So knowing where to start with brightness can be convoluted. It would also be a good idea to buy spares – as LED technology (as with other technologies such as mobile phones) is always improving and changing.Correlated Colour temperature (CCT) in lighting describes how the colour of the light appears from a lamp, measured in kelvins (K).Imagine a scale from 1000K (very red)  to 10,000K (very blue)  (actual scale is wider). How This range of colours at different temperatures has become useful for describing the colour tint of white light. We delete comments that violate English Instead, to replace a 60W incandescent bulb, you'd be looking for an 8W or 12W LED bulb to get roughly the same lumen rating.

A low colour temperature creates a warm, cosy light effect, while a high colour temperature creates a cool, more energising effect. Cool white bulbs fall in the range of 3100K to 4500K. The problem is, how bright a room should be is subjective and the effectiveness of a bulb is dictated by the size of the room, wall colors, light placement and other factors. The higher the Degrees Kelvin, the whiter the color temperature.

Apart from brightness, you also have to consider the color of the bulbs. Here's what color you need.Not all light bulbs are the same. Color temperature is one of the reasons smart bulbs are such a convenience. Different color temperature light bulbs have different purposes.

Best A cool white light may not make the product look as appealing but it would be a good idea to do some trials to see what works best.Below are some common areas where the different colours can be used:Allow some time to get used to any change especially if changing from warm to cool white.

In commercial applications choosing the right colour temperature is important and will depend on the mood you want to create and the products you are promoting - for example freshly baked cookies and bread may look better under a warm white light.

Daylight bulbs have color temperatures that begin at 4600K and can range up 6500K or higher.

It also seems people from sunnier countries tend to prefer white light compared to people from cooler countries who prefer more warm light. All Integral retail packs have a clear icon and colour temperature indicated on the packaging. In addition, each lamp will have the colour temperature printed on the base e.g. " In other words, you'd probably want daylight bulbs by your vanity or soft white bulbs in your bedroom. Cool white light contains more blue light and looks brighter to the eye (this is why cool white bulbs have a higher lumen output when compared to the equivalent warm white bulb). The higher the lumens, the brighter the bulb. If you've made the Incandescent bulbs use far more power than modern LED bulbs, meaning a 60W incandescent emits less light than a 60W LED bulb.

In a nutshell, we can conclude that Cool White LED lighting best suits practical applications while Warm White is best for living areas. The majority of Philips LED lighting products provides 2700 Kelvin, which is warm white light.

There are no rules - the choice is about personal preference and use. If you like the traditional yellowish colour of a conventional lamp then warm white around (2700-3000K ) would be the ideal choice, this is the most popular choice for homes. And you probably wouldn't want daylight over the dining room table or soft white in the kitchen. Smart The colour of light from an LED lamp is approximated or “correlated” to this scale. Warm: 3000K : Warm White: 4000K: CFL and LED - White: Cool White: 5000K : Daylight: 6000K - 7000K : Cool Daylight: 10,000K: Blue Sky - Blue This is typically denoted by a Kelvin rating (usually 2,700 to 6,500) and accompanied by a descriptive name, such as Here's a breakdown of light bulb color temperature: With that in mind, when choosing light bulbs for a room, think of what you normally do in that space and buy bulbs for that purpose.

And, yes, there is such thing as too much light. The light appears as a bright, neutral white that shades into blue at the upper end of this range. 3000K". However, picking the right bulb doesn't have to be difficult. However, as mentioned earlier, everyone has different tastes.
