Dimmer Dimmable Energy Saver - 20W - Bayonet
Dimmer Dimmable Energy Saver - 20W - Screw



Dimensions: 32 x 124mm

It'll dim from 2% to 100% brightness and will save you more than £100 on energy bills over its life! Equivalent to a 100W 'normal' bulb, it'll last 16,000 hours.

  • Wattage (W): 20
  • Lumen Output (lm): 1300
  • Energy Label (Class): A
  • Diameter (mm): 54
  • Length (mm): 124
  • Lifetime: 16,000h
  • Colour: 2700K Warm white
  • Switch on at any light level
  • Low mercury content only 2.5mg
  • 100W incandescent equivalent
  • Will work with most slider dimmers and touch dimmers.

At the end of its useful life, this energy saving lightbulb should be recycled at any household recycling site. (This is a big difference between tungsten bulbs and compact fluorescents (CFLs) - you can actually recycle CFLs whilst tungsten bulbs can only go in the bin.)

Whilst every attempt has been made to ensure these bulbs work with the majority of dimmers (and this bulb will work with most standard dimmer switches) some dimmers may require more than one bulb to be used to meet their minimum wattage - if in doubt, please check the instructions on your dimmer switch).

  They work  I wasn't sure if the bulbs would work with my remote-controlled dimmer switches. I need not have worried; they work perfectly. Do take note of the MINIMUM load of your dimmer switch, I'm using 2 bulbs in the circuit (40 watt load).    John -

  Brilliant  These bulbs give out plenty of light. I use 2 per circuit (40 watts) and they work perfectly with my remote-controlled dimmer switches.    -

  Very good  Despite problems with getting the right switch I am very happy with the results. The varilight touch dimmer switch has made this a most worthwhile purchase but beware the standard dimmer switches!    vaughan - devon

  Good product  Quite expensive, but works well with my dimmable switches. The bulb is well packaged to prevent damage while in transit. I hope they last as long as advertised...    -

  important note  Be aware that this low energy bulb won't work with most standard dimmer switches. There are maximum and minimum requirements and most standard switches are rated at 60 watt minimum which means you'll need to run at least three bulbs on one circuit. Low rated switches are available from Varilight.    vaughan gallavan -

  Seems to work  I have just tried this with GET electronic dimmer switches and they seem to work fine (Megaman will not). Good birghtness too. Would have been 5 stars but don't yet know how long they will work for!    -

  Brilliant  An excellent idea. I hated the thought of having to use an ordinary bulb in our living room just because I wanted to dim it in the evening. Works well and saves loads of money    Sally Daffarn -
