LEDVANCE offers a wide variety of fluorescent lamps in linear, U-bend and circular types. Our focus has been on providing energy efficient and long life OCTRON® T8 & PENTRON® T5/T5HO fluorescent lamps, enabling end-users to take advantage of immediate energy and maintenance savings at the lowest initial cost, and often in conjunction with utility rebates. Sylvania Fluorescent lamps are optimally paired with OSRAM QUICKTRONIC® electronic ballast offered in standard and dimmable versions. When lamps are paired with QUICKTRONIC® ballasts, the system is covered by the QUICK 60+®, QUICK 7XL,¢ or QUICK 7XL,¢ warranties.For applications where T12 lamps are still needed, Very High Output (VHO) and High Output (HO) Rapid start lamps, as well as Slimline Instant start lamps are available in a variety of lengths. There is a limited selection of 2, 3 and 4 ft Rapid start T12 lamps; most 4 ft T12 lamps have been discontinued since they do not meet the DOE efficacy requirements.
