We've had some really poor tradespeople over the years, so we're always cautious in picking someone. However CD Electrical have done so fantastic work at our house over the last 18 months and the last visit was for a fuse board change and overhaul. We implicitly trust them to conduct the work to the highest standard and electrics is something that we don't want amateurs messing around with in our home. Helpful, polite, courteous, tidy, punctual and completed the job on budget and to a high standard. I know it sounds a little gushing, but I cannot recommend CD Electrical enough. They will be working on a project in our garden later in the year too and we've recommended them to our family and friends too.Read more

Chris turned up at the appointment time and after showing him the bits that needed fixing he got his tools and got on with the jobs. He was quick and neat and kept me updated throughout the job. Even advising what height was best for the new chandelier.Read more

Which outdoor lights are the best?
As long as the fittings are suitably IP rated (waterproof) for the environment they are going in then the world really is your oyster when it comes to outside lights. Below are some of the main examples we use. | Wall Lights | Spike Lights | Flood Lights | Ground Marker Lights | Festoon Lights | LED strips | Spotlights | Once you know what type of light you want or what end result you want to achieve its time to think about: - The colour temperature of the light: Generally cool white, Natural white or Warm white. But how about multi colour changing lights? - The colour finish on the fittings: Black, White, Grey, Green, or how about bare metal finishes like Steel, Bronze or Brass? - How to control them: Switches, Timers, Sensors or Smart controls by Controllers or Phone Apps
How do outside light sensors work?
Outside light sensors are generally split into 3 categories: PIR (Passive Infra-Red), Photocell and Microwave. -PIRs work by detecting movement. These can be setup so they monitor certain areas by fitting at certain heights or points, masking is also available to avoid nuisance activation. The PIRs we generally fit can then be tweaked by 3 settings, Sensitivity (how much movement it takes to trigger) Lux ( When will it trigger, all the time, early evening to late morning, middle of the night) Time ( How long will the the trigger last, usually the options are between 30 seconds to 30 minutes from last detected movement) -Photocells use lux levels (natural lighting levels) to determine switching, so they will come on when natural light levels drop below a certain point. Examples could be if its a particularly cloudy day or middle of winter the lights will trigger at the set levels rather than to a set time period meaning they are on when you need them rather than at the same times everyday. - Microwave sensors use high frequency electromagnetic waves to detect movement, they use a more advanced technology than standard PIRs. And an additional benefit is they can work behind plastic structure of lights without the requirement of a frosted or clear plastic panel for the sensor. Microwave sensors are not used as frequently as traditional PIRs due to cost implications.
What is the best IP rating for outdoor lighting?
The best IP rating is the highest you can achieve. The highest possible grade is IP69K but for general household lighting a more suitable minimum rating would be IP65 up to IP67. IP relates to Ingress Protection, the first number digit refers to the foreign bodies (Solid objects like fingers or tools) or particles (like dust and debris) the second digit refers to moisture ingress, IE water. A rating of IP65 will offer full protection against all foreign bodies, dust and other particulates as well as protection against low pressure water jets from any angle (ie a hose or small domestic pressure washer)
