Isn't a watt a watt?
They're going on watt equivalencies. A 15 watt fluorescent is equivalent to a 60 watt bulb in light produced. Yes, you can safely upscale if the bulbs will fit.
Did this lamp (and the accompanying instructions) by any chance originate in China?
Nah, it came from Target.
Naw, it came from China by way of Target.
I also believe the new fangled CFL's put out more light per watt.
