its 42w equiv. to 150w and lets out 2700 lumens so was just wondering if that is the right bulb for flowering my plants?

and last question.. do lumens even matter? or are the Kelvins all that really matter?

THANKS TO ALL WHO REPLY!

No. Lumens can be thought of as how strong/bright the light is to the human eye.

K refers to kelvin which is a color band reading. What color is the light? 2700K would be a warm white (orangish hue) good for flowering stage. The higher K bulbs such as 6500K would be good for the vegatative stage and would be more blue in hue.

no daylights are called daylights or full spectrum. cool or warm white is 2700k it usually says 2700k on the back of the box...in small lettering u have to look closely and read all the small print cus most of the time when people buy bulbs they dont care what "k" it is lol
