If you use indoor film with an outdoor filter the background will be blue. This is true for color video as well. You should check your video camera's manual and find out the procedure for setting the white balance. Since Kelvin temperature changes by varying the voltage to the lamp it is critical that you keep the voltage at the rated maximum when doing photography and video. If you have to much light you should use a neutral density filter, do not turn down the light.
Light sources come in three basic types incandescent, arc and fluorescent.
I mean the type of lamp in your lab ceiling not a lamp that triggers a fluorescent effect. Fluorescent lamps are used with stereo microscopes. The fluorescent tube is in a circle and built into a module that attaches to the front of the stereo. This produces a shadow free illumination at a very low cost. However fluorescent lamps can't be dimmed so what you see is what you get.
