Applications
Large Channel Letters
Strokes of 4+ inches: the 170° beam and 12 inch spacing cover big faces with fewer modules, cutting install time on large letter sets.
Sign Cabinets
Pair the Midi 4 with the Midi Stick system for fast, evenly lit single- and double-sided cabinets.
Fluorescent Retrofits
High output per module makes the Midi 4 a strong candidate for HO fluorescent cabinet retrofits. Match existing output with the Lumen Tables.
Frequently Asked Questions
What is the Midi 4 Game Changer?
The TMT Midi 4 Game Changer is a high-output LED module for large channel letters and sign cabinets, available in 1.7W and 2.0W variants at 12V or 24V, producing 250–300 Lm (RevA datasheet) at 155 Lm/W with a 170° beam, IP67 rating, and 5-year warranty. Updated lumen values are pending manufacturer confirmation.
What applications is the Midi 4 Game Changer best for?
The Midi 4 is best for large channel letters with 4+ inch stroke depth, sign cabinets (with the Midi Stick system), and fluorescent retrofit projects where high per-module output reduces total module count.
How many Midi 4 Game Changer modules fit on a 60W power supply?
Official per-model 60W load limits from the datasheet: 32 modules for the 1.7W variant and 27 modules for the 2.0W variant.
What is the beam angle of the Midi 4 Game Changer?
The Midi 4 Game Changer has a 170° beam angle — the widest standard beam in the TMT channel letter lineup — confirmed from the official TMT LEDs USA datasheet.
