Lightbulb technology


The classic wire filament lightbulb, which has been phased out in favour of more energy-efficient types.


Known for good quality of light, and lasting life compared to tungsten bulbs.

Energy saver/CFL

These brighten as they warm up, use up to a fifth of the energy of tungsten bulbs and last up to 15 times longer.


These offer instant bright light, save up to 90% on energy and last up to five times longer.

Smart bulbs

LED bulbs that you control remotely from your smart device. You can set timers, turn your lights on and off and with some bulbs, create the perfect lighting level and colours to suit your mood.

If You...

  • Want varying light intensity

  • Want to save energy

  • Will install it your living room, bedroom or dining room

Then consider a dimmer, because dimming a light bulb normally reduces energy consumption and you can quickly and easily change the mood of the room.

If You...

  • Want to control the same light from 2 or 3 locations
  • Need to control the lighting in your appliance

Then consider a switch. Fridges and ovens sometimes need higher-rated switches. We offer a 20-amp double pole switch with a neon indicator, or for appliances that require a 13 amp fuse, switched fused spurs are included in the assortment.

What wattage rating do I need?

  • The total wattage to be used by the switch/dimmer (eg 1x 10 arm light rated at 20 watt each = total 200 watts) and should not exceed this
  • Some mains voltage Halogen lights require dimmers that run at double their total wattage
  • Consult a qualified electrician for further advice

Can I use a dimmer with fluorescent lighting (energy saving bulbs CFL)?

Only dimmable CFLs can be dimmed using a Varilight V-Pro dimmer

What types of lighting can I control using a dimmer?

  • Varilight V-Pro series dimmers are programmable with a choice of dimming modes
  • They have an adjustable minimum brightness setting for the widest compatibility
  • All V-Pro dimmers offer superior dimming technology to deliver the best possible dimming performance for a given load
  • V-Pro dimmers are suitable for mains lighting, most dimmable electronic transformers and dimmable low energy lighting, including dimmable LEDs
  • Always choose LEDs that are described as 'dimmable'
  • V-Pro dimmers are not suitable for wire-wound "toroidal" transformers, non-dimmable fluorescent lighting, energy saving bulbs and fans
  • Mixed loads are not recommended

How do I control dimmable electronic transformers?

  • To calculate the load of your lighting when using transformer in a circuit, add the VA ratings of the transformers (not the wattage of the bulbs)
  • Follow the halogen rating guidelines above, but with a maximum of 5 fully dimmable electronic transformers per dimmer circuit

What is a programmable dimmer?

  • The V-Pro dimmer series have three different dimming modes can be set by the user, as well as a programmable minimum brightness setting, to optimise performance and deliver the full dimming range potential of a particular lighting load.
  • Follow the steps outlined under the heading 'Programming' on the instruction leaflet

Environmental information

  • CFL bulbs contain a minute amount of mercury
  • All our bulbs are well within the safe, legal limit of 5mg
  • CFL bulbs also emit a minimal amount ultraviolet radiation
  • As a precaution keep them at least 30cm away from exposed skin

Safety Tips

If your dimmer is buzzing…

  • Some dimmers will emit a hum when turned to their lowest setting
  • This is quite normal for some types of dimmer - it may vary in intensity depending on the type of lighting unit being dimmed
  • Change to a V-Pro dimmer to alleviate the problem

If you break a CFL bulb...

  • Ventilate the room for 20 - 30 minutes
  • Always use gloves to remove debris and dispose of by recycling

General light bulb advice

  • Dust on the surface of a bulb could reduce the bulb output by 50%, so keep them dust free
  • Clean light bulbs with a dry cloth only
  • Before removing a bulb from a fixture, turn it off and allow it to cool 
  • Consider LEDs for children’s rooms - they don’t get as hot as other types of bulbs 
  • If you break a CFL bulb, ventilate the room for 20—30 minutes and use gloves to remove debris - remember to recycle it afterwards
  • Use a plug timer to fit over your existing lamp plug socket for security and energy-saving purposes - alternatively use an electronic timer or smart lighting 
  • Turn incandescent and halogen bulbs off when you’re not using them - they’re less efficient than CFLs and LEDs


All CFL and LED bulbs should be recycled at your nearest recycling bank, which will be found at (please note that we can't be responsible for the content of external websites)
