Particle system question

i have been trying to make a holiday scene and add animated snow. i have created a particle system and added movement to where it looks like the snow is falling–my only question is how i can make the snow look more solid–there is a halo-like “light” around each particle. am i going about this the right way or do i need to rethink my system. any comments?

You can make a snowflake object and parent it to the Emitter Mesh with Dupliverts to turn each particle from a Halo to an Object. Look in the Competitions section for a Python Shortcode contest that had scripts to make snow.
