I use 3 flourescents around the opening of my spray booth, although the light is a little soft (diffused) it is good to work in, if i need a colour match i do that on my desk under the halogen light. the 3 lights and white booth eliminate shadows in the work area.
regarding the fire risk, are you talking about from heat (fluros burn much cooler than tungsten); sparking (this should not occur if the lights are fitted correctly, and would be more likely to occur in the exhaust fan); or wiring (once again should not be a worry if it is done correctly).
