hi guys, im a newbie to this hobby and currently i have a 15 gal. aquarium 24x12x12 LxWxH. Im planning HC/hairgrass/riccia/glosso as my plants and im planning to have a medium light since im only using 2 liters of soda bottle as my DIY CO2, ive read about the rules like wats per gallon and lumens, par etc. and still unsure with how many bulbs i should use. i currently have 2 of this DayLight bulbs

is this enough for a medium light in my 15 gal. tank? or is this still a considered low light? are all daylights bulb have a 6500k? thank you in advance for the help guys!
