Todd, More specific information re your product would allow a precise
answer, but in general:
Volume of Light: should be 100 Ft. Lamberts at the surface of the work
bench.  Measured with any convenient light measuring device (photographic
light meters are readily available with ft. lambert or foot-candle readout).  
Quality of light: subject to some debate, you may want to discuss with your
customer.  White light at a color temp. of 3000K is usually considered
optimum for visual (either unaided or via magnification) inspection and is
especially beneficial if you need to identify exposed basis metal or
discriminate between exposed copper and kovar/alloy-42.  Unless your
customer is NASA or some DOD agency they probably won't demand that color
temperature be defined and you can use whatever is available/convenient.
Color temp. is defined/specified by the bulb mfg.
Black light is a good way to check for the presence/absence of conformal
coating (given that it is doped to make it florescent).  Hope this Q/D
helps.  Jim Moffitt
