FSL, Inc.

Our Approach

At FSL, our philosophy is simple: create illuminated experiences that are as functional as they are beautiful. We combine decades of expertise in lighting with principles of spatial harmony and purposeful design to enhance every environment we touch.

Backlighting

Our specialty is backlighting. It’s where artistry meets innovation. This niche grew organically from our passion for bringing light to vertical surfaces—blending the technical elegance of lighting design with Feng Shui-inspired principles that emphasize balance, flow, and energy. The result? Spaces that feel not only well-lit, but alive.

Whether we’re backlighting printed graphics, architectural panels, or unique materials, our solutions are tailored to highlight form and elevate function—transforming ordinary surfaces into luminous design features.

Signage & Branding

Illuminated signage is more than a name on a wall—it’s a statement.

At FSL, we craft signage and branding elements that capture attention, communicate identity, and align seamlessly with your vision. From glowing channel letters to sleek, edge-lit panels, our illuminated branding solutions are built to be bold, durable, and undeniably distinctive.

We specialize in:

  • Custom illuminated logos
  • Edge-lit and face-lit letters
  • Branded lightboxes and feature walls
  • Architectural signage integrations


Whether you’re launching a flagship location or enhancing a brand experience, our team ensures that your message shines—literally and figuratively. Every sign is not just a marker, but a memorable beacon of your brand.

CUSTOM LIGHTING

Sometimes, only a custom fixture will do. For those special projects where uniqueness is non-negotiable, we collaborate closely with designers, architects, and visionaries to bring signature decorative fixtures to life.

Whether it’s a sculptural pendant, an oversized wall feature, or an integrated lighting element that doubles as art, our custom pieces are designed to inspire—and built to last. With in-house fabrication capabilities and a passion for detail, we turn bold ideas into brilliant realities.
