COB downlights: how to choose the right ceiling spot light
For a replacement COB downlight, start with the ceiling hole; for a new light, choose the fitting type. A concealed COB downlight uses one compact LED chip for a single focused beam from a small recessed fitting. We recommend COB downlights for homes.
Is this a new COB light or a replacement?
For a replacement, match the existing ceiling hole before choosing the fitting.
Range numbers in this guide are from 12 November 2026. Browse the COB downlight collection, or use the COB downlight finder to narrow your choices.
Switch off at the board before removing the old light. Measure the round ceiling hole edge to edge across its centre, in mm. Match this measurement to the product's cut-out, rather than its outer rim. For a new installation, plan wire points with your electrician before plaster and paint.
Hole sizes run from about 25 mm to over 150 mm. Sizes of 75 mm and 55 mm are among the most common. Records cover only part of the range, so check the hole size on the product page.
Which type of COB downlight should I choose?
Choose the fitting type first, then the style that suits your ceiling and room.
- Concealed or recessed: the body sits inside the false ceiling; round and square styles suit simple room layouts.
- Deep recessed anti-glare: the LED sits further inside, reducing glare when you look up.
- Trimless: no visible rim, for a flush ceiling finish; fit it while the false ceiling is being made.
- Surface: fixes onto the ceiling, useful where there is no false ceiling.
- Coloured reflector: adds a visible colour inside the light, useful when matching room details.
- Tiltable or adjustable: lets you aim the light towards a wall or feature.
- Multiple-head: groups light heads in one fitting, useful where you want grouped spots.
- Pin hole: has a small visible opening, for a quieter ceiling look.
Panel and SMD downlights remain a choice; explore them through the panel downlight finder.
Which body and reflector colour will suit my room?
After choosing the style, choose the body colour and then the reflector finish.
White and black lead the body options. White suits a light ceiling; black gives a more visible outline. The reflector is the inner part around the light source. Gold adds warmth, white looks simple, black looks darker, and silver adds a metallic detail.
Reflector options vary, check the product page. Choose the finish before comparing sizes and light settings.
Which wattage and size should I buy?
Match the fitting to the ceiling space, then use the room plan to shortlist wattage.
About 7 W to 12 W is a good starting point for home rooms with a normal ceiling. About 15 W to 25 W may suit higher ceilings, shops and showrooms. In our merged range records, 12 W and 7 W are the most offered wattages.
Check the cut-out, outer dimensions and fitting depth before ordering. Use the room lighting planner for a suggested number of lights. Wattage alone does not settle the room layout.
Which light colour should I choose?
Choose warm, neutral or cool light to suit how you use the room.
Eliante offers five light colours: 2700K, 3000K, 4000K, 5000K and 6000K; 3000K is the standard choice. The 2700K and 5000K options cost about 15 percent more. Other ranges list their colours on the product page.
- Warm white: about 2700K to 3000K is a good starting point for living rooms, bedrooms and dining.
- Neutral white: about 4000K suits kitchens, study areas, bathrooms and offices.
- Cool white: about 5000K to 6000K suits work areas, utility rooms and shops wanting bright white light.
Tunable white changes from warm to cool through a remote or app. Essential also offers a 3-in-1 colour switch. Switch it off and on at the wall to change between warm, neutral and cool.
Which control and quality level should I choose?
Choose how you want to operate the light, then check the warranty for that exact option.
With a normal on/off driver, Eliante levels have these warranties: Essential 2 years, Standard 2 years, Performance 3 years, Ultra 5 years. All except Essential use LEDs that show colours more naturally. Compare levels on the Eliante range page.
- Triac: needs a matching wall dimmer; driver warranty is 2 years.
- DALI: needs a control system set up by an electrician or automation installer; driver warranty is 5 years.
- 1-10V: also needs an installed control system; driver warranty is 2 years.
- Remote only: operates by remote on the normal supply; driver warranty is 2 years.
- Remote + app: operates by remote or phone app on the normal supply.
- Zigbee: works with a smart home hub.
Remote + app and Zigbee warranties are 2 or 3 years, depending on the LED chosen. With dimming or smart control, warranty comes from the driver. The product page shows the warranty for each choice; other models vary.
Which beam suits a ceiling spot light?
Choose a focused beam for a feature, or a wider spread for more general room lighting.
A narrow beam of about 15 to 24 degrees can pick out a painting or feature. About 36 degrees is a good starting point for most home rooms. A wide beam of about 60 degrees or more spreads light more evenly.
Beam options vary, check the product page. Discuss where the light should fall before choosing the fitting.
How much does a COB downlight cost in India?
The median listed starting price is about ₹1,450, while your chosen wattage, level and control determine the final price.
These bands use the lowest variant price per product, including GST, on 12 November 2026. Bar lengths show product counts.

How should I choose COB lights for a shop or showroom?
Start with what you want customers to see, then choose the beam and control.
Use the shop and showroom lighting guide to plan display lighting alongside general room light. Share the ceiling plan and display positions before shortlisting fittings.

- Cut-out, fitting depth and outer dimensions checked.
- Wattage and quantity reviewed using the room planner.
