Question: I have very little experience with most modern commercial lighting, besides basic occupancy sensors, lighting in ceiling grids, photo cells, etc. So basically, none.I haven’t worked with lighting contactor panels, 0-10v dimming, ceiling mounted occupancy sensors, and some of the more complicated systems that I’m seeing on these smaller commercial jobs that I want to bid.I’m not a big “watch a YouTube video and now I’m an expert” type, I prefer to find and read the national standard textbooks, and then seek out professional training when I want to branch out.Does anyone have a personal favorite for getting onto speed on some of the new things coming out?One job I was looking at bidding, the lighting supplier added the startup from the manufacturer to the bid, and told me it would be a good idea if I hadn’t done it before to have them do the initialization.But I’m not even familiar enough with what part I would be doing and what part the supplier would be doing, so I passed on bidding it. But I’d like to be able to maybe branch out into this, since it appears to be the wave of the future.Thanks for any advice.

It's excellent that you recognize the importance of proper training and understanding before diving into more complex lighting systems. Here's a breakdown of resources and a recommended learning path for someone in your situation

1. Core Knowledge & Standards:
IES (Illuminating Engineering Society) Handbooks

This is your gold standard. The
IES Lighting Handbook is the single best comprehensive resource. It covers everything from lighting fundamentals, photometry, and design principles to specific application recommendations. Consider getting the latest edition. If you only get one thing, this is it.

National Electrical Code (NEC)

You already know this, but make sure you're up-to-date on the latest NEC requirements related to lighting, controls, and low-voltage systems. Article 410 (Luminaires, Lampholders, and Lamps) is critical.

ANSI Standards

Look for ANSI standards related to lighting controls and dimming protocols (e.g., ANSI C82.11 - Ballasts and Dimming). ANSI standards help ensure interoperability.


Manufacturer's Technical Documentation

This is CRUCIAL for the specific systems you'll be working with. Download spec sheets, installation manuals, and application guides for the brands you see frequently. Many manufacturers have extensive online resources.

2. Understanding Key Technologies



Lighting Control Panels



Contactor Panels

Learn how these are used to switch large banks of lights and how they interface with control systems. Understand the different types of contactors (mechanically held, electrically held) and their applications.

Relay Panels

Similar to contactor panels, but often used for smaller loads and individual circuits.


Networking & Communication

Understand the communication protocols used in lighting control systems (e.g., DALI, BACnet, Modbus). Learn how control panels connect to networks and how they are programmed.

0-10V Dimming



Basics

Understand how the 0-10V signal controls the light output. A 0V signal represents the lowest light level, and a 10V signal represents the highest.

Implementation

Learn how to wire 0-10V dimming systems, including the proper wiring techniques and troubleshooting methods.


Compatibility

Be aware of potential compatibility issues between dimmers and LED drivers/ballasts.

Sinking vs. Sourcing

A critical concept. You need to understand which type of 0-10V control your devices use.


DALI (Digital Addressable Lighting Interface)



Protocol

DALI is a digital communication protocol specifically designed for lighting control. It allows for individual addressing and control of luminaires.


Addressing

Learn how to address DALI devices and group them into zones.

Benefits

Understand the advantages of DALI over traditional analog dimming methods, such as two-way communication, diagnostics, and scene setting.


Occupancy Sensors



Types

Become familiar with different types of occupancy sensors (e.g., passive infrared (PIR), ultrasonic, dual technology).


Coverage

Understand how to determine the appropriate coverage area for different types of sensors.

Settings

Learn how to adjust sensor settings, such as time delay and sensitivity.


Placement

Understand the best placement for sensors to avoid false triggers and maximize effectiveness. Ceiling-mounted sensors are common, but wall-mounted and corner-mounted options also exist.

Daylight Harvesting



Photocells

Understand how photocells measure ambient light levels and adjust artificial lighting accordingly.

Algorithms

Learn about different daylight harvesting algorithms (e.g., open-loop, closed-loop) and their applications.


Integration

Understand how to integrate daylight harvesting systems with other lighting control systems.

3. Training Resources



IES (Illuminating Engineering Society)

The IES offers a wide range of courses and workshops on lighting design, control, and technology. These are often offered locally through IES sections. Look for courses specifically on lighting controls, LED technology, and smart lighting systems.


Manufacturer Training

Many lighting manufacturers offer training programs on their products and systems. These programs can be invaluable for learning the specifics of how their systems work and how to install and commission them. Reach out to the manufacturers whose products you are most likely to use.

Eaton Lighting Training Center

Eaton offers a comprehensive training program on lighting and controls.


Wattstopper Training

Legrand’s Wattstopper brand is a leader in lighting control. They offer online and in-person training.

Local Electrical Training Centers

Your local IBEW or similar electrical training organizations might offer courses on lighting control systems.

4. Practical Steps & Bidding Strategies



Start Small

Don't try to tackle a huge, complex project right away. Look for smaller jobs that involve some of the technologies you want to learn.

Partner Up

Consider partnering with an experienced electrical contractor who specializes in lighting controls for your first few projects. You can learn a lot by working alongside someone who has experience.


Focus on Commissioning

That's a crucial point. Understand the process of commissioning a lighting control system. This includes: Verifying proper installation. Addressing and configuring devices. Setting up schedules and scenes. Testing and troubleshooting the system. Documenting the system configuration.

Subcontract Commissioning

In the early stages, subcontracting the commissioning to the manufacturer's representative or a qualified third-party commissioning agent can be a good way to ensure the system is properly set up and to learn from the experts. This is likely what the supplier was recommending.

Ask the Supplier

Use your lighting supplier as a resource. Ask them questions about the system design, components, and installation requirements. They can often provide valuable insights and support.


Clearly Define Scope

When bidding on projects, clearly define your scope of work. Specify which tasks you will be responsible for and which tasks will be the responsibility of the manufacturer or a subcontractor. This avoids misunderstandings and potential conflicts.

Include Contingency

When bidding on a project that involves new technologies, include a contingency in your bid to cover any unexpected costs or challenges that may arise.


Software and Programming

Modern lighting control systems often require software for configuration and programming. Make sure you have access to the necessary software and understand how to use it. Manufacturer training will often cover this.

Regarding the Specific Job You Passed On

The lighting supplier's recommendation to have the manufacturer handle the startup/initialization is common, especially for complex networked systems. Here's a typical breakdown:

Your Responsibilities

Installing all the wiring according to the plans and specifications. Mounting the luminaires, sensors, and control panels. Connecting the power and low-voltage control wiring. Ensuring all devices are properly grounded. Basic troubleshooting of wiring issues.

Manufacturer/Commissioning Agent's Responsibilities

Powering up the system. Addressing and configuring the devices (luminaires, sensors, panels). Programming the system according to the design intent (schedules, scenes, etc.). Testing the system to ensure it is functioning correctly. Providing training to the end-user on how to operate the system.* Generating as-built documentation.

In summary
