Full daylight is bright. Unless you're very careful how you set things 
up, you are likely to just get washed out colors...remember that 
computer displays have a very limited range of brightness. If fully 
sun-lit white is 100% brightness, what's sun-lit + spark-lit white going 
to be? 100%.

Anyway, radiosity also isn't going to give you sharp shadows. It'd 
really only be good for giving an area with lots of sparks an overall 
glow.

Uh...I think your indentation scheme needs a little work.
Anyway, you've done everything necessary to have the spark emit light, 
now you just need surroundings suitable for showing the emitted light. 
Also note that because you have no absorption to your media, it will not 
show up in front of bright backgrounds...the limited dynamic range 
problem again.
