Sylvania OCTRON FO25/835/ECO, order code 22139, is a 25W, 36-inch T8 fluorescent lamp with 3500K light, CRI 82 and 2,150 initial lumens. This selected replacement for the generic 735 listing retains the same wattage, nominal length and colour temperature, with improved colour rendering. The existing sales unit is a pack of 30.
For compatible troffers, strips and cove-lighting fixtures, match the G13 medium bi-pin fitting and the ballast’s T8 lamp specification. Rated life depends on the ballast and switching cycle; published examples range from 24,000 to 36,000 hours.
Buying tip: Check the existing ballast designation and 36-inch lamp clearance; match colour temperature with adjacent lamps.
