Frequently asked questions

  • Will dimmers or control systems save me money?

    Dimmers and control systems can contribute to a cost saving for electricity use as you only use the required amount of power required for the effect you are looking to create.

  • What are Part L Building Regulations?

    Since April 2010, at least three in four light fittings in new and refurbished homes must be energy efficient (Part L Building Regulations). John Cullen’s range of energy efficient fittings are not only practical but also decorative and well-designed. They are ideal green solutions for anyone renovating a house.

    Our designers will always discuss regulation requirements but ultimately it is the client’s responsibility to ensure contact with their local authorities building control service inspector as they do vary from region to region, inspector to inspector.

  • How can I light my artwork?

    There are many options that can be found in our artwork lighting section within our product pages. These fittings range from surface mounted, recessed to picture mounted. At JCL we have every option available to light artwork effectively and discreetly.

  • What does layering light mean?

    Layering light allows you to make the most of architectural and interior features in a room.

    A simple example of layering could be in a bedroom. Pendants or downlights give a functional light, whilst the addition of a bedside lamp will open out the space and create a warmer, cosier atmosphere.

    Light sources can be positioned in or on ceilings, on walls at night, mid or low level and could also be recessed into floors or walls at low level.

    By adding dimmers to all lighting circuits you produce further combinations of atmosphere. Evening lights could have a 5 amp circuit on a warm soft level, while the functional light source is either off or very dimmed. For daytime, the functional lighting would be at a much brighter output.

    For a more detailed explanation of how to layer with light, see our news pages.

  • Do I need a plan for the lighting design service?

    A floor plan is always required to produce a lighting design, as we mark them up with the exact position, circuit number and lamp requirements for each fitting specified. If you do not already have one produced by an architect, estate agent or yourselves, you must have a site visit so that we can measure up the space for you. Any size plan is helpful, but a minimum scale of 1:50 is required to ensure all of the information marked is clearly visible to your electrician or contractor for installation.

  • What is the difference between a designer and a senior designer?

    All designers at John Cullen have been fully trained for lighting design. Senior designers just have more experience than designers, and therefore always work on listed or new build properties, as these types of developments either require greater detailing or adaptations.
