And yes, these are complete fakes. The glass plate looks like an amorphous silicon solar cell module and even shows the typical brown lacquer finish on the backside, however it lacks all electrical contacts. Inside the plastic body there is a circuit board connecting the three white LEDs to a heat-shrinked soldered pack of two non-rechargeable CR2016 batteries. Current limitation to the three LEDs in parallel connection is only by means of the internal series resistance of the batteries.<\/p>\n<p><figure id=\"attachment_1957\" aria-describedby=\"caption-attachment-1957\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1957\" src=\"http:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000-300x135.jpg\" alt=\"inside a &quot;solar powered LED flash light&quot; without any solar power\" width=\"300\" height=\"135\" srcset=\"https:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000-300x135.jpg 300w, https:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000-1024x460.jpg 1024w, https:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000-150x67.jpg 150w, https:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000-400x180.jpg 400w, https:\/\/www.sciencetronics.com\/greenphotons\/wp-content\/uploads\/2017\/03\/IMGP3705a_1000.jpg 1132w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-1957\" class=\"wp-caption-text\">inside a &#8220;solar powered LED flash light&#8221; without any solar power<\/figcaption><\/figure><!--more--><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inspired by a Youtube video from Bigclive I ordered some Solar Power Rechargeable Flash lights.
