Ushio 26W Compact Fluorescent Bulb CF26D/835 3500K

What it is and who it fits

This Ushio compact fluorescent bulb draws 26 watts and delivers 1800 lumens at a neutral 3500K colour temperature. It suits offices, retail spaces and residential areas that want balanced white light without the harshness of cooler lamps.

The deciding spec: two-pin base

The CF26D/835 uses a dedicated two-pin connector that matches only compatible magnetic or electronic ballasts. Verify the fixture accepts this exact base before ordering; a mismatched socket will prevent the lamp from striking.

Installation notes and common issues

Insert the pins firmly until they seat in the ballast socket; no tools are required. The rated life is 10000 hours, but frequent short cycles and enclosed fixtures without ventilation can reduce actual longevity.
