K Rating For Light Bulbs

Color temperature is a way to describe the light appearance provided by a light bulb.

K rating for light bulbs.

Kelvin ratings are commonly found listed on low energy fluorescent lamps and led lamps. Color differences of led lighting 2 7k 3k 4 3k 5k 6k. Typically kelvin temperatures for commercial and residential lighting applications fall somewhere on a scale from 2000k to 6500k. This light that 3 000 kelvin t5 bulbs emits is significantly lower in kelvins count as previously mentioned 6 500 k bulbs but that also is the reason these bulbs are significantly warmer in their tone.

K is used as a reference number to quickly estimate the light colour of a bulb or led. Light color or color temperature is measured using the kelvin scale. Color temperatures higher than 3500k are typically used for. Headlight bulbs with a colour temperature of 3000k work perfectly well but they may not be as bright as bulbs with a higher kelvin rating.

Here s a color temperature chart for reference. Colour temperature is generally defined by a kelvin rating and is assigned the unit symbol k. Leds are available in warm colors low k to match the yellowish light of incandescent bulbs but you can also choose cooler colors high k with whiter or bluer light. Standard and longlife halogens often fall in this range as do some fog lights.

High performance led replacement bulbs for taillights turn signals brake lights reverse lights license plate lights parking lights drls dome lights and more. K rating for incandescent bulbs above actually hint at the temperatures that their filaments burn at. On the market you can also find bulbs with color temperatures of 2 700 kelvins and 2 900 kelvins that are again essentially the same as 3 000 k bulbs in terms of the light they emit. Halogen bulbs with a colour temperature around 3000k have a yellow colour.

Not so for non black body lighting such as florescent leds. K rating is used to measure color co related temperature cct. Colour temperatures above the 5 000 k mark are cool colours such as whites and blues. It is measured in degrees of kelvin k on a scale from 1 000 to 10 000.

Colours under 5 000 k are warm colours yellowish white all the way down to red. A 6500k t8 florescent light bulb can be cool to the touch it definitely does not burn at 6500 kevins.
