Luminaire Type Labels
Luminaire type labels will connect all of the luminaire symbols on the lighting plan to the specific pieces of equipment that they represent as defined by the luminaire schedule. Designers can use whatever “type” logic makes sense for the project. Often a two or three digit or alphanumeric code is employed. To keep luminaire selections clear, it is advisable to give a unique type to every variation of every piece of lighting equipment. Even if the variation is simply a lens, lamp type, or finish color, it should warrant a unique luminaire type.
Luminaire Manufacturer
This indicates who the product is made by and where specific questions regarding mounting, installation and electrification should be directed. Be sure to list the true manufacturer of the product, not a third party vendor who is supplying the luminaire.
Figure 25.1 The luminaire schedule lists the information a contractor needs to price and order all of the luminaires.
Catalog Number
The most important piece of information to accurately list is the product code that will be used to price and order the equipment. The catalog number is usually full of letters and numbers that indicate specific finishes, colors, mounting styles, and other options. Any small errors in catalog number will come back to cause larger problems during construction.
Lamp Specification
The schedule should include information on the quantity and type of lamp required for the luminaire. Sometimes it will be necessary to list a specific lamp product. Other times it will suffice to list the desired wattage and source type. It is always good practice to make sure that the lamp specification provides information about color-rendering index (CRI) and color temperature (CCT) to ensure that a suitable product is used.
Voltage
There are many voltages that service lighting projects. 120 volts is common line voltage for residences in the US, but it cannot be assumed. Larger commercial projects and projects that house heavy machinery often use 277 Volts as the primary voltage. The luminaires specified for a project must be designed to operate at the voltage that will be provided on the job. This is one of the first pieces of information that should be confirmed with the electrical engineer or contractor on the job. Luminaires that use low-voltage lamps typically require electricity delivered at 12 or 24 volts. These low voltages generally require that a transformer be integral to the luminaire or located nearby.
Mounting style
This piece of information will help an electrical contractor prepare the site for the luminaire well before it arrives. It can also head off any major conflicts with building conditions and space constraints.
Locations
This simple description of where the luminaire is actually used on the project
will save hours of looking for luminaire symbols on the lighting plan later.
Notes
This area is for any additional clarification information. The most common notes that show up on a luminaire schedule are related to ballasts and transformers that need to be provided, IC housing requirements, and wet-listing designations. This is the place to put information that is essential to the successful installation of the luminaire.
Remember that all of this information will serve the designer and the
electrical contractor on the job. The electrical contractor is a necessary ally on a lighting design job and efforts put towards clarifying the contractor’s job will benefit the design project as a whole.
