You will need a bulb with a colour temp of around 4000 Deg Kelvin, but 500 or so either way won't make much difference to filtration.
Your main problem may be getting a bulb to fit because most LED bulbs especially speialist ones as they are usually fitted with a screw base. I use a 6500 degree LED to assess coour balance on RA4 prints and it is only available with a screw base.
You could do worse than contact the following and ask for their advice:-
