Still confused on CFL Wattage?

So I read all the stickys, learned a ton about CFL’s but am still confused on which wattage to use for flowing. I know it needs to be 2700k but what wattage? I’m looking on a recommend site that has 200 different bulbs all 2700k but varying wattage from 3 Watt to 42 Watt also priced from $2/each to $15/each. Is a higher priced bulb really that much better then a cheaper one? What exactly are you paying extra for?

Would a 23 Watt, 2700K Warm White, 70 Lumens per Watt work for Flowering? My room is 36”x36”, am going to be flowing 4 plants.

Thanks!!!

A common rule of thumb is 100 Watts for the first plant and 50 for every other. So you would want about 10 of those. I have 12 cfl's flowering 3 plants currently. Hope this helps.
