Before you read about the benefits of full spectrum lighting just read this first about energy saving with these bulbs:

Energy Savings:
Assuming 8p per unit, over 10,000 hours the 23W uses 230KW costing approx £18. A 100W ordinary bulb would use 1000KW costing £80 over the same period. The saving in electricity cost would therefore be £62, which is over 4 times the cost of the bulb.

Dr Norman E. Rosenthal (who originally coined the term SAD) and Dr Thomas Wehr carried out a double blind study of the treatment of SAD in collaboration with the NIMH (National Institute of Mental Health), Psychiatric Institutes of America, New York State Psychiatric Institute and the Walter Reed Army Institute of Research. The results showed that all the patients who spent time under full spectrum light felt considerably better, whilst there was no improvement in the patients using normal artificial light.

Our daylight bulbs have a colour Temperature equivalent to Noon daylight, use 75% less energy then standard bulbs, produce excellent colour rendering and contrast for reading.

* Convenient source of full spectrum light at any time
* Colour Temperature equivalent to Noon daylight (6,000 Kelvin)
* CRI (Colour Rendering Index) of 95
* Full rainbow colour spectrum with accurate natural colours
* High contrast improves visibility and reading comfort
* Uses up to 75% less energy than standard bulbs
* These bulbs last much longer than standard bulbs

Until 150 years ago most people worked outdoors, and obtained enough natural sunlight every day of the year. Windows filter out many parts of the light spectrum.

Professor Dr. Fritz Hollwich, Director of the University Eye Hopsital in Munster, discovered that only around 25% of the light absorbed by our eyes is used directly for vision, the other 75% travels via the optic pathways to the brain and hypothalmus - the body's chief control system. This controls the nervous system and endocrine system, affecting amongs other things our glandular and hormone system.

Irradiation with sunlight increases the number of white blood cells, most of the lymphocytes, causing an upsurge in the defences against infectious diseases. It also stimulates the formation of Interferon, thereby preventing viruses from proliferating.

Our bodies need clear information about day and night in order to regulate our waking and sleeping phases and the biorhythms associated with this. When it is dark more melatonin is produced, which signals to the body that it is time to sleep. On the other hand bright full-spectrum light suppresses the production of melatonin. If parts of the light spectrum are missing, the body can enter a twilight state, comatose, neither fully awake nor asleep.

To summarise the human body has developed over millions of years with daily exposure to natural sunlight. Working indoors has removed much of this natural resource from our lives, but it can be closely replicated with full spectrum bulbs.

N.B. Because these bulbs are energy efficient they produce very little heat, and are therefore safe to use in almost all fittings and with lamp shades if desired

Size approx: 12.5cm x 4.5cm (includes fitting)

IONISER-Bulb, Ioniser Full Spectrum Bulb Wattage and Fitting: 20 Watt Bayonet (same as 90W)

So this 20 Watt Full Spectrum bulb offers a new added benefit - it is also an air ioniser, and produces negative ions!!

Negative ions have the physical proven effect of forcing larger particles and molecules in the air together, so eliminating bad smells and smoke. They also have the effect of killing airborne organisms such as germs, bacteria and viruses. This makes these bulbs very suitable for positioning in food processing areas, medical institutions, toilets, smoking areas, and any confined spaces where airborne germs are a concern such as the workplace.
There is also research (see below) that negative ions have an antidepressant effect for patients with seasonal affective disorder.

Take a look at the research into negative ions here:

Department of Psychiatry, Columbia University, New York.
"Treatment with a high-density negative ionizer appears to act as a specific antidepressant for patients with seasonal affective disorder. The method may be useful as an alternative or supplement to light therapy and medications."
