So may be something like a Solux lamp (4700K incandescent) would do a

Yup or Gretag's SpectraLight Jr. light booth. SpectraLight uses tungsten
filtered halogen bulbs. Solux is a task lamp or track lighting set-up. The
SpectraLight Jr. booth excludes ambient light from the viewing area, does
not contaminate monitor screens with viewing light, and allows the intensity
to be calibrated to match your monitor's luminance level or ISO 3664:2000
standard.
