Kelvin Comparisons

I found this and thought it was interesting.

KELVIN (K)
Measurement of light temperature. Every color can be plotted on the Kelvin scale in degrees.

High temperature = cooler (bluer) light.
Low temperature = warmer (yellow/redder) light.

Outdoor Light Source:
8000K - Snow, water, blue sky.
6500K - Large shadows, blue sky.
5500K - Average day light - Central latitudes (5,500 - 6000K light temperature at noon on a cloudless day).
5000K - Noon sunlight.
4500K - Average day light - Northern Hemisphere.
4000K - Early am, late pm, evening sunlight.
3500K - Photofloods.
3000K - Photo lamps.
2500K - Household 150?200w, 60/40w, 25w.
2000K - Candlelight.

Indoor Light Source:
5500K - Xenon flash
5000K - Blue Bulb, Flash cube.
4000K - Fluorescent 'Warm White' Tubes, Clear flash bulbs.
3500K - Photofloods.
3000K - Photo lamps.
2500K - Household 150?200w, 60/40w, 25w.
2000K - Candlelight.

interesting

Where'd you find that? That sounds pretty funny, cause if I had a purple light, that would have a kelvin rating. Pretty cool

I typed in "Kelvin rating" on my search engine and this was an article on the first page rankings.

Nice info - thanks.

just added info, deviating from the ideal color temp which is 6500 kelvin usually or daylight is not that bad i tried it out with my 4000 kelvin 4 pin 36 watt cf to boost my lighting bit time and its working really well ! pearling and everything and the glosso and elatine is carpeting low, i guess more light at a slightly wrong color temp is better then less lighting with the correct color temp
