Are these good for flowering

They are 2700k

You are going to have to use a shit load of those. Maybe you should look into something like this http://www.urbansunshine.com/feliz-125-watt-2700k-compact-fluorescent. They are just big CFL's and they work way better than the small ones. They run like $35 for 125watt and like $15 for the plug. You dont need a ballast or anything but the bulb and a plug with a mogul socket. I have them running next to my 400watt HPS/MH.

Well I've been growing with a 23 watt clf and a 13w clf and a 4.5 watt led and its been going fine these are two 16 watt cfl spot lights

No way near enough light to flower with, unless you just want an 1/8,per plant.

Haha some people Ai , serious dude u won't a 600w hps all day for flower max your girls and look up super cropping

i agree not enough light, but ultimately its up to you
i would say defensive remarks like "well actually..ive been doing.." typically dont go over well it comes off as defensive, but also as that you really dont care about the answers we give you unless the answers are what you want to hear.

Well of u don't use bigger light don't be hoping for anymore than 50gram a plant dry haha if less

Woah, duder. You are gonna need more light than that. Could you survive on a spoonful of food a day? Yes, but you want be very healthy. Same with your plants.
