the color rendition index(CRI) of incandescent light is ~100 which means they are one of the best light sources out there. however the color temperature of incandescent light is typically around 2700K which is very different from daylight(~5000K). since tungsten filaments has a melting temperature of 3695K, it is not practical to have incandescent light beyond 3000K. people who prefers daylight would typically get cool white fluorescent tubes(4000~5000K) or similar compact fluorescent bulbs. these fluorescent light typically has ill distributed spectrum far different from black body radiation of similar color temperature. thus they tend to have very poor color rendition index(70~75). there are ways to tweak the manufacturing of the fluorescent tubes/compact fluorescent bulbs to yield better color rendition index. these tweaked bulbs with high color rendition index(CRI>=90) are typically advertised as so-called "full spectrum" light. with these full spectrum light, you get colors as vivid as you would get with natural day light. but keep in mind that incandescent are by definition more " full spectrum" than these "full spectrum" light. it just doesn't have the preferred color temperature for many.

my point is incandescent light is "full spectrum". it is as "full spectrum" as one can get for its own color temperature.

Nevermind, just checked LZ's link. it's shitty CFLs, not incandescent bulbs.
