My eyes:
In darkness-
320mW LCC red beam is dimmer than 150mW PHR blu, but dot is less than twice as bright.
In light-
Same red beam is brighter as well as dot, but not significantly.
At >100 yard distance, the red dot is pretty noticeable but the blu is washed out. In darkness at >100 yard distance the blu-ray dot is blurred and hardly noticeable. Red is clearly visible.
