LimoStudio Digital Photography Video Continuous Softbox Lighting Light Kit with photo 105w bulb_AGG702

Would this be able to be used for creating videos? Also, is there anything else I'd need to purchase along with it?

what size is this umbrella?

How do you set up this product? I have the stand together but I do not know how to assemble the bulb into it. can someone help?

does this come with the white filter/cover shown in the first picture?
