Ushio CF42TE/841 42W Fluorescent Bulb

This Ushio compact fluorescent bulb delivers 3200 lumens at a 4100K colour temperature. It fits fixtures that accept a GX24Q-4 four-pin base and suits commercial or residential spaces needing cool white light. The lamp is dimmable when paired with a compatible ballast and carries an 82 CRI rating for reasonable colour fidelity.

Installation requires a GX24Q-4 socket

The triple-tube design measures 6.7 inches overall, so verify fixture depth before fitting. A common issue is using a non-dimmable ballast, which prevents dimming and can shorten the 10000-hour rated life. Ensure the ballast supports dimming and that the pins align correctly during insertion.

Sustained output holds near 3200 lumens across

Unlike a short burst, continuous operation at 42 watts maintains stable colour at 4100K with minimal shift. The 82 CRI remains consistent, making the bulb reliable for long daily runs in offices or retail areas. Dimming reduces output smoothly without flicker when the ballast is correctly specified.

Questions about this item

The box contains the 42W triple-tube fluorescent bulb with a GX24Q-4 base; a matching dimmable electronic ballast and a suitable fixture must be bought separately.

Which version of the CF42TE/841 should I choose for my application?
