Sounds like thats enough life for a night.
My experience with spotlights is this, ( I use Red Dykem ) I have a 200,000 Brinkman Varmint Special and once the Dykem was applied it is as bright as my newly purchased 1.5 million cp spotlight w/ Dykem.
Red filters may be the same (I remember comparing the two years ago), but I dont use them since they are more orange campared to the "blood red" color that the Dykem puts off.
With my 200,000 Varmint special in one hand and my 1.5 million in the other you cannot tell any difference in the intensity in the beam. My experience has shown me that filters of any type only allow so much light to pass through them.
Just my $.02.
