Full spectrum Bulb is the closest to the same light properties that is created from the sun.
Full spectrum light bulbs are made to try to imitate natural sunlight, and like sunlight, they also produce UV rays. Typically full spectrum bulbs have a Color Rendering Index (CRI) of 90 or above (100 is actual outdoor light) and a kelvin temperature of 5,000 or above. Full spectrum light is described as having a purple or bluish cast. Most light box companies using full spectrum light bulbs now block these UV rays through their diffuser screen, it's good to check to be sure.
Broad spectrum light boxes are described as being as close to full spectrum as you can get without the UV rays. Typically they have a CRI. of around 82 and a kelvin temperature of around 4200. Broad spectrum light bulbs are described as being a pure white light. Most light box companies use a broad spectrum light bulb so that there is no danger of UV rays.
It is also different the grow lamps for your plants.
