Q: I am interested in mounting a cylindrical LED billboards around a supermarket parking lot light post to display

A: Here are some key considerations for mounting cylindrical LED billboards around a supermarket parking lot light post in California:

1. Permits and regulations: Check with your local city or county planning department about any permits required and regulations related to outdoor advertising, signage size, brightness, etc. California has specific laws like the Outdoor Advertising Act that may apply.

2. Ownership and permission: Ensure you have permission from the property owner (the supermarket) to install the billboards on their light posts. Get this in writing.

3. Power supply: The billboards will need a power source. Work with an electrician to safely tap into the light post's power or find an alternative. Electrical work will likely require permits.

4. Mounting hardware: Use mounting brackets and hardware suitable for securely attaching the cylindrical billboards to the specific diameter and material of the light posts. The mounts must be strong enough to withstand wind and elements.

5. Height and visibility: Mount the billboards at a height that makes them clearly visible to parking lot traffic but does not interfere with the light disbursement from the post fixtures. Avoid blocking drivers' sightlines.

6. Image display: Ensure the billboard display technology is bright enough to be seen in daylight but not so bright that it causes a distraction at night. Program imagery that is clear at the viewing distance and speed of parking lot users.

7. Maintenance: Have a plan for who will maintain and service the billboards, replacing LEDs as needed. Temporary power shutoffs may be required for some maintenance.

8. Insurance and liability: Talk to your insurance provider about coverage needs relating to the billboards, such as property damage or personal injury liability if one were to fall.

Careful planning around legal, technical and logistical factors will help make your parking lot billboard project successful. Consult with local experts familiar with California-specific considerations.
