T12 Calculadora de resistencia LED. Tubes

T12 LED tubes modernize the oldest installed fluorescent base — the 38 mm (1.5 in) diameter fixtures common in North American industrial plants, gymnasiums, and big-box retail built before 1990. Our T12 retrofit tubes reuse the existing tombstone sockets, so facilities upgrade to LED efficiency without replacing fixtures, lowering project cost and installation time.Outputs range from 2,200 to 4,800 lumens in 1,200 mm and 2,400 mm lengths, with 0-10V dimming versions for daylight-harvesting controls. Rotatable end caps allow beam direction to be adjusted after mounting — useful for asymmetric aisle lighting. All models meet UL/ETL type A/B/C bypass requirements on request.
