Some fixtures are just a line on the schedule. Others set the tone of a whole building the moment the sun goes down. Exterior wall sconces sit squarely in the second group, and the family we keep coming back to for clean, modern facades is the Gardco GeoForm line from Signify.
GeoForm is a set of architectural LED wall sconces built around simple geometry and serious optical performance. The pieces stay understated by day and do real work at night, shaping pathways, entries, and facades with low glare and high efficiency. Here is a closer look at why it earns a spot on so many of our specs.
Why GeoForm Stands Out
Plenty of exterior sconces light a doorway. GeoForm was designed to do that while also looking intentional and carrying a consistent visual language across an entire project. A few things set it apart.
- A quiet daytime profile.
Compact, clean housings that read as architecture, not equipment, when the lights are off. - Serious nighttime optics.
Specialized distributions that balance low glare with strong pathway and facade performance. - One family, many shapes.
A shared design language across several forms, so a campus or mixed-use project can feel cohesive from the parking structure to the front entry.
Six Shapes, One Visual Language
GeoForm comes in six distinct geometric shapes, built around wedge, block, and cylinder forms in small and medium sizes. That range lets a designer match the fixture to the building rather than the other way around.
- Wedge for a crisp, directional look
- Block for a clean rectangular profile
- Cylinder for a soft, classic form
- Small and medium sizes across the family
Two Light Engines
The real flexibility is in the optics. GeoForm offers two different light engines, and choosing the right one is most of the spec.
Precision Plus optics
The efficiency choice. Precision Plus delivers Type 2, 3, and 4 distributions for pathway and area lighting, and these configurations are DLC Premium qualified. This is the engine for getting light on the ground efficiently.
Light Effects optics
The drama choice. Light Effects offers wall wash, spot, and pencil-beam distributions to accent a facade or a material. These can be inverted for a wet-location uplight, and a diffuse lens option covers over-door applications.
Performance and Efficacy
GeoForm is efficient enough to make the energy math easy. The wedge medium reaches up to 178 lumens per watt, with the rest of the family close behind, and lumen packages run from a few hundred lumens up to roughly 12,500 for the larger configurations.
- Up to 178 lumens per watt on the most efficient configurations
- Color temperatures of 3000K, 4000K, and 5000K
- CRI options of 70 or 80
- DLC Premium qualified on Precision Plus, and IDA Dark Sky Approved at 3000K and warmer
GeoForm at a Glance

Built for the Outdoors
A facade fixture only counts if it survives the facade. GeoForm is built for permanent exterior life.
- Low-copper die-cast aluminum housing, IP65 rated, with an IP66 light engine
- IK08 impact resistance
- Rated for ambient temperatures from -40 to 40 C
- A durable powder-coat finish tested to at least 1000 hours of salt spray
- Standard colors of bronze, black, white, dark gray, and medium gray, with custom on request
- A service tag with a QR code for lifecycle support
Controls and Energy
GeoForm fits neatly into a controlled lighting scheme, which is exactly what specifiers want on a modern exterior. Control options include 0-10V dimming, a field-adjustable wattage selector, motion response, and dual-circuit control, plus wireless Interact Pro outdoor for networked control and deeper energy savings. An emergency battery backup option is available for path-of-egress illumination.
FOR SPECIFIERS
Thinking about GeoForm for a facade or entry?
Roth Lighting can pull samples, help configure the right shape and optics, and support the spec across Southern Nevada and Northern Nevada.
The challenge:
A mixed-use exterior needed clean, consistent sconces that would meet energy code without looking like utility hardware.
The collaboration:
Roth Lighting helped match the right GeoForm shapes and optics to the entries, facade, and pathways, and specified the controls alongside them.
The solution:
One fixture family carried a single visual language across the site, with dark-sky-friendly, DLC-qualified performance and dimming built in.
Where GeoForm Fits on a Spec
GeoForm is at home anywhere a project needs clean exterior lighting with a consistent look.
- Building entries and over-door lighting
- Facade accent and grazing
- Pathways, courtyards, and site walls
- Campuses, mixed-use, retail, and hospitality exteriors
Conclusion
GeoForm is the kind of fixture that makes a specifier’s life easier: one family, six shapes, two optical engines, strong efficacy, dark-sky options, and controls that drop into a modern scheme. It looks quiet by day and does real work at night, which is exactly what a facade needs.
