    Well luckily the rest of us get another 5 months of hedonism.

    I never said I would ascend, I just said i'd survive. I think heathens must just be really heavy or something... Mind me to check my weight.
    I have a cunning plan...So cunning you could pin a tail on it and call it a Weasel...

    I've got an OTT Lite too, if all the specialists on the Antique Roadshow use them, they must be the best, right? Joking aside, they're supposed to have the closest to the sun coloured light there is, or at least they did a few years ago when I got it. Either way, I'm happy with it.

    Don't drive yourself nuts with it though...whatever you paint under a certain type of light has very little chance to be viewed under that same light, so all our hard work is for naught in the end (to an extent). Sometimes it's just better to use a regular bulb.

    Myth number 1 = daylight bulbs produce daylight.
    Myth number 2 = CRI is the only thing that matters.
    Myth number 3 = 5600k is white and 3200k is not.
    Myth number 4 = there is such a thing as full spectrum flouresent lights.

    (more info here - http://www.solux.net/daylight_presen...iles/frame.htm)

    At the risk of sounding like we work for them, there is only one near perfect light available now - Solux Bulbs. SoLux is a patented light source that provides an unparalleled replication of natural daylight.

    highlights:
    - used in the Musee d'Orsay, Van Gogh, and Guggenheim Museum.
    - used by Fashion Designers Ralph Lauen and Armani
    - Light source certified as the best daylight source by independent labs, Fortune 500 companies, organizations, and professionals.
    - Only patented daylight source on the market.

    Artist David Schulz :
    "I received the lights yesterday. I am a painter, mostly figurative and
    portraits, and have tried Chromalux (Reveal) and Ott-lite in the past. I have
    a studio with great natural light, but always had to quit painting at
    night because anything I did at night under artificial lighting
    always needed repainting again the next day. This was especially
    true for subtle skin tones. I painted a bit last night on a portrait
    I am working on under your lights and this morning was extremely
    pleased with the results. We will be placing an order shortly for my
    wife's weaving studio as the light we tried over a piece presently on
    her loom as a test looked great. She had been working with the Ott-
    lite after I gave up on it for my painting. Color was never right
    for me and it gave off such weak light for both of us. Thanks. "

    Also beware of these other lights which do not produce "true daylight". (comparisons here - http://www.solux.net/cgi-bin/tlistor...-is-solux.html)

    Actually, they wouldn't - if they knew what they were talking about.


    Myth #3 (more info):
    The apparent color of a source has no correlation to how well it replicates daylight. Basically color temperature alone does not make something exhibit the qualities of "true daylight". The color of 5500K daylight can be described by a point on the chromacity chart, consequently there are literally an infinite number of ways to make sources look like 5500K but with vastly different spectral qualities.

    Have you ever installed a "white" bulb in your kitchen and said "this color looks really blue". Chances are you have. Studies by Sam Berman have dispelled previously held beliefs that retinal cones are exclusively responsible for color vision. As light is dimmed from outdoor light (10000 foot-candles) to indoor light (100 foot-candles) to museum lighting (10-20 foot-candles) the spectral responsivity of the eye shifts from the colored distribution graphed above to the white outlined distribution. In other words, as light is dimmed, the eye is capable of seeing blue more readily. Hence, the textbook 5500K daylight seen outdoors actually looks blue when reduced to indoor lighting levels. This is why Solux developed three daylight conditions, of 4700K, 4100K, and 3500K. As a general rule, 4700K looks white at light levels of 100-150+ foot-candles, 4100K is properly balanced for 50-100 foot-candles and 3500K is daylight balanced for the eye for conditions 50 foot-candles and less.

    So to summarize... Color Temperature, Color Rendering index and the level of illumination all play a part in determining what looks "white".
