Ushio 13W Dimmable CFL
The Ushio CF13DE/835 is a 13 watt compact fluorescent bulb with a G24Q-1 quad-pin base. It produces 900 lumens at a 3500K colour temperature and a CRI of 82. The dimmable double-tube design suits commercial and hospitality lighting where adjustable output is required. Rated life is 10000 hours.
Replaces 13W non-dimmable CFLs
Swap this unit for an existing 13 watt plug-in CFL when dimming control is needed. The upgrade is worth it in offices, restaurants or retail displays where light levels must change through the day. It matches the same wattage and pin layout so no ballast change is required. Not for fixtures locked to non-dimmable ballasts.
Fits G24Q-1 electronic ballasts
The four-pin base locks into standard G24Q-1 sockets driven by electronic ballasts. Dimming function depends on a compatible dimming ballast and control system. The ultra-compact double tube frees space in shallow downlights or wall sconces. Not for screw-base sockets or magnetic ballasts without an adapter.

Questions about this item
Does this 13 W bulb use a G24Q-1 4-pin base for electronic ballasts?
Yes, it fits a G24Q-1 quad-pin socket designed for electronic ballasts.
When replacing the lamp, do I need to switch off the electronic ballast first to avoid damaging the new 10 000-hour tube?
Always de-energise the fixture before swapping the lamp; hot-plugging can shorten the 10 000-hour rated life.
After roughly 10 000 hours at 3500 K, should I expect noticeable colour shift or just replace the bulb?
Plan on replacement once output drops near the 10 000-hour mark; colour rendering stays at CRI 82 until end of life.
