In addition to target life, MTBF (mean time between failures \/ failure-free interval) gives about the probability within which a product will fail within its target life.<\/p>\n<p><em>The project installed 100 LED Drivers that have 10,000 burning hours. Total time = 100*10,000 = 1,000,000 hours. The MTBF is 321,000 hours. This means that on average 3-4 LED Drivers fail under the test conditions. Over the course of a good 4 years, 3-4 defects can be expected to occur. Combined with the standard deviation, it is possible to monitor whether the dropout rate is within expectation.  <\/em><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-091ab0d elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"091ab0d\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-5fc6496\" data-id=\"5fc6496\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-886ee03 elementor-widget elementor-widget-text-editor\" data-id=\"886ee03\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Energy Efficiency: a well-designed LED Driver has good energy efficiency in its power class. This means lower energy consumption and therefore lower costs. Also, energy efficiency says something about the design of the LED Driver. High energy efficiency in the respective power class usually means better design. In addition, higher efficiency promotes longevity because less energy is lost to heat.<\/p>\n<p>Power Factor &amp; THD: the efficiency of the LED Driver in using the electrical energy it absorbs. A high power factor usually means a well-designed LED Driver. The advantage of a high power factor is the favorable capacity load it has on the power grid.
