Illustrative render – not an official product photo

TMT describes the Midi Edge as an edge-lit module installed on the perimeter of sign cabinets and lightboxes, in 12V (105737, 105738) and 24V (105857) 6500K versions. The global datasheet lists 240-320 lm at 140-155 lm/W with a 20° x 45° beam; usa.tmtleds.com lists 296-435 lm at 170-181 lm/W for the same order codes and states a 15° x 45° beam.

Revisions & regional differences

TMT publishes product information on several regional websites and in datasheets. Where they differ, each description is kept as its own revision instead of choosing one value.

RevisionRegionPeriodNotes
Global listing (tmtleds.com) and TMT Elektronik datasheet TDS-Midi EdgeGlobalseen 2026-09—
USA listing (tmtledsusa.com) and TMT LEDs USA datasheet TDS-Midi EdgeUSAseen 2026-09Datasheet table matches the global datasheet except modules per foot (2) instead of modules per meter.
USA listing (usa.tmtleds.com) and datasheet TDS-TMT EdgeUSAseen 2026-09Same three order codes as other markets, prefixed 'TMT-', with higher lumen and lm/W values. The page table lists 434 LM for TMT-105738 while the datasheet lists 435.
Asia listing (tmtledsasia.com)Asiaseen 2026-09Values match the global page except the description text, which states an 18° X 40° beam angle.
US distributor ABC Sign Products (listing and hosted TMT catalog page)USAseen 2026-09The catalog spread (pages 30-31) and the distributor's own table give different lumen and lm/W values from each other and from TMT's sites.

Luminous efficacy: Global/asia/tmtledsusa.com pages list 155 Lm/W; global and tmtledsusa.com datasheets list up to 150 lumens per watt in text and 155 / 140 / 150 in the table; usa.tmtleds.com lists up to 159 Lm/W in text and 174 / 181 / 170 in its tables; the catalog lists 159 / 142 / 150; the ABC listing shows 125 / 160 / 155.

Possible explanation (not confirmed by a source): May reflect different product revisions or LED bins under the same order codes.

Luminous flux: For 105737 / 105738 / 105857: global and tmtledsusa.com datasheets list 240 / 320 / 300 lm; usa.tmtleds.com lists 296 / 434 (page) or 435 (datasheet) / 340; the catalog lists 270 / 340 / 300; the ABC listing shows 250 / 320 / 310.

Possible explanation (not confirmed by a source): May reflect different revisions of the same order codes.

Power: 12V low-power variant is listed as 1.68W (global, asia, tmtledsusa.com) and 1.7W (usa.tmtleds.com, catalog, ABC).

Possible explanation (not confirmed by a source): May be rounding.

Beam angle: Global page and datasheet list 20° x 45°; asia and tmtledsusa.com pages list 20°x45° in the spec table but 18° X 40° in the description; the tmtledsusa.com and usa.tmtleds.com datasheets show 18° x 40° in the spec band and 20 x 45 in the polar diagram; the usa.tmtleds.com page, its datasheet description and the catalog list 15° x 45°.

Possible explanation (not confirmed by a source): May reflect an optics change that was not applied consistently across documents.

Power supply loading: Modules per 60W supply: 32 / 25 / 27 on the global and tmtledsusa.com datasheets; 30 / 21 / 25 on the usa.tmtleds.com page and the catalog.

Possible explanation (not confirmed by a source): May follow from the different wattage/loading assumptions.

Modules per strip: Datasheets list 25 Modules/Strip (bag 4x25); the usa.tmtleds.com page and catalog list 50 modules / strip; ABC lists bag qty 25x2=50 or 50 x 2 - 100.

Height: Height: 14mm (global/asia pages), 11.5 mm (global datasheet), 0.55" (tmtledsusa.com page), 0.45" (tmtledsusa.com datasheet), 0.54" (usa.tmtleds.com datasheet).

Possible explanation (not confirmed by a source): May reflect measurement with or without mounting features.

Module spacing: 175mm (global/asia), 7" / 7.00" (tmtledsusa.com, usa.tmtleds.com datasheet), 7.01" (usa.tmtleds.com page), 6.9" / 6.88" (catalog).

Possible explanation (not confirmed by a source): May be rounding between metric and imperial values.

Operating temperature: Global datasheet and catalog list -30°C ~ +60°C; usa.tmtleds.com page lists -22°F to +140°F; both US datasheets list -40°F ~ +140°F.

Warranty: Pages and catalog list 5 years ('Up to 5 Year' on usa.tmtleds.com); the global datasheet shows a 5 year product warranty badge; the usa.tmtleds.com datasheet shows 7 year product / 5 year labor; all warranty statements list 7 Year Parts, 5 Year Labor for Midi EDGE.

Possible explanation (not confirmed by a source): May reflect parts vs. labor terms or different series.

Recommended depth: Global datasheet: cabinets from 7,5 cm and perimeter lighting 'up to 17,5 cm Across'; US datasheets: from 3" and 'up to 7" Across'; all datasheets also print '4'' Depth 7' Across' and describe illumination 'up to 7 feet across'.

Possible explanation (not confirmed by a source): The 7" / 17,5 cm figures may be a unit error for 7 feet.

Other: Country of manufacture printed: 'MADE IN TÜRKİYE' (global datasheet, catalog) vs 'MADE IN EUROPE' (usa.tmtleds.com datasheet).

Wayback Machine: web.archive.org could not be reached via WebFetch and the CDX API returned an 'Internet Archive: Temporarily Offline' page on 2026-09-26, so no first_archived event was recorded. No printed dates on any datasheet; PDF metadata dates (global 2023-03-18, tmtledsusa 2023-04-13, usa.tmtleds.com 2026-09-09) are in source notes only. No release date found. The usa.tmtleds.com page text claimed a datasheet at www.tmt-leds.com/uploads/midi-edge/...; that host did not resolve, the actual href is the relative path /uploads/midi-edge/tmt-edge-datasheet.pdf on usa.tmtleds.com. Not found: LED chip brand, LED count per module as a stated value, cable length, wire gauge, certificate PDFs, generation number. Distributors seen but not used: kgsupplies.com (repeats TMT page text), amcadgraphics.com product page returned 404. The ABC 'UL Model Number' values were read through a text-extraction tool and should be re-checked.
