Come on, just because others use them doesn't mean they should, or that you should
That is unless you don't give a crap about your health should one break, or the environment should you ignore the fact that the law says they need to be disposed of via hazardous waste
Now to your question
5000-6500K is fine for veg, but it is good to combine with ~ 40% warm white (~3000K) for better root development
for flower you want 2400-3000K, with 2400-2700 during later stages
Your option is led globes and/or tubes
