Some Samsung Electronics Co., Ltd. TVs appear to consume more energy during real-world use than during official lab testing conditions, The Guardian of the UK reported Oct. 1, citing independent tests.
Official Tests vs. Real World
According to Samsung, the so-called “motion lighting” feature of its TVs reduces power consumption by reducing screen brightness in response to types of content. However, the feature only appears to function under official test conditions.
The Letter and Spirit of The Law
“The lab studies found that Samsung’s ‘motion lighting’ feature reduced the TV sets’ brightness – and power consumption – under international electrotechnical commission (IEC) test conditions, the paper said. “But under real-world viewing conditions, no reductions in power consumption were registered, making the sets’ power consumption, fuel bills and carbon emissions correspondingly higher.”
“Samsung is meeting the letter of the law but not the spirit of the law,” The Guardian quoted Rudolf Heinz, a project manager with ComplianTV, as saying.
Samsung’s Volkswagen Moment?
“The apparent discrepancy between real-world and test performance of the TVs is reminiscent of the VW scandal that originated in the US last week,”. The Guardian added.
Samsung has denied it is cheating EU compliance tests, claiming that the “motion-lightning” software is a standard “out-of-the-box” feature used on all its TVs. “Motion lighting is not a setting that only activates during compliance testing. On the contrary, it is a default setting which works both in the lab and at home; delivering energy savings and helping us to reduce our environmental impact,” the company said in a blog post.
