Many of our bulb holders have an interior locking mechanism to ensure that they are not inadvertently opened when changing a bulb etc.This mechanism tends to be a small metal or plastic tab on the inside of the bulb holder located to one side of the connection terminal which will make contact to the inside of the twistable section of the holder itself preventing it from turning.

ALWAYS MAKE SURE THE POWER IS ISOLATED BEFORE INSTALLING, CHANGING A BULB OR UNDERTAKING ANY MAINTENANCE WORK ON ANY ELECTRICAL ITEMS.

This tab should temporarily be pushed or bent towards the inside of the bulb holder to allow the unit to be unscrewed and can gentle be pushed back into place once the work is complete however this is not always necessary.

We recommend that any fitting or installation is done by a qualified electrician, do not risk installation yourself if you are at all unsure.

2 core cable does not include an earthing wire and can be used with any electrical item with an outer surface which is predominately made from a non conductive material such as glass, plastic, ceramic or bakelite.3 core cable can be used for these types of fittings also, however a 3 core cable MUST be used with any light, lamp, bulb holder or fitting with a conductive or metal exterior surface to ensure against risk of electrocution or serious injury.We recommend that any fitting or installation is done by a qualified electrician, do not risk installation yourself if you are at all unsure.

When installing one of our multi-way ceiling roses the electrical supply can be split in to multiple connections using a standard connectivity terminal strip, also known as a choc block! 

We recommend that any fitting or installation is done by a qualified electrician, do not risk installation yourself if you are at all unsure.

If any of our lamps, lights or bulb holders do not have an earth connection it will be because the outer surface is predominately made from a non conductive material such as glass, plastic, ceramic or bakelite etc, therefor it is not necessary to earth the unit.If you are using an earthed three core cable with a unit which does not need to be earthed then the earth cable can simply be trimmed back and safely secured using electrical insulation tape.

Any light, lamp, bulb holder or fitting with a conductive or metal exterior surface must always be earthed to ensure against risk of electrocution or serious injury.We recommend that any fitting or installation is done by a qualified electrician, do not risk installation yourself if you are at all unsure.

Many of our lights, lamps, bulb holders, cable and shades are compatible with USA voltage supply and wiring but please contact us by emailing info@dykeanddean.com if you have a specific product that you would like more information about.

However, due to the nature of the technology, our LED bulbs are not currently compatible with the standard US voltage supply ( 120v ). We are however working to include USA compatible UL cert bulbs into our family of Dyke & Dean LED bulbs soon so watch this space!

Our range of Dyke & Dean LED bulbs are all 100% dimmable when used with a compatible dimmer unit.We do tend to find that our bulbs are compatible with most modern LED dimmer units ( manufactured within the last 10 years ), however we recommend the use of an IC constant current trailing edge LED dimmer module.We would always advise that you consult your electrician if you are unsure.

Many of our inline cord and foot switches are earthed however sometimes this is not the case if it is not required ( ie if the switch casing and button is made from a non conductive material such as plastic or bakelite ).All of our products are compliant with UK and EU safety standards, for more details please speak to one of our team by emailing

Dyke & Dean are proud to offer our very own range of LED bulb options, which are both functional, aesthetically pleasing and suitable for a huge range of lamps and interiors.Each individual bulb will carry its own life expectancy guide in our product description. Many of our LED bulbs are guaranteed for around 20,000hrs use however this may be affected by environmental factors such as contact with moisture, incorrect installation and the frequency which the bulbs is turned off and on over time.Incandescent filament bulbs will have a significantly lower life expectancy compared to LED but again the individual life of any bulb will be found in our product description.

We will always aim to ship your cable in one single, continuous length unless you have asked us not to for any reason. Please include this information in the notes section of your order.

Dyke & Dean are proud to offer our very own range of LED bulb options, which are both functional, aesthetically pleasing and suitable for a huge range of lamps and interiors.LED technology is now at a stage where we can offer the same amount of lighting efficiency  ( or lumens ) using only a fraction of the energy making our LED bulbs a less costly, environmentally friendly lighting solution whilst still maintaining the elegance and aesthetic effectiveness of classic lighting design. LED bulbs also have the added benefit of a huge life expectancy so you will be buying less bulbs over time.Each of our LED bulbs has the specific Lumen rating stated in the product description however please feel free to contact our team for advise and recommendations.

LED technology is a great deal more energy efficient, cost effective and environmentally friendly than filament incandescent and halogen bulbs.Dyke & Dean are proud to offer our very own range of LED bulb options, which are both functional, aesthetically pleasing and suitable for a huge range of lamps and interiors.Overtime, reductions to energy costs can be significant and because of the long life expectancy of LED bulbs they will last you up to 5 times longer than other light bulbs, both of which go toward making LED a happier, greener lighting solution.

An IP rating is used to define levels of resistance or sealing effectiveness against moisture, dust and dirt.There are many factors to take into account when considering what level of IP rated light an area will require which is why we always advise our customers to consult a qualified electrician if they are unsure. It is sometimes the case that a specific area, or zone in a bathroom does not require an IP rated light if it is not in the direct vicinity of a source of moisture, however any outdoor lighting not protected by cover would require a high IP rating to ensure its safe installation and effectiveness against prolonged exposure to the elements.

Understanding Light Bulb Base Sizes

The base of a light bulb is a critical factor in ensuring compatibility with your lighting fixture. Common base sizes include:

  • E26/E27: These are the standard sizes for most household bulbs in North America (E26) and Europe (E27). They are typically used in ceiling fixtures, lamps, and pendant lights.
  • B22: The bayonet mount is prevalent in the UK and other countries, featuring two mounting pins and a push-and-twist action for installation.
  • GU10: Known for its twist-lock base, this type is often found in recessed downlighting or spotlights.
  • MR16/GU5.3: These bases are common in low voltage lighting, typically used in track lighting or landscape fixtures.

Light Bulb Shapes and Their Applications

Light bulbs come in various shapes, each designed for specific uses and fixtures:

  • A-Series (A19/A60): The most common household bulb shape, ideal for general lighting.
  • Candle (B/C): These are often used in chandeliers and decorative fixtures for their elegant shape.
  • Globe (G): Globe bulbs are used in bathroom vanities and pendant lights for their spherical shape that provides a wide spread of light.
  • Reflector (R): Designed to direct light, reflector bulbs are used in recessed cans and track lighting.
  • Tube: Fluorescent tube lights are used in kitchens, garages, and commercial spaces for their efficiency in large areas.

Light Bulb Types: LED, CFL, Halogen, and Incandescent

  • LED (Light Emitting Diode): LEDs are highly energy-efficient, have a long lifespan, and come in a range of colors and dimming capabilities. They are suitable for almost all lighting needs.
  • CFL (Compact Fluorescent Lamp): CFLs use less energy than incandescent bulbs and last longer. They take a moment to warm up to full brightness.
  • Halogen: Offering a crisp, white light, halogens are more energy-efficient than incandescents but less so than LEDs and CFLs. They're often used in spotlights and dimmable fixtures.
  • Incandescent: These bulbs provide warm light but are the least energy-efficient, having been phased out in many regions due to energy regulations.

Lumens vs. Watts: Understanding Brightness and Energy Use

Traditionally, bulb brightness was measured in watts, which actually indicates energy use. Today, lumens are the correct measurement for brightness:

  • Lumens (lm): This measures the amount of light a bulb emits. The higher the lumens, the brighter the bulb.
  • Watts (W): This measures how much energy a bulb uses. With energy-efficient bulbs like LEDs and CFLs, you get higher lumens with fewer watts.

Color Temperature: Setting the Mood with Light

Color temperature is measured in Kelvin (K) and affects the mood and functionality of a space:

  • Warm White (2700K - 3000K): Creates a cozy, warm atmosphere, ideal for living rooms and bedrooms.
  • Cool White (3500K - 4100K): A more neutral, inviting light, suitable for kitchens and workspaces.
  • Daylight (5000K - 6500K): Mimics natural daylight, excellent for reading and task lighting where concentration is crucial.
