Decorative Lighting

PTC mounts at the pole top; AMC uses a side-arm mounting configuration. They share a lantern appearance but are different mechanical products. Choose the existing pole/arm interface first, then compare the exact optic, CCT, output and side-panel configuration. A streetscape can use both styles, but the order and installation drawings must identify each rather than treating them as interchangeable mounting accessories.

PTC’s universal post-top fitter covers 2⅜–3-inch poles. AMC specifies the SAM side-arm configuration; its decorative scroll and non-scroll arms are separate accessories or can be provided by others. Check the arm’s attachment dimensions and load capacity against the AMC drawing. A matching visual style does not establish that an existing decorative arm has the correct attachment or structural capacity.

Yes. PTC and AMC publish separate performance data for no panels and their lens/panel options. AMC includes no-panel, textured polycarbonate, textured acrylic and a single-piece four-sided acrylic lens configuration. Panel choice changes output and optical behavior, so use the matching photometry in the layout and keep the panel code in the quotation. Do not approve a no-panel calculation and then order enclosed panels for appearance.

Do not apply one configuration’s approval to every lantern. PTC’s sheet identifies the no-side-panel configuration at 3000K or warmer for its DarkSky approval. Its panel, CCT and distribution choices still need the corresponding photometry. For AMC, use the exact approved configuration documentation rather than extending PTC’s statement to a different product. A decorative housing style alone says nothing about the approval scope.

Select the lantern, finish and panel style together with its optical distribution. PTC provides Type 2R/3R/5 choices; AMC has a broader roadway/area optic set. Both offer directional shielding, but current AMC shield notes exclude certain shields with T5. Calculate the actual sidewalks, roadway and adjacent windows with the chosen panel and shield; appearance and light coverage need to be resolved in the same submittal.

PTC PCR7-CS includes an output selector but leaves receptacle dimming wires unconnected; PCR7-CR is factory-wired for controls and omits the selector. AMC’s current sheet offers PCR7CR with standard 0–10V, plus a separate D4i/DALI configuration; its PS selector is not compatible with DALI. AMC’s cupola/node combination also needs factory coordination. A receptacle or decorative cupola does not establish the complete controller configuration.

The current AMC sheet lists CF coastal finish, IP66 optics and tool-free access to the hinged electrical/LED assembly with a kickstand. PTC’s sheet has its own construction and finish-test data, so do not copy an AMC salt-spray claim to PTC. Specify the actual finish and environmental exposure, and include access, cleaning and replacement parts in the maintenance plan for the installed lantern.

PTC is listed at five years in the current North America warranty; the current AMC specification also states a five-year limited luminaire warranty. Record model, mount, finish, panel, CCT, CRI, optic, output and controls by location, with matching IES and installation documents. Controller/service coverage is a separate scope. This prevents a visually consistent streetscape order from hiding materially different output or mounting configurations.
