Product Overview

DULUX® T/E/IN lamps are pin-based compact fluorescents. The 4-pin lamps have no internal starter; starting is a function of the ballast. They are designed for electronic ballast operation and are dimmable per the manufacturer catalog. This lamp is not a self-ballasted screw-in CFL.

This is an amalgam lamp for electronic ballasts in high and low temperature applications. Optimum light output occurs at approximately 35°C / 95°F ambient temperature with the lamp operated base-up; the lumen value listed at 35°C is the optimum output.
