TMT LEDs publishes product information on four domains. They share a brand but not always the same product list, names or figures. This article describes what each domain covered on 2026-09-26 and how this independent site handles values that differ between them.

The four domains

Domain What it covers (as observed) Source
tmtleds.com Global site with product catalogue, About, Production and Technology pages tmtleds.com
usa.tmtleds.com Separately built US site with Company, Support & Resources, TMT Linera, “How to Buy” and a layout service usa.tmtleds.com
tmtledsusa.com Same template and product catalogue as tmtleds.com; footer “Copyright © 2023 TMT LEDs USA” tmtledsusa.com
tmtledsasia.com Same template as tmtleds.com; footer “Copyright © 2023 TMT LEDs ASIA”; homepage links an LED Lightbox Modules category tmtledsasia.com

The global site lists Mini 2, Midi 4 and Midi Edge (Game Changer), Mini 3 and Midi 3 (Game Player), and Slim, Slim+ and Tiny under LED Signage Modules (tmtleds.com LED Signage Modules). It also has an LED Lightbox Modules category with back-lit, edge-lit and linear modules, which is not in the global homepage menu but is linked from the Asia homepage (tmtleds.com Lightbox Modules; tmtledsasia.com Lightbox Modules).

The US site uses plain names such as “TMT Mini 2” and “TMT Midi 4” and lists Tiny, Mini 2, Midi 4, Midi 3, Midi Edge and Midi 3 RGB (usa.tmtleds.com LED Signage Modules). It adds TMT Linera, Midi Stick cabinet parts, LDM-series Class 2 power supplies, and support pages such as FAQ, Application Guide, Density Guidelines and Warranty Statement (TMT Linera; Sign Cabinet & Lightbox Products; Power Supplies; Support & Resources).

Where the domains differ

Examples of values that differ between official TMT sources:

Item Values found Sources
Midi 4 efficacy up to 155 lm/W; up to 170 lm/W; up to 174 lm/W Midi 4 datasheet; usa.tmtleds.com listing; usa.tmtleds.com Midi 4
Midi 3 efficacy up to 122 lm/W; up to 125 lm/W; 113 lm/W Midi 3 datasheet; tmtleds.com category; usa.tmtleds.com Midi 3
Midi Edge beam angle 20° × 45°; 18° × 40°; 15° × 45° Midi Edge datasheet; tmtleds.com Midi Edge; usa.tmtleds.com Midi Edge
Mini 2 warranty 10-year product / 5-year labour; 5 years; “up to 10 year” Mini 2 datasheet; tmtleds.com Mini 2; usa.tmtleds.com Mini 2
Tiny depth 1–3 in.; 1.5–3 in. tmtleds.com Tiny; usa.tmtleds.com Tiny

The Midi Edge datasheet itself gives 20° × 45° in its text and polar chart but 18° × 40° in a header bar on page 2 (Midi Edge datasheet).

Power supplies are also presented three ways: OMS-EP 12 V models on the global category page, LDM Class 2 models on the US site, and LDM Silver/Gold models in the warranty statement (tmtleds.com Power Supplies; usa.tmtleds.com Power Supplies; warranty statement PDF).

Possible reasons for differences

No TMT source explains these differences. Possible explanations, none confirmed, include pages written at different times, different product revisions or configurations, regional product ranges, or rounding and unit conversion between metric and imperial versions. The About pages themselves show one timing effect: the global page cites 15 years of experience and the US page 17, both counted from 2008 (tmtleds.com About; usa.tmtleds.com Company).

How TMTLED.com handles it

This site does not choose a “correct” value when official sources disagree. Each product page keeps the values from each market as separate revisions, cites the source for every value, and lists the conflict with any explanation phrased only as a possibility. Datasheets (level A) are shown alongside website values (level B) rather than overriding them. Readers should confirm critical figures with TMT or an authorised distributor for their region. For the company background, see TMT LEDs – Company Background.
