As one of the most widely used devices, the led downlight is playing a very important role in our daily lives, it is always instal LED in a cavity of the top ceiling. There are many kinds of LED downlight for the users to choose, and they may be dazzLED .Then how to choose an appropriate led downlight according to your own condition? Are there any suggestions for the users? Certainly! Now, let me give you some useful advices about choosing a suitable led downlight.
Generally speaking, if we use the term energy saving to describe a light, it must be the light which consumes less wattage when maintaining the similar luminance. For instance, a standard halogen downlight usually consume 55 watts, and if you want to get the same luminance which the halogen downlight gives out, you only need to buy a LED one of 4.5 watts. Averagely, if the light uses higher wattage, it will have higher light output. Then you may ask: how many watts do you need? When choosing the LED downlight, you should not only take the wattage into consideration, that is not enough, other influence factors should also be considered, and these influence factors are usually related with the area which needs to be illuminated.
We always use the indicator calLED lumen to measure the luminance of a light. Let me give you a simple example about lumen, if we ignite a candle, then the total flux of the radius semi diameter range of 0.28 meters with the ignited candle as its axle center is equal to 1 lumen. Generally speaking, higher lumens result in brighter light.
3) Beam spread
We always use the term calLED beam spread to measure the angle of light from the luminous source. The height of the general ceiling is usually between 2.4 and 2.7 meters, in this condition, I recommend a wider beam spread over 60 degrees. And if higher than 2.7 meters, the angle of less than 50 degrees is recommended.
4) Warm white and cool white
Choose what color of the LED downlight, warm white or cool white? It only has something to do with your own preference, but if you can choose a suitable color according to your own condition, you may get a better result, I think that I can give you some suggestions about this, for the areas in which you want to fufill a task, for instance, kitchens, laundries and the like, the color of cool white is a decent choice, be different from the cool white, the color of warm white can create an easeful atmosphere, and it is suitable to bedrooms, living rooms, studying rooms and the like. And please remember, use only one color in an open area, or you may be distracted by the mixture of colors, as time passes, your eyes may be ill.
