For severe coastal, high-humidity, or urban pollution environments, heavy-gauge solid brass and architectural bronze are vastly superior to cast aluminum or powder-coated steel. Cast aluminum relies entirely on an exterior paint film; once that paint suffers microscopic scratches or UV degradation, moisture and oxygen cause sub-film filiform oxidation, leading to blistering, flaking, and ultimate structural failure.

Solid brass contains no iron, meaning it naturally forms a passivating oxide layer (patina) when exposed to salt air and rain. This patina protects the underlying metal, ensuring that a post top lantern installed near ocean environments remains structurally sound for decades without rusting or deteriorating.

Standard commercial post top tenons typically measure 3 inches in outer diameter (OD) by 3 inches in vertical height, though 2-3/8 inch OD tenons (common in residential posts) and 4 inch OD tenons (common in municipal retrofits) are also widely used. At Brass Light Gallery, our post collars and pier mount bases are custom-machined or cast to fit your precise post top diameter.

Every post top collar features internal heavy-duty stainless steel set-screws that thread firmly into the tenon shaft, securing the luminaire against extreme wind loads (EPA tested for 90+ mph winds) and mechanical vibration without stripping.

Yes. We engineer fully shielded Dark-Sky compliant options featuring solid brass top hoods, downward-facing LED array modules, and internal cut-off reflectors that achieve a U0 rating (zero uplight in BUG classification). These configurations comply with International Dark-Sky Association (IDA) guidelines and strict municipal zoning ordinances while directing full lumen output onto walkways and driveways.

Our commercial luminaires utilize industrial-grade, field-replaceable LED modules paired with premium constant-current drivers rated for 50,000 to 100,000 hours of operation (L70 benchmark). Unlike mass-market integrated fixtures that require discarding the entire luminaire when a driver fails, all electrical components inside our heavy brass housings are fully accessible via drop-down base plates or removable roof caps, permitting quick on-site maintenance.

Specifiers can select from heavy hand-blown clear seeded glass, ripple glass, frosted white acrylic, translucent opal glass, and hand-leaded art glass panels. For public parks or high-vandalism environments, high-impact UV-stabilized clear or frosted polycarbonate lenses are available. Optical distributions can also be customized with internal louvers or reflectors to achieve Type II, Type III, or Type V light distribution patterns.

Yes. We supply fixtures wired for standard 120V residential circuits as well as 208V, 240V, and 277V commercial line voltages. Drivers support 0-10V dimming, ELV/TRIAC dimming, and DALI protocols. We also offer internal emergency battery backup ballasts (90-minute operation during power outages) and integrated 10kV surge protection devices upon request.

Because every fixture is built to order in our Milwaukee workshop, standard production lead times range from 4 to 8 weeks depending on batch volume and custom finish requirements. We maintain a dedicated Designer & Trade Program providing tiered volume discounts, complimentary finish chips, CAD/REVIT BIM models, photometrics (.IES files), and dedicated project manager support for architects and specifiers.
