No you want CFLs, a normal light that is not around will not let the plants achieve photosynthesis, which usually leads to the downfall with plants. I would also lower thr light if you can. Not much useable light will reach the plants, meaning that there is almost no light hat they can use to photosynthesize, unless you have a TEK fixture, which that obviously isn't lol, you don't need the light that high.
So do make it a priority to get a 6500k bulb. I got a 15 watt CFL at my hardware store, it was the GE brand and it says 6500k on the side, note that when a bulb says natural day light it usually isn't 6500k and is lower on the spectrum.
