You are shooting still images you don't need stronger light you need to learn your camera better. Use a longer shutter speed. Keep your camera still take a longer exposure image and the background will full up with light. If you need a more bright white buy a bulb with a higher k like 4100k that's the colour temperature of the light. Lower number means daylight a yellowish hue, while 4100k is more bright white. I would recommend learning about photo editing more and changing the white balance of the image in post. And adjusting the brightness and contrast for the look you want.
