Premium storefronts, lobby signs, hospitality spaces, franchise rollouts, corporate interiors, retail environments, and branded commercial projects requiring both face and halo light.
Trimless Dual-lit Channel Letters
Seamless front illumination with a refined rear halo.
Trimless Dual-lit Channel Letters combine a clean, borderless illuminated face with controlled rear halo lighting. Three internal LED configurations allow the build to be matched to the artwork, letter depth, service access, and required lighting output.

Production Notes
Letter Style
Trimless Dual-lit Channel Letters
Direct face illumination with rear halo lighting.
Internal Systems
Dual-Array, Center-Spine, or Rear-Carrier
Selected after artwork, depth, output, and service review.
Face
Trimless translucent illuminated face
Face construction and graphics are confirmed around brightness and finished appearance.
Rear Halo
Controlled wall illumination
Wall color, texture, reflectivity, offset, and LED layout affect the finished halo.
Returns
Aluminum or 304 stainless steel
Selected around structure, weight, environment, finish, and fabrication requirements.
Return Depth
Per shared depth-to-stroke matrix
The selected return depth must be paired with the corresponding approved stroke-width range shown in Size & Depth.
Wall Offset
Project-specific standoff
Coordinated with halo spread, wall surface, mounting hardware, and installation access.
LED Color
3500K-6500K white or RGBW
Front and rear channels can be coordinated or separately specified when compatible.
Electrical
Project-specific power and control
Power supplies, controllers, circuits, wire exits, and service access are reviewed before fabrication.
Application
Interior or exterior
Exterior projects require project-specific sealing, drainage, wiring protection, and finish review.
3 / Size & Depth
Shared depth-to-stroke standard for all three systems.
Dual-Array, Center-Spine, and Rear-Carrier Trimless Dual-lit Channel Letters use the same dimensional relationship. Select the return depth first, then confirm that the approved artwork provides the corresponding stroke width.
Critical Planning Rule
Return depth and stroke width are paired requirements.
Both dimensions must remain within the same approved matrix row.
Shared Sizing Matrix
Return depth to stroke width
Applies to Dual-Array, Center-Spine, and Rear-Carrier Trimless Dual-lit Channel Letters.
Return Depth
Required Stroke Width Range
1-1/4" ≤ depth ≤ 2"
3/8" ≤ stroke ≤ 3/4"
1.57" ≤ depth ≤ 3.15"
3/4" ≤ stroke ≤ 2.36"
2.36" ≤ depth ≤ 4"
2.36" ≤ stroke ≤ 3.15"
3.15" ≤ depth ≤ 5.9"
3.15" ≤ stroke ≤ 4.7"
Applies To
Dual-Array, Center-Spine, and Rear-Carrier systems
Artwork Geometry
Stroke width is verified
Narrow strokes, tight corners, and small counters can limit the available return depth, internal carrier placement, and LED spacing.
Internal System
Selected after dimensional review
The shared matrix establishes the allowable proportions. The internal LED configuration is then selected around geometry, output, wiring, structure, and service access.
Final Approval
Confirmed before fabrication
Return depth, stroke width, internal system, wall offset, mounting, power, and service access are finalized during production review.
1 / Construction
Three internal systems for the same trimless dual-lit effect.
Each configuration produces an illuminated trimless face and rear halo. The difference is how the LED assemblies are positioned and serviced inside the letter body.
System 1
Dual-Array Trimless Dual-lit Channel Letters
Separate front-facing and rear-facing LED arrays provide dedicated illumination for the trimless face and rear halo.
Cross SectionSeparate front and rear arrays
Dedicated lighting planes support individual face and halo planning.
System 1 · Dual-Array
Finished EffectFinished Dual-Array appearance
The finished exterior appearance is shared across all three systems. The technical difference is the internal LED arrangement.

System 2
Center-Spine Trimless Dual-lit Channel Letters
A centrally positioned carrier supports front and rear illumination from one organized internal assembly.
Cross SectionCentral lighting carrier
The center assembly organizes both lighting directions and wiring.
System 2 · Center-Spine
Finished EffectFinished Center-Spine appearance
The same trimless face and rear halo are maintained while the internal lighting is organized around a central carrier.

System 3
Rear-Carrier Trimless Dual-lit Channel Letters
The primary carrier is positioned toward the rear mounting side, coordinating face illumination with halo output.
Cross SectionRear-positioned carrier
Carrier location is reviewed around face throw, halo clearance, mounting, and service.
System 3 · Rear-Carrier
