Adjusting the strength of the point_spotlight?

How do I adjust the strength of a point_spotlight entity?
Btw, are there any other ways of making light that blinds the player if he looks directly at it?

I need the light to make a players screen brighten up realistic if he looks directly into a light panel.

FX Amount? 255 is the strongest. Spotlight width should handle the size for a frontal view.

Consider an env_lightglow. It's the entity used for the blinding effect at the end of a tunnel.
