Please tell me where can I get a lamp , preferably online, that is bright as high noon indoors?

I bought three lamps from WayFair and they are not good enough. I want a light that I can read from as natural sunlight . I bought two 100watt desk lamps and a 150watt floor lamp. I also have another lamp with white light and it is not bright enough. Do you suggest any online lamps or other light source that I can buy? preferably under $250.
