What is the standard length of T8 LED tube

LED tube length standards vary by region, manufacturer, and product type. Normally, it’s as same length as T8 fluorescent tube. This article is mainly to summarize common LED tube length standards in North America, Europe, China, and Japan. Please note that this information is subject to change and it is recommended to refer to the latest standards and manufacturer specifications.

North America

*No mandatory LED tube length standard.

*Usually, it’s influenced by the standard of ANSI (American National Standards Institute) and IES ( Illuminating Engineering Society).

*Common lengths include 24inch, 48inch,60inch and 96inch,etc. The Nominal Length may not exactly match any measured dimension of the tube,as the nominal length (in feet or inch) is the required spacing between centers of the lighting fixtures to create a continuous run, so the real length are a little shorter than the nominal length.

Nominal Length	A(mm)	A(inch)	B(mm)	B(inch)	C(mm)	C(inch)
18inch	389	15.32	404	15.91	25.4	1
24inch	541	21.32	556	21.91	25.4	1
30inch	694	27.32	709	27.91	25.4	1
36inch	846	33.32	861	33.91	25.4	1
42inch	998	39.32	1013	39.91	25.4	1
48inch	1151	45.32	1166	45.91	25.4	1
60inch	1456	57.32	1471	57.91	25.4	1
64inch	1557	61.32	1572	61.91	25.4	1
72inch	1760	69.32	1775	69.91	25.4	1
84inch	2065	81.32	2080	81.91	25.4	1
96inch	2370	93.32	2385	93.91	25.4	1
108inch	2675	105.32	2690	105.91	25.4	1
117inch	2904	114.32	2919	114.91	25.4	1
120inch	2980	117.32	2995	117.91	25.4	1

Europe

*According to European standard IEC 60085, tube size, safety test method and other general requirements are specified in it.

*More important on its efficacy than size, so they released Energy Related Products (ErP) Directive.

*Common lengths include 600mm, 1200mm,1500mm,etc.

Nominal Length	A(mm)	B(mm)	C(mm)
600mm	588	603	25.4
900mm	894	909	25.4
1200mm	1198	1213	25.4
1500mm	1498	1513	25.4
1800mm	1763	1778	25.4
2400mm	2372	2387	25.4

China

*China also has a standard for LED tube, GB/T 26273-2013, it specifies tube’s performance and safety,as well as its lengths.

*Common lengths are the similar to Europe’s

Japan

*JISC 8106:2015 is Japanese standard which stipulates tube length

*Except 1200mm tube, other lengths are different from those in other regions, common lengths are 580mm, 630mm, 830mm.

Nominal Length	B(mm)	D(mm)	D(mm)
134.5mm	134.5	149.5	25.4
210.5mm	210.5	225.5	25.4
287mm	287	302	25.4
330mm	330	345	25.4
436mm	436	451	25.4
580mm	580	595	25.4
630mm	630	645	25.4
830mm	830	845	25.4
1198mm	1198	1213	25.4
1650mm	1650	1665	25.4
2367mm	2367	2382	25.4
