Use these 7 steps to get started on your Lighting Audit
A lighting audit is an important step in determining which lighting fixtures need replacing or updating. Conducting a lighting audit can help you implement cost-effective changes to benefit your business or facility, and give you a better handle on an expected project cost and return on investment. Plus, it will provide you a baseline of what is already in your facility, identifying potential installation conditions if any issues were to arise.
