Exterior lighting power

Hello, We have a project where some luminaires have more power than what it is required by the mandatory provisions of exterior lighting power. However the actual power necessary to obtain the lumens needed for the project is below the power requirement. So we plan to lock the power of the luminaire during its installation so it will never exceed the mandatory requirement. We think of this approach because the exterior lighting designer cannot find a luminaire with the exact wattage needed. 1) Do you think this approach is acceptable? 2) How to show compliance during the design review as the technical documentation of the luminaires will show a non-compliant wattage? Does it seems acceptable if we include the requirements of blocking the power in the construction documents?
