I purchased this for product photography but it is just far too weak to be of much use and the color is a bit too blue, there no way this bulb is 5500k, it's much cooler, but that can be fixed with correct white balance or in post I only mention it for the sake of bringing all issues to the table. If you are trying to diffuse the light with an umbrella forget it, it has an effective range of about 12", just enough to provide some back light in a portrait with the umbrella just out of shot, if you need/want to take photos of inanimate objects on a flat surface either you have to have it so close it's in the way of the camera or so far it's not effective enough.
