Lights are the least of your worries. You need HPS for flowering. Flowering under MH will work but with shit quality imo. LED's may be good for your powerbill but from all reports 'shit' otherwise. There are a number of posts here regarding LED's. But the established growers amongst us will tell you 'Don't even bother'. If you want quality (and who doesn't) spend the money and go HPS. You will only get quality out if you put quality in.
Light is not the big vexed issue you seem it to be, but you will discover that as you progress. Every setup is different and as you go along you will need to make specific adjustments to best meet your needs, but don't get stuck at lights. Airflow can be more of a vexed issue than light but again you will discover that as you progress also. So can the level of salts in your fluids, thus the importance of an EC meter. Just concentrating on your lights can make you blind to the other important issues EC, pH and airflow. All these things need to be balanced and not just light.
