One Module Family for Every Sign-Lighting Challenge
Compare compact channel-letter modules, high-output cabinet solutions, perimeter edge lighting, and RGB color control in one cohesive Amcad guide. Each family includes real product imagery, application-focused metrics, direct datasheet access, and clear paths to shop or contact us.
TMT Tiny
Narrow strokes. Small footprint. Clean coverage.
Designed for extra-small and thin channel letters, TMT Tiny fits strokes as narrow as 0.5 inch while spreading light evenly across shallow applications. Its compact 8.5 × 16 mm body makes it a practical choice for tight returns, halo details, and small-form lettering.

TMT Mini 2
Small module. High-output channel-letter performance.
Mini 2 is engineered for small and medium channel letters where installers want strong brightness from a compact package. Multiple power, white-temperature, color, and voltage options support a wide range of sign programs without changing the overall family format.

TMT Midi 4
Fewer modules. Lower power. Maximum impact.
Midi 4 is the high-output option for large channel letters, sign cabinets, and fluorescent retrofits. Its broad CrystaLens distribution is designed to reduce hotspots and lower the module count required to reach the desired face brightness.

TMT Midi 3
A balanced workhorse for medium and large letters.
Midi 3 brings wide-angle light distribution, cable management, and Midi Stick compatibility to medium and large channel letters and sign cabinets. It is a straightforward 12V choice when a familiar module format and broad face coverage are priorities.

TMT Midi Edge
Perimeter-mounted illumination for cabinets and lightboxes.
Midi Edge redirects light across the face from the cabinet perimeter rather than lighting directly from the back. The focused optic is intended for single- and double-sided cabinets, retrofits, perimeter illumination, and wall-washer-style applications.

TMT Midi 3 RGB
Vivid color and clean white from one compact module.
Midi 3 RGB is built for channel letters and decorative signage that need dynamic color control without sacrificing broad, uniform illumination. The datasheet positions one module as a replacement for up to three conventional RGB modules, helping reduce wiring and installation time.

Choose by application, depth, and light pattern
The strongest module is not always the right module. Start with the sign geometry and desired light behavior, then confirm spacing, voltage, wattage, color, and quantity against the current datasheet.
| Family | Primary use | Voltage | Efficiency | Optical approach |
