Osram Duluxstar Mini Twist 20W E27 CFL

An Osram Duluxstar Mini Twist 20W E27 CFL — a compact self-ballasted screw-in fluorescent bulb for standard E27 fittings, giving lower running cost than an equivalent incandescent bulb in a more compact spiral shape than a stick-style CFL.

Do I need an electrician for this?

No — this is a standard E27 screw-in bulb with the ballast built in. Switch off, unscrew the old bulb, and screw this one in.

Key Features

FAQ

• Will this fit my existing lamp?
  Yes, if your fitting takes a standard E27 screw-in bulb.
• How is this different from the 23W version?
  Same shape and base, but the 23W lamp draws slightly more power for a brighter output — pick 20W for standard rooms and 23W where more light is needed.
• Is this dimmable?
  Standard integrated-ballast CFLs like this one are generally not dimmable — use it on a standard on/off switch.
• Does it take time to reach full brightness?
  Yes, like most CFLs it builds up to full brightness over roughly a minute after switch-on, rather than lighting instantly like an LED.
