Not knowing the space you have for lighting,I'll go with a 'generic' answer. I'd use a standard 2-lamp,4 foot, flourescent fixture,[often called a Shop Light],and furnish it with 2 40watt lamps,one a "plant light",the other either a 'natural sunshine',or a 'daylight' lamp.
These lamps also come in 32 watt size,and can be used in the same fixture,if it is rated to accept either wattage type.
Home Depot or Lowe's both sell them.
The lamps can be hung within 6" of the top of the plant without any harm. Hope this helps.
PS: An incandescent lamp fixture can be used too,using a
60watt or 100watt "plant" bulb, but must be back at least
2 feet due to the heat it produces.These have a short life span compared to flourescent lamps.
