Product Overview
Sylvania DULUX® T/E lamps combine a compact triple-tube design with the photometric benefits of a longer fluorescent discharge path. This allows fixture designers and maintenance teams to obtain useful light output from compact recessed and task-lighting systems while retaining a 4-pin, externally ballasted configuration.
The lamp uses rare-earth tri-phosphor technology with CRI 82 and is designed for fast run-up to full brightness on compatible electronic ballast systems. The ECOLOGIC® family passes the existing Federal TCLP test and is RoHS compliant according to the manufacturer family sheet.
This is not a self-ballasted screw-in CFL. Correct keyed base and ballast selection are essential because GX24q-1 bases are mechanically keyed for the appropriate wattage family.
