Product Overview
The Sylvania 20435 is part of the PENTRON HO SUPERSAVERS High Performance ECOLOGIC lineup, built on the 5/8" diameter T5 miniature bi-pin platform. ECOLOGIC® designates Sylvania's reduced-mercury-dose fluorescent formulation, and this lamp is rated at 30,000 hours average life on 3-hour starts (up to 40,000 hours on 12-hour starts), with 3500K color temperature and 85 CRI for consistent, accurate color rendering.
Lumen output is rated at two ambient temperatures – 4,050 lumens at 25°C/77°F and 4,575 lumens at 35°C/95°F – since T5 fluorescent output varies with the operating temperature inside the fixture. Use the 35°C figure for enclosed or high-ambient-temperature fixtures.
