Led Lighting For 72X30X27 Inch Planted Tank

[Bertiedootes]

Hi
 
I am looking to buy the above tank and wondered what amount of lighting I will need, and any recommended LED products. Possibly look to make my own with a kit? Wouldn't know where to start and best options for a 30 inch high tank.
 
Any advice welcome.
 
Thanks
