Definitely avoid fluorescent lights. Any new lights should be LED.

Workplace lights should have cool white or daylight white colour temperature, to keep the workers focused and alert. Never use warm white.

If you are lighting offices, then use task lights like floor lamps and desk lamps.

Avoid areas that either have too many shadows or are too bright.

Also avoid glare and especially flickering lights.

Good lighting can decrease errors by as much as 25% and reduce eye strain and headaches.
