The top one is a CFL. "Warm Comfort" and 2500K suggest that's its in the Kelvin color range that you want for flowering. For Veg you want FULL spectrum 6,500K.

Top one yes you can use it but that is the flowering spectrum 2500k

You want some of the top ones but you need 6500k

The bottom one will be a waste of time.

To successfully grow 1 plant using the top bulbs you will need around 5 for your plant.

2 x 2500k
3 x 6500k

these will be good for veg

Then switch is around for flowering
3 x 2500k
2 x 6500k

But you will need this many to create enough usable light that your plant can use.

Do not take the equivalent wattages only the actual 24w x 5 = total wattage of 120w

interesting, im running 5 bulbs now and 1 plant. i have 1 27w(5500k), 2- 26w(6500k), 1 42w(2700K). im in veg now. would 4 26w(2700k) and 1-27w(5500k) be sufficient for flowering?
