spectrum comparison

Under sulphur plasma light melatonin production is suppressed in all mammals (humans), making them 100% alert, free from any Seasonal Affected Disorder and happier, Retail Sales can increase by 40%. The light is almost 100% PUR and thus perfect for photosynthesis. Light can be efficiently distributed over large spaces, superior to all arc-based lamp technology in every sense, and costing no more than lamps which are used extensively in the Film and Theatre industry. Unlike all other artificial light sources, the light output and colour (light output quality) does not degrade over time and it is fully dimmable down to 30%. The lamp is very simple; a hollow quartz sphere with sulphur and argon gas so, unlike all other forms of lighting, it is environmentally benign. The lamp could be crushed to dust and would make a good fertilizer for your garden. It contains no lead, unlike most other lamps, no mercury, unlike all fluorescent lighting and no arsenic unlike most LEDs (Gallium Arsenide).

The sulphur plasma consists mainly of dimer molecules (S2), which generate the light through molecular emission. Because this, instead of atomic emission, is the mechanism of light generation, the emission spectrum is continuous throughout the visible spectrum.

The lamp's output is low in infrared energy, and less than 1% is ultraviolet light. As much as 75% of the emitted radiation is in the visible spectrum, far more than other types of lamps.

The visible light output mimics sunlight better than any other artificial light source, and the lack of harmful ultraviolet radiation can be especially beneficial to museums and displays of art.

The spectral output peaks at 520 nanometers and the correlated colour temperature (CCT) is approximately 6000 kelvin's with a colour rendering index (CRI) of 86.

The lamp can be dimmed to 40% without affecting the light quality, and light output remains constant over the life of the bulb.

UV / IR vs. Visible Light

With almost no ultraviolet and very little infrared light the lamp is easier to use with plastic fixtures or fibres and the best light to display foods, clothes and all forms of art and museum articles without degradation from UV or Infrared Heat.

A Simplified Perspective from Clive Wing:

Spectral Match – How close it is to the power of visible and invisible colours that are in sunlight.
Non-Uniformity of irradiance  - How evenly spread out (distributed) it is.
Temporal Instability – How constant the output is.

A New way of Measuring is Needed

We can not claim higher luminous efficiency than a sodium lamp or higher PAR (Photo synthetically Active Radiation) than a metal halide or sodium lamp because when we measure our plasma lamp in lumens or micro moles it nearly always measures at least 30% less than other HID lamps of the same wattage. We will claim a higher PUR (Photo synthetically Useful Radiation) value because we believe the plasma lamps that we manufacture are the only lamps that are truly a full and continuous spectrum and thus, completely unlike LED's, deliver all of the light that is useful for photosynthesis.

Conventional methods of measuring light for humans use lumens, deemed useless for horticulture, horticulturists measure light in micro moles (µmoles). Working with British, German and Dutch horticulturists and researchers I have learnt that micro mole measurements are the best indicator we have at this time. The results from real world tests indicate that a plasma lamp, that measures 30% micro moles 'less' than a High Power Sodium Lamp of same wattage, produces at least 30% more biomass, and can fully grow cucumbers to European standards 10 days sooner. After eating them myself I can confidently write that in my opinion cucumbers grown in continuous full spectrum light with a low PAR value, compared to HPS, have better aroma, flavour and colour. My hunch is that the nutritional value will be far higher also, especially as thinking it will be the same is disregarding the principles of logic!
