If the 'average' intensity of direct sunlight on a warm summer day could be re-produced in a full spectrum light bulb, how many watts would that bulb be? I'm trying to find a bulb I can use to calibrate a photo sensor to sunlight intensity but my shop is on the base floor where there are no windows, and it's Seattle- no sunlight here.
I've searched google, all I get are light bulb ads. No useful info there.
