Shared lighting energy budget
Estimate lighting energy across fixed and portable lights.
How it is calculated
Daily Wh = lamp count × watts per lamp × hours + portable-light Wh. Period Wh = daily Wh × days.
Assumptions & limits
Portable input is total energy for all portable lights. This does not assess adequate illumination, emergency egress or electrical installation. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.
Planning estimates only. Defaults are illustrative, not personalized recommendations. Do not use these calculations as medical, structural, electrical installation or other safety certification.
