Ushio CF26DE/841 26W Dimmable Fluorescent Bulb

This Ushio compact fluorescent lamp delivers 1800 lumens at a 4100K cool white colour temperature. It operates at 26 watts with a CRI of 82 and a rated life of 10000 hours. The double-tube design uses a 4-pin base compatible with electronic dimming ballasts.

Suits fixtures with compatible 4-pin electronic

Buyers needing a bulb for standard screw-in sockets or magnetic ballasts cannot use this model. It is not for setups requiring a higher colour rendering index or a warmer colour temperature than 4100K. The fixed 26-watt output also limits use in lower-wattage fixtures.

Verify your fixture accepts a 4-pin double-tube

Confirm the installed ballast is an electronic type rated for 26-watt dimmable operation. Mismatched ballasts will prevent starting or cause premature failure. Ensure the fixture housing accommodates the double-tube form factor.

Questions about this item

What type of ballast must my fixture already have for this 4-pin CF26DE/841 bulb to operate?

The bulb requires an electronic ballast that supports 4-pin double-tube lamps and dimming control.

Can I keep my existing magnetic ballast and still use this 26W fluorescent bulb?

No, magnetic ballasts are not compatible; the lamp needs an electronic ballast designed for 4-pin dimmable operation.

How can I verify the bulb is performing correctly once installed?

The lamp should reach its full 1800 lumen output at 4100K without flicker and dim smoothly through the ballast's range.
