Buying energy saving light bulbs can be more complicated than you think. If you go into any supermarket or DIY shop you can buy energy saving bulbs for a few pounds. In general these do not function very well. For example, they don't last very long, they give off a dim yellowish glow or take quite a long time to come on. These problems that are associated with energy saving bulbs are completely avoidable if you know what you are buying and the inormation here will help you make an informed decision and buying a good quality replacement bulb will remove these problems and work out cheaper in the long run as they last so much longer. The environment As well as each lamp using the equivalent of 80% less energy. We endeavor to use renewable or recyclable materials.
We comply with environmental legislations and industry codes of practice.
As the technology improves so the lamps become
smaller, thus using less materials. Terminology Average Life Time It is the duration over which 50% of a large number of identical units are expected to expire when operated under a given strictly controlled condition. Memolux lamps are guaranteed for 10,000 hours. Colour Rendering Index (Ra) It is the measure of how the coloured objects would appear compared to their appearance under a reference lamp at the same temperature. Memolux have an Ra of 80. The scale of the index is 1-100, the higher the index the more accurate the colour. Colour Temperature It is the measure of the colour appearance of the lamps. Item selection is based on personal preference and use. Memolux offer a choice of 2700 (warm white), 4000 (neutral white) & 6500 (daylight). Lumen The lumen is the unit of luminous flux and is defined as the amount of light that falls on one square meter. This will reduce over the life of the lamp. Efficacy—Lumen per watt The light output in lumens produced by a source for each watt of electrical power supplied to the source. Lumen Maintenance 2000 hours
It means the luminous flux of a lamp at 2000 hours in the rated average life of a lamp, including the initial operating hours, divided by the initial value of the luminous flux of the lamp and expressed as a percentage of the initial luminous flux. General Specification Lighting Time: ≤0.4 second
