I use 5k btu per 1k of lighting as a general rule of thumb when deciding on an a/c. That accounts for the light itself ,and the other room equipment
Okay, so if 5k BTu x 8 = 40k BTu
4 Tons = 12k BTu x 4 = 48k BTu
Got a safety margin built in twice, desirable to ensure I can deal with high RH in the space.
In other words, one Ton per two lights, with safety can be seen as a good rule of thumb.
