I need to build a darkroom for our lab's experiment. We're using a 15 watt pump and will probably be around 3 watts coming out hitting the sample. Our primary wavelengths will be around 800nm and 400nm. We need to light the room housing the experiment with a light source that will not interfere with the results. Will I be able to simply use a fluorescence filter, say yellow or green, over an everyday white light, or is something else called for?
