It is understood traditional light bulbs that we have used for years are being phased out, They have been used either in single or multiple fittings, spotlights or tracker systems. They dont last long in comparison to newer bulbs.They use more energy and get hotter.The new alternatives are energy saving bulbs-which last 10 times longer and use roughly 80% less energy.
There is no doubt that this type of lighting has developed since 1940s when it was first introduced.It is seen to be more efficient than incandescent bulbs e.g. a 36 watt (4ft/1.2m) tube bulb emits the same light as 4x60 watt old bulbs. Exerts taken from the lighting workshop.
Full spectrum is not a technical term when applied to a bulb but a marketing term implying that the product emulates natural light. In current fluorescent lighting a red object will look muted;however, in full spectrum it will be closer to its true colour. There are many manufacturers of full spectrum lights that claim to be the best and closest producer of natural looking light. No surprise as they are in a market competing for business.

June uses her SAD light box as a wonderful stand for the silks to lay across. In class when she taught she draped the silks across the light box to full effect. She also placed a silk on the back of individual chairs and had them at the front of the class for everyone to bathe their eyes on colour while she spoke.
