In a proposed training class room with computer monitors, I plan to provide fluorescent tube light fittings centrally and a few emergency LED light fittings on sides. During projector operation, the lecturer can switch off the centrally arranged, group controlled fluorescent tube light fittings by two way switches and dim the light output from LED side lights. I plan LED lights because I think it is easier to dim. Also I think it is no problem mixing light from fluorescent tube lights and LED lights. Your input please.
