'Why are a far cry from what the price of different brand?
because of the price of energy-saving lamp because of its technical content and components cost and each are not identical. Philips electronic energy-saving lamps, for example the smoked it using the real three colors of rare earth phosphor powder, and some other brands use compared to ordinary fluorescent powder/three primary colors of phosphor, it's on to ensure long life at the same time, also can always maintain high brightness, high performance/price ratio, and the actual product. Accordingly, when the choose and buy energy-saving lamps to comprehensively consider the initial purchase cost, use cost, replacement cost and use effect and so on various factors.
when why buy energy-saving light is very bright, but the in the dark?
normal energy-saving lamps in use after a period of time, as the wastage of the phosphor powder, will be more in the dark, technically called droop. Droop is one of the important measure of energy-saving lamps quality, high-quality energy-saving lamps to ensure minimal droop in use process happen. Such as philips invented in longevity type energy-saving lamps in the constant light technology, can let the lamp which can keep the best working state, use after 2000 hours, light failure is less than 10%.
'the effect of energy-saving lamps will be affected by the temperature?
25 degrees usually are the best working temperature in energy-saving lamps. In the process of practical application, the influence of environment temperature and energy-saving work, its heat will make this the best working temperature can not be achieved, which affect the energy-saving lamp brightness. In order to solve this problem, philips's new permanent bright design for energy-saving lamps even on this big - 20 to 55 degrees Celsius in the temperature span can achieve normal ignition point.
low energy-saving lamps are white light?
no, energy-saving lamps are warm and cool colors. The warm light of high quality energy-saving lamp design and excellent color rendering technology, make its light color the same as the ordinary incandescent lamp, light color and pleasing to the eye and comfortable at the same time, let a person really have sweet atmosphere.
