| USA listing (usa.tmtleds.com) | USA | seen 2026-09 | Product page titled 'TMT Midi 4 - Game Changer Channel Letter Module Up to 170 Lm/W' plus datasheet 'TDS-TMT 4 (Midi 4)' published by TMT LEDs USA LLC (Irving, Texas). The page's download link points to www.tmt-leds.com/uploads/midi-4/tmt-4-datasheet.pdf, which did not resolve (DNS failure) on 2026-09-26; the same path on usa.tmtleds.com returned the datasheet. The datasheet's page 4 covers the Aluminum Sticks family (Midi Stick profiles/connectors), not the Midi 4 module. |
| USA listing (tmtledsusa.com) | USA | seen 2026-09 | Product page 'Midi 4 Game Changer' on tmtledsusa.com and its linked datasheet 'TDS-Midi 4' (TMT LEDs USA LLC, www.tmtledsusa.com). This datasheet lists three order codes without the 'TMT-' prefix and different lumen/efficacy values from the usa.tmtleds.com datasheet. |
| Asia listing (tmtledsasia.com) | Asia | seen 2026-09 | Product page 'Midi 4 Game Changer' on tmtledsasia.com. Its download links use the same document file names as tmtleds.com (global datasheet and warranty statement); the tmtledsasia.com copies were not opened separately. |
| US catalog pages 20–21 'TMT MIDI 4 – Less is more' (hosted by ABC Sign Products) | USA | seen 2026-09 | Two-page catalog spread with the footer www.tmtledsusa.com and page numbers 20–21, downloaded from the ABC Sign Products website. The layout matches TMT's catalog style, but the file was not found on a TMT domain, so it is rated D. It lists an additional 24V 3.5 W order code (TMT-107377) not found on TMT's own pages. The spread also has a density-guide grid of module spacing (inches C2C) by letter depth; that grid was not transcribed because its row/column alignment could not be read reliably from the extracted text. Order codes are recorded as rendered on the page (upper-case 'TMT-'); the PDF's embedded text layer stores them in lower case. |
| US distributor listing (ABC Sign Products) | USA | seen 2026-09 | Product table on the ABC Sign Products 'TMT Midi 4' page. It adds a UL model number column and bag quantities; its lumen and lm/W values differ from both TMT's pages and the catalog spread it links to. |
| European distributor listing 'Midi 4 Gold – LED Module, 2W' (Partners Ltd) | Europe | seen 2026-09 | Distributor product page priced in EUR. The page's technical-data PDF link is a copy of the global TMT datasheet (identical SHA-256), yet several values on the page (148 lm, 160°) differ from that datasheet. No order code is given on the page (SKU: N/A). |
Luminous efficacy: usa.tmtleds.com page title states up to 170 Lm/W and its table up to 174 LM/W; the usa.tmtleds.com datasheet features list states up to 200 lumens per watt; tmtleds.com, tmtledsasia.com and the tmtledsusa.com page/datasheet state up to 155 lm/W; the catalog spread states 159 LM/W typical (163 lm/W for TMT-107377).
Possible explanation (not confirmed by a source): The higher figures may reflect a later LED bin or circuit revision sold under the same order codes; the 200 lm/W bullet may refer to a configuration not listed in the table.
Luminous flux: Per-order-code lumen values differ: TMT-105729 is 296 lm (usa.tmtleds.com), 250 lm (tmtledsusa.com, tmtleds.com, ABC Sign Products) or 270 lm (catalog); TMT-105919 is 340 lm (usa.tmtleds.com), 300 lm (tmtledsusa.com, tmtleds.com, catalog) or 310 lm (ABC); TMT-107101 RED is 96 lm (usa.tmtleds.com page), 95 lm (usa.tmtleds.com datasheet), 88 lm (catalog) or 70 lm (ABC). Partners Ltd lists 148 lm at 2W.
Possible explanation (not confirmed by a source): The differences may reflect different product generations or LED bins under unchanged order codes, or different measurement conditions.
Power: Order code 105919 is listed at 2W (12V) in US sources and at 2.4 W / 100mA in the global datasheet; tmtleds.com and tmtledsasia.com list power options 1.68W, 2W, 2.40W; the catalog spread lists 1,7-3.5 W including a 3.5 W 24V order code (TMT-107377) not seen on TMT's own pages.
Possible explanation (not confirmed by a source): The global datasheet may describe an earlier or regional 2.4 W variant; the 3.5 W version may be a newer addition to the range.
Operating temperature: usa.tmtleds.com page lists -22°F to +140°F; the usa.tmtleds.com and tmtledsusa.com datasheets list -40°F ~ +140°F; the global datasheet, catalog spread and Partners Ltd list -30°C to +60°C (numerically the same as -22°F to +140°F).
Possible explanation (not confirmed by a source): The -40°F figure in the US datasheets may be a conversion or editing difference from the -30°C rating.
Modules per strip: usa.tmtleds.com page lists 25 Modules / Strip; all datasheets and the catalog spread list 50 modules per strip, while the catalog's packaging details list 25 pcs per chain for 12V and 50 pcs for 24V.
Possible explanation (not confirmed by a source): The 25-module figure may refer to the 12V chain length described in the catalog packaging details.
Warranty: US datasheets list a 10 YEAR product warranty and 5 YEAR labor warranty and the usa.tmtleds.com page 'Up to 10 Year'; both warranty statements list the Game Changer Midi 4 at 10 Year Parts, 5 Year Labor; the global datasheet shows a 7 YEAR product warranty; the catalog spread shows 5 year; Partners Ltd lists 7 years. The global warranty statement also lists 'Midi 4 Silver' modules at 5 year Parts, 5 Year Labor.
Possible explanation (not confirmed by a source): The different terms may reflect different series (Silver, Gold, Platinum) or regional warranty policies.
Module spacing: US sources list 12" C2C; the global datasheet drawing shows 305 mm; the tmtleds.com and tmtledsasia.com pages list 250mm (changeable upon request); Partners Ltd lists 25 cm.
Possible explanation (not confirmed by a source): 305 mm is approximately 12"; the 250 mm figure may describe a standard chain spacing offered in some markets.
Dimensions: The tmtledsusa.com page lists Module Width 0.08", while its linked datasheet drawing shows 0.79" and the global sources list 20mm.
Possible explanation (not confirmed by a source): The 0.08" value may be a transcription error on the web page.
Recommended depth: US datasheets state channel letters with depths of 3" – 6"; the global datasheet states 7,5 cm to 20 cm; the catalog spread states 3" to 10".
Possible explanation (not confirmed by a source): The ranges may reflect different editions of the application text.
Other: Country of manufacture: the usa.tmtleds.com and tmtledsusa.com datasheets show 'MADE IN EUROPE'; the global datasheet, catalog spread and density guide show 'MADE IN TÜRKİYE'.
Possible explanation (not confirmed by a source): The US datasheets may use a regional label for the same production site.
Beam angle: All TMT sources list 170°; Partners Ltd lists a 160° viewing angle.
Possible explanation (not confirmed by a source): The distributor value may be a transcription error.

Open questions
Gaps: no LED brand/chip, no dimming info, no cable length and no wire gauge in the datasheets (only the usa.tmtleds.com page states 18 AWG). No release date was found in any source. Wayback: the CDX API returned 'Temporarily Offline' during research; the availability API reported no captures for usa.tmtleds.com/tmt-midi-4, the usa.tmtleds.com datasheet or the tmtleds.com product page, and the earliest captures it reported were 2025-09-15 (tmtledsasia.com) and 2026-02-13 (tmtledsusa.com). The CDX API should be re-checked for earlier captures. The usa.tmtleds.com page links its datasheet on www.tmt-leds.com, which did not resolve. The tmtledsusa.com page's product specs were summarized by the fetch tool rather than copied as a raw table, so its inch dimensions (3.31" / 0.08" / 0.45") need human verification. The UL model number BDPCS-12108-070A appears only on the ABC Sign Products page; it was not checked against UL Product iQ (file E491014). The catalog spread's density grid (spacing by letter depth 2"–10"+) was not transcribed. The global warranty statement names a 'Midi 4 Silver' (Game Player) line and 'Gold and Platinum Series' for the Game Changer Midi 4; no separate Silver datasheet or order codes were found. Partners Ltd calls its listing 'Midi 4 Gold'. The reliablesignsupply.com PDF 'midi 4 led module-USA.cdr' was not opened; its file name suggests it is the same file as the tmtledsusa.com datasheet.
