What is a photometric plan?
A photometric plan (aka photometric analysis, photometric study) allows you to view the lighting level throughout the job-site in a 2D or 3D format. The goal is to achieve illumination specifications required by the city or by decision makers in order for your project to reach approval.
Photometric plans are extremely beneficial to all parties because it allows you to make changes to the lighting design before construction begins. This can save a lot of headaches down the road and creates a clear road map for your electrical contractors. For larger projects, a photometric analysis is a no-brainer and can save you thousands of dollars in extra labor.
A photometric study can also act as a reference for any legal issues that arise within your property line. These include rapes, kidnappings, assaults, accidents such as trips or falls, and protect you from any accusations claiming your property was not properly lit.

Photometric Plan Cost
A photometric plan (aka photometric analysis or photometric study) is usually free or low cost for large projects after the rebate provided by the distributor.
If the client only requires the photometric plan and is planning to get fixtures elsewhere, a lighting designer or architect will charge $1,200 to $20,000 depending on the complexity of the project.
Parking Lot Photometric
Parking lots are one of the most common photometric plan projects we receive. A large open area needs to have even lighting levels throughout and be above a certain brightness to be deemed compliant.
In order to pass city inspection, we need to achieve 1 fc (miami-dade county) and have 13:1 min:max ratio meaning the brightest point in this parking is at most 13 times brighter than the lowest point in the parking lot. This ensures ideal viewing conditions and safety during night hours. Parking lots are also ideal for crime, therefore, proper lighting is required to avoid expensive lawsuits.
Interior photometric plans for warehouses are essential to reducing energy costs and improving employee performance for any business. A warehouse with ineffective lighting can dramatically affect a business by decreasing inefficiency and lowering customer satisfaction.
Employees need proper lighting in an efficient workplace to properly identify aisles, bins, and products. A properly lit warehouse increases pick efficiency by providing clear pathfinding and identification. For large operations, even a slight 10% increase in pick efficiency can save millions of dollars annually. Additionally, if a photometric plan can reduce pick inaccuracy issues from 1% to 0.5%, that potentially saves millions of dollars in returns and unhappy customers.
Aside from employees, improper energy consumption can be costing your business thousands of dollars annually. Utilizing LED fixtures, our lighting designers can save you 50%-70% on your energy bills with one change. Additionally, we carry smart lighting controls that allow for motion sensors, daylight harvesting, and smart dimming options. For example,
- 100% brightness after detecting motion
- 10%-50% brightness during no motion
- automatic off after a set amount of minutes of inactivity
In your warehouse, not all aisles are in use all the time. Therefore, it is essential for any operation to have a proper lighting analysis performed. From our experience, smart lighting systems pay themselves off within 3 years of installation.
Many city codes do not allow for trespassing of light to neighboring property lines. In Miami-Dade County we cannot exceed 0.5 fc. To avoid getting fined by your city, our photometric studies include light trespass values. Illumination levels will be extended out to zero footcandles. Make sure that you understand your city code before performing any lighting renovation to make sure your project is in the clear.
Sports Lighting Photometric
Many stadiums require very specific light levels to ensure proper visibility. Proper lighting design highly affects player performance, spectator viewing distances, and prevents glare from affecting players and audiences. We also strive to create uniform lighting by overlapping light to avoid dark spots or hot spots.
All these game-changing factors cannot be nullified without a good lighting designer that understands the needs of a sports lighting arena. It is very important to understand pole positioning, fixture specifications, glare control, and uniformity strategies to create even playing fields.
