this might be kind of a weird or stupid question but my new 10 gallon planted tank needed some bulbs and i was pointed to using these bulbs

the picture is kinda small so heres some info from the box...
soft white bulb 2700K
light output of 825 lumens

there are two of them in the hood, they are supposed to replace 60 watt bulbs but only really use 13 watts of power to achieve that. does that men im running 2.6wpg or 12wpg? is there such thing as too much light?

has anyone else used these bulbs in there tanks?

thanks
