I change/upgrade on this light to make it brighter? I'm hoping I dont have to buy a whole new unit. Any help would be appreciated.

I did a little googling and I could not find one broken down. It looks like it might have p60 module in it though. Can you take it apart and show the pieces?
