Kistheeze, when I said that NO bulbs don't even put out enough watts to be counted, I meant it in Euphoria's situation. Because 260 watts of PC + 80 watts of NO does not equal the same as 360 watts of PC, even though both add up to 360 watts (errr did I do my math wrong?) nvm that but the first one adds up to 340 not 360 watts.
It would be like I put a 9 watt PC ontop of my tank and add 200 more incandescent watts. This would add up to 209 watts, but it isn't nearly the same as 209 watts of PC.
