If that is a high output t5 fixture it will. I think they have them at Home Depot. The high output bulbs are 54 watt each in the 4 foot length. I have one 4 bulb 4 foot fixture and one 2 bulb. I am keeping my clones going under the 2 bulb now. A bluer light is better for vegging. They label them with color temperature in degrees Kelvin. Mine are 10000 but anything ‘cool white’ should work for you(I think above 5000 is cool white).
