The Foundry Edison

The squirrel-cage filament drawn to look like 1908.

Multiple parallel LED-on-glass strands shaped into the cylindrical squirrel-cage geometry that defined Edison's 1880s carbon-filament lamps. Clear or amber glass, 2200K candle-hour CCT, and a filament that renders the second-half-of-evening register without the soot of the original. For restaurant pendant arrays, industrial revival lofts, and heritage hotel lobbies where the lamp is the architectural statement.

WHERE THE FOUNDRY BELONGS

Three install registers. One lamp.

RESTAURANT · BARE-BULB PENDANT

The tubular lamp on its own cord.

Restaurant pendant arrays. Speakeasy and craft-cocktail bars. Coffee-shop ambient overheads. Clear glass shows the filament; 2200K CCT renders skin tones in the second-half-of-evening register without the soot of the original lamp.

INDUSTRIAL REVIVAL · LOFT & TAPROOM

The lamp that earns the building.

Converted warehouse lofts, craft taprooms, maker-space studios. The squirrel-cage filament is the architectural detail — the lamp is the reason to leave the bulb exposed. Amber glass deepens the industrial register.

HOSPITALITY · HERITAGE BUILDINGS

200 lamps. One historical reference.

Boutique hotels in pre-war buildings, restored grand hotels, restaurants in heritage interiors. Heritage binning kits ship 3-step MacAdam matched samples for the lobby chandelier where the period accuracy matters.

FILAMENT TECHNOLOGY · SQUIRREL-CAGE GEOMETRY

A filament drawn to look like 1908. Behavior tuned to 2026.

Multiple parallel LED-on-glass strands shaped into the cylindrical squirrel-cage geometry that defined Edison's 1880s carbon-filament lamps. The strands sit in clear or amber glass; the cage structure is visible at every install register. Operationally: 25,000-hour life, full TRIAC and ELV dimming, 70% energy reduction over the carbon-filament originals these lamps were built to evoke.

— PARALLEL CAGE

Six to eight LED strands arranged in a cylindrical pattern matching the original squirrel-cage carbon-filament dimensions. Visible at every viewing angle.

— COLOR REGISTER

2200K candle-hour CCT renders amber-warm without the sooty cast of older "warm white" LEDs. Intentional approximation of the candle-to-Edison transition register.

— HISTORICAL REFERENCE

Filament geometry documented against pre-1940 lamp catalogs and restoration architect references. ST19 envelope dimensions match originals to within 1mm.

— HERITAGE BINNING KIT

For the restoration that requires the right lamp, not just any lamp.

Heritage binning kits ship 50 lamps from the same production run with verified 3-step MacAdam consistency and matching squirrel-cage filament geometry. For restoration architects specifying 200+ lamps in a single heritage interior — the lobby chandelier, the corridor sconces, the bar pendants — where period accuracy and visual consistency across the entire space are non-negotiable.

ORDERABLE VARIANTS

Ten datasheet variants. Two envelopes (ST19 · ST21). Five filament suffixes.

All E26 medium-base. Amber and Clear glass options. Standard-warranty 3-year / 25,000-hour rated life per datasheet. JA8-2022-E and T20-compliant variants available where required.
