PLASMA INTERNATIONAL
esp - sky light (fr) prototype PLASMA INTERNATIONAL There is a lot of debate over the true usefulness and practical application of Colour Rendering Index (CRI). Incandescent bulbs have a CRI rating of 100, yet are far from ideal for colour rendering and matching. Why? With a colour temperature of only 2700k they are far too weak at the blue end of the spectrum making it next to impossible to distinguish between various shades of blue. The CRI rating of 100 simply means that 8 colours (see fig.1) look exactly the same as they would under a black body radiator at 2700k.

The same can be said for lamps that exceed 6500k in colour temperature as they are too weak in the red end of the spectrum, making reds and oranges appear too similar creating a "washed out" appearance. The northern sky with a colour temperature of about 7500k and a CRI of 100 is not necessarily the ideal colour rendering light source either. An ideal light source for colour rendering will have both a colour temperature similar to daylight (5000K to 6000K) and a high CRI value (>85).

Regardless of whether or not CRI is the fairest measure of colour rendering for luminaires, it is important for specification, compliance and certification purposes. The US Department of Energy’s Energy Star program, offers generous manufacturer and consumer enticements for developing and installing and high-efficiency lighting products. CRI is one of the criteria , so you need to ensure you address CRI and efficacy issues at design time. For example, to be Energy Star listed, kitchen luminaires and portable task lamps need a CRI of 80, outdoor pathway lights and ceiling down lights require a CRI of 70.

Sulphur Plasma spectrum is full and continuous and excellent for all types of photography and filming. Measured at 8m from source a 1.2KW Xenon lamp measured 10,000 lumens on the subject. When the 1.2KW Xenon was replaced with a 1.3KW PI-VL greater than 50,000 lumens was measured on the subject. Source: TV Film Studio Hamburg Germany 2008.

German Attention to Detail
A beautiful, full and continuous spectrum, the closest to natural daylight achievable. Because this is a wirelessly powered light source with no electrodes the plasma inside the bulb is never contaminated by burnt or damaged electrode debris. The light quality remains pure and perfect, unchanging and no degradation, a superiorly constant output. The special ingredients inside the bulb are >99.6% pure, the German optics (patented) are the best.

No other singular artificial light source is capable of delivering so much light from such a small point of source, lending itself to many focal variances.
