There are multiple ways to model lighting in OpenStudio. The type of lighting (LED, T5, CFL, MH, etc) doesn't really matter to OpenStudio and EnergyPlus.
You can specify individual lamp types, and then place the lamps individually within each room, using multipliers where appropriate. Use this if you have shop drawings which show which lamp types and how many in each room.
You could also specify a lighting power density, and apply it to a space. You would use this if you don't know specific lamps, and only know a target LPD.
You could also specify a lighting power per person in the space.
You can also control how the lamps are implemented: how much of the lighting energy is heat vs how much is light, as well as how much heat from lighting goes into the return air plenum.
