    • Sylvania T5 Pentron Circline Fluorescent Bulbs

    Compare Selected
    Sylvania T5 Pentron Circline Fluorescent Bulbs - Description: SYLVANIA PENTRON® HO T5 lamps were designed to deliver the maximum amount of lumens from the shortest possible length. The result is a lamp that is extremely bright: a PENTRON HO T5 lamp can produce nearly twice the light output of a T8 lamp of similar length, which means that a single PENTRON can often be used in place of two T8 lamps. A one-lamp fixture can be more stylish and compact, and since a single, slender tube is a more concentrated light source, these fixture designs can offer increased optical efficiency.
