Those wattages are kind of useless.. Conservation of energy principle says you can't get more than 105W of light from a 105W bulb.. And plants don't see light the same way we do, so lumens aren't the most effective rating either.. PAR Watts relate directly to plant absorbtion, so read up on that, then overlay your bulbs spectrum and do the math if you really want a non BS number..
Bottom line is it really doesn't matter how many watts of whatever POS bulb they compare it to, its as useful as your plants say it is..
