When Octron® CURVALUME® lamps are operated on instant start electronic ballasts, system efficacy is maximized. In a typical fixture, the optical and thermal efficiency is improved over standard T12 lamps. These lamps bring T8 technology to a wider variety of fixture configurations. CURVALUME® lamps are ideal for 2 x 2 troffers. Octron® CURVALUME® lamps operate on the same ballasts as linear Octron® T8 lamps providing maintenance ease and color consistency throughout an installation.
