Which is better for Diwali, warm white or cool white?

Warm white, without question. Diwali lighting is meant to echo diyas and candlelight, which sit around 2200–2700K. Cool white reads as clinical against traditional decor.

Is warm white or cool white brighter?

Neither. Brightness is measured in lumens and is independent of colour temperature. Cool white often appears brighter to the eye at the same lumen output, which is why it suits security lighting.

What colour temperature for outdoor gate lights?

6500K cool white for security and visibility, or 4500K neutral if the gate faces a home you want to look welcoming rather than institutional.

Warm white vs cool white: which to buy for which room

Updated 26 August 2026

Short answer: warm white (around 2700K) for living rooms, bedrooms, balconies and every festive occasion. Cool white (around 6500K) for gates, facades, security lighting, kitchens and workshops. If you are decorating for Diwali or a wedding, you want warm white, cool white photographs blue and makes a home look like a car park.

What Kelvin actually measures

Colour temperature is measured in Kelvin, and the scale is counter-intuitive: lower numbers are warmer and more orange, higher numbers are cooler and more blue. It has nothing to do with how bright a light is or how much power it draws, a 2700K and a 6500K bulb can be identical in every other respect.

The practical scale

Temperature	Looks like	Use it for
2200K	Candle flame, deep amber	Diyas, festive corners, mood lighting
2700K	Warm white, classic bulb	Living rooms, bedrooms, balconies, Diwali
3500K	Soft white, gentle	Bedrooms, cove lighting, dining
4500K	Neutral, paper-white	Kitchens, study desks, bathrooms
6500K	Cool white, daylight	Gates, facades, security, workshops

The mistake almost everyone makes

Mixing temperatures in one line of sight. A warm white string on the balcony railing next to a cool white focus light on the wall behind it looks broken, the eye reads one of them as dirty or faulty. Pick a temperature per space and stay on it. If you genuinely need both, separate them so they are never in the same view.

Why product photos cannot be trusted

Almost every decorative lighting listing online is shot with a long exposure and colour-graded warm, because warm light photographs beautifully. A cool white string photographed that way looks warm on the listing and blue on your balcony. This is exactly why we built a colour temperature slider on the homepage instead of relying on photographs.

For photography and video

If you are lighting a space that will be photographed, a wedding backdrop, a shop, a reel, warm white at 2700K is almost always the answer. Skin tones look healthy under warm light and sickly under cool. Cool white is for when accurate detail matters more than how people look.
