When adding lighting data to an energy model it is crucial to include at least one correctly defined light type that covers the majority of the building.
As a minimum this is the lighting load W/M2 (luminous efficacy). For example, an LED ceiling panel may use 30 watts of power to produce a luminosity of 3000. This would give it an efficacy of 3000 / 30 = 100
Evidence to support this could be a lighting brochure similar to the one below.
