I'm looking at at a 65W triple tube CFL lithonia bulb and it's saying that the output is 300 lumens. If I go to a 13W CFL it's telling me that the light output is equal to a 60W incadescent(approx 600 lumens). Is this a misprint,wouldn't you figure that the 65WCFL would be 5X the lumens than the 13CFL?
