Lighting Selection Guide: Height, Spacing, Colour & Dimming

Beautiful lighting starts with proportion, a comfortable glow and controls that work together. Use this guide to build your shortlist, whether you are choosing a single sculptural pendant or a considered row above a dining table.

The measurements below are styling starting points, not installation requirements. Follow the fitting manufacturer's instructions and have a qualified electrician assess the location, mounting and electrical compatibility.

Your lighting selector at a glance

Quick choices for a balanced lighting scheme
Decision Starting point Check before ordering
Pendant above a dining table Try 75–90 cm from tabletop to the lowest point of the fitting. Seated sightlines, shade height and available suspension range.
Several pendants For small or medium shades, mock up 60–90 cm centre-to-centre, then adjust to the table. Shade diameter, clear gaps and equal end margins.
Living room or bedroom 2700–3000K for a warm, relaxed starting point. Exact Kelvin option and brightness in lumens.
Dining room 2700–3000K for a warm evening setting. Dimmability if you want adjustable brightness.
Kitchen or home office 3000–4000K, depending on whether you prefer warmer or more neutral light. Task lighting, glare and consistency with nearby lights.
Bathroom or dressing area 3000–4000K as a colour preference, with well-positioned mirror lighting. Have a qualified electrician confirm suitability for the exact location.
Dimmer control Choose an explicitly dimmable light source and a matching control system. Manufacturer-confirmed bulb, driver and dimmer compatibility.

1. Set the pendant height

Above a dining table, begin with the bottom of the fitting around 75–90 cm above the tabletop. Try a temporary, non-electrical mock-up before installation: sit at the table and check that the shade does not interrupt conversation or create an uncomfortable view of the light source. Larger shades and different ceiling heights may call for a different position.

Calculate the total drop you need: floor-to-ceiling height minus table height minus your chosen tabletop clearance. For example, a 240 cm ceiling, a 75 cm table and an 80 cm clearance leave an 85 cm total drop from ceiling to the bottom of the fitting. Compare this with the product's overall minimum and maximum drop, not cord length alone; the canopy and shade also take up height.

Over an island, a styling starting point is roughly 80–100 cm above the worktop, adjusted for standing sightlines and the task below. Do not apply tabletop measurements to walkways, stairs or open circulation areas. Have your installer determine appropriate positioning and clearances there.

2. Balance spacing over the dining table

Centre the lighting composition on the table rather than automatically on the room. One larger pendant can give a compact table a clear focal point. Two or three smaller pendants can distribute the composition along a longer table.

Measure spacing from the centre of one fitting to the centre of the next. For small or medium pendants, 60–90 cm is a useful mock-up range, not a rule. Wider shades need more space. Leave visible gaps between shades and keep the outside edges of the arrangement comfortably inside the table ends.

For a precise layout, choose equal centre-to-centre spacing and calculate the end offset: (table length − (number of pendants − 1) × spacing) ÷ 2. On a 200 cm table, three pendants at 65 cm centres place the outer pendant centres 35 cm from each end. With 25 cm shades, that leaves 22.5 cm from each outer shade edge to the table end. Check the table width too, then test the arrangement at full scale before committing.

3. Choose colour temperature by room

Kelvin (K) describes how warm or cool white light appears; it does not describe brightness. Lower numbers look warmer, while higher numbers look cooler. Compare lumens separately when choosing how much light you need.

For a cohesive home, start with 2700–3000K in bedrooms, living rooms and dining areas. Consider 3000–4000K for kitchens, work areas and mirror lighting if you prefer a more neutral appearance. These are design preferences rather than fixed room rules. A 6000K option has a much cooler appearance and is a deliberate aesthetic choice, not an automatic upgrade for a workspace.

Keep lights visible together at similar colour temperatures unless contrast is intentional. Wall colours, shade materials and daylight affect the result, so test a sample where possible. A warm-looking shade is not proof of a particular Kelvin value. Check the exact product option: some lights have a fixed temperature, some offer a choice at purchase, and others allow adjustment after installation.

4. Check dimmer and LED-driver compatibility

LED does not automatically mean dimmable. A fitting with a replaceable bulb and an integrated LED fitting need different checks. An E27 bulb cap describes the connection, not dimming compatibility.

  1. Read the product's dimming specification. If it is listed as non-dimmable, do not assume that changing a bulb or adding a wall dimmer will make it dimmable.
  2. For replaceable bulbs: confirm that the fitting permits the proposed arrangement, choose an explicitly dimmable LED bulb of the specified cap type and permitted rating, and check the bulb manufacturer's compatible dimmers.
  3. For integrated LED fittings: confirm whether the supplied driver supports dimming and which control method it requires. Phase-cut, DALI and 0–10V controls are not interchangeable. Even leading-edge and trailing-edge dimmers should not be assumed compatible.
  4. Match the whole system: ask your electrician to check the exact fitting, bulb or driver, dimmer model, LED load range and number of fittings on the circuit. Do not choose a replacement driver by wattage alone; its output characteristics and control method must also match the manufacturer's requirements.
  5. Check the expected performance: confirm the supported dimming range and whether the proposed combination has been tested for flicker, buzzing or dropout. Dimming usually changes brightness, not Kelvin; a warmer colour as brightness falls requires an explicitly specified dim-to-warm feature.

A remote control, selectable colour temperature or a smart bulb does not by itself confirm compatibility with a wall dimmer. Ask for written confirmation of the exact combination before buying controls. Leave wiring, driver changes and installation to a qualified electrician.

Explore lighting for your scheme

Nordic Minimalist Disc Pendant Light: the current listing offers 25 cm or 40 cm diameters and 3000K, 4000K or 6000K light-tone options. The LED is included and the fitting is listed as non-dimmable. Consider it when comparing shade scale and fixed light-temperature choices; select the exact size and light-tone option before ordering.

Industrial Retro Cage Pendant: the current listing specifies a 30 cm shade, an adjustable cord up to 110 cm and an E27 bulb holder, with the bulb purchased separately. It is listed as non-dimmable as supplied. Consider it when an adjustable drop and a separately chosen bulb colour temperature matter; do not treat the E27 holder as confirmation of dimmer compatibility.

Product options and specifications can change. Recheck the current listing and manufacturer instructions for the exact variant you select.

Your before-you-buy checklist

  • Record ceiling height, table or worktop height, and furniture length and width.
  • Choose shade diameter, total drop and a tested spacing layout.
  • Select Kelvin for the mood, then lumens for brightness.
  • Confirm bulb inclusion, cap type or integrated LED details.
  • If dimming matters, obtain confirmation for the exact light source, driver and control combination.
  • Have a qualified electrician confirm installation suitability, mounting and any location-specific requirements before installation.
