It depends on how strong your light is , my experience with cfl’s is limited but I had a 250 watt that I used for herbs and such in my window. Worked great for a couple of years but changed the bulb a couple of months ago with this fancy cfl/led that has a fan and all of the bulbs face downward. Generally, about 24” - 30” above top of seedlings should be a safe distance, you don’t want your seedlings to get too leggy. if they are getting too leggy move the light down.
Just dealt with this few days ago i had my first set of true leaves out so i put it right under cfl like 1inch and it burned the tips. Moved it like 3 inches away and its lovin it
Find the level at which you get upwards growth daily, not stretching but not like some who have nodes stacked so close. Youll get use to distances, in a perfect environment any stress is usually the light too close

I felt i could of had my t5's futher away still but notice how the first sets of leaves get really big quick when you dont oversaturate with light, see the next node seperating and looking uo for light.
Buy a second tent cheap beans and practice only seedlings till perfect, mainly you will find they dont need that much light
