There are lots of illuminated dog collars that have weak test results are defective or simply impractical. The experienced dog owners of German manufacturer ´die leuchten´ decided to develop a product that would truly improve the safety of dog & owner the LED ring collars. 5 Superflux LEDs in this collar give the necessary light. Other than with round LEDs these lights are square distributing the light more widely & giving brighter light. At night the rings are visible from up to 500 m distance making your dog easily visible to everyone. Durability is also increased to Approx. 100000 hours! Environmental influences such as rain or cold temperature won´t impair this product it´s 100% watertight & the material won´t lose it´s flexibility even in the cold. Simply put the ring loosely around your dog´s neck & connect the two ends. The ring will illuminate straight away. One battery load lasts about 30 hours. Finding your size The ring should be loose around the neck but tight enough not to fall off over your dog´s head. In order to find the right size for your dog measure your dog´s neck circumference & add 10%. Now round up to the next size. Example Dog´s neck circumference = 40 cm plus 10% (4 cm) = 44 cm. The right size in this case is 45 cm.
