Jan 25, 2016: LED manufacturers have been making tall claims of LEDs standing at 50000 hours but the real test lies in standing with the reputation as promised by LED light manufacturers.
In a reality check, LED lighting warranty is one parameter as initial few years comprise to less than 20% of the total working hours. The real test lies in after the warranty period is over or if you are a consistent commercial user.
We do not always get what is considered. Here, we will guide you on the aspects, essential while choosing high and low quality LED lights
A very important aspect is weight of the LED light. As LED lights require good heat dispassion, a good amount of aluminium is needed and that can only be accomplished with heavy LEDs. Some china based producers provide 12-20W lights in very low weight that feels like plastic body. These products won?t perform well even in small span of time. Thin sheets can provide more area in less weight, but it can?t transfer enough heat for the removal. Only active (fan based) cooling provides solution to this.
LED chips are manufactured all over the world with Japan and USA based suppliers make highest quality for longer life and more reliability. Quality relies on the materials used in making chip. Larger chip provide more light and stability against current variations but it costs more. Cheap and small led chip provides less light and stability.
Consistent power supply is as important as the Led itself. LEDs are kind of semiconductor that needs to be driven with care and as per ratings. A constant current DC supply for longer life is needed for LEDs.
Rare earth phosphor is another costly thing in LED lights. Manufacturers often use low quality phosphor to lower the cost and if you see spot light with little different white colors, it is a sign of low quality. Maintaining same colors in white is challenging task for LED producers as Color rendering is also point to be considered. For good LED lights, high quality phosphor for high CRI is required.
LED lights have become a new trend in interiors. Low quality LED lights have same optics for multiple requirements. A spot light cannot make enough light in drawing room. Used to hide low quality components in lights, opaque cover is not always for good lighting.
The ?make? is the most important feature as it covers all ie; design, look, feel and strength need to be checked at time of choosing LED. The paint or powder coating has to be of superior quality to ensure inside construction is also better.
