SHADA BV LED Water Proof Armature
DLG-APPROVED "Resistance to ammonia"
A test mark „DLG-APPROVED for individual criteria“ is awarded for agricultural products which have successfully fulfilled a scope-reduced usability testing conducted by DLG according to independent and recognized evaluation criteria. The test is intended to highlight particular innovations and key criteria of the test object. The test may contain criteria from the DLG test scope for overall tests, or focus on other valuedetermining characteristics and properties of the test subject. The minimum requirements, test conditions and procedures as well as the evaluation bases of the test results will be specified in consultation with an expert group of DLG. They correspond to the recognized rules of technology, as well as scientific and agricultural knowledge and requirements. The successful testing is concluded with the publication of a test report, as well as the awarding of the test mark which is valid for five years from the date of awarding.
The ammonia resistance test was performed as a laboratory test according to the patented DLG test standard. This test is intended to determine the suitability of equipment for animal living areas to withstand the impacts of animal environments. The cleaning distance test assesses the suitability for cleaning animal living areas. Other criteria were not tested. As of 2017 the luminaires will be operated in the test chamber both passively (without power supply) as well as actively according to a determined test program.
Assessment – Brief Summary
The luminaire “LED Water Proof Armature” has successfully completed the DLG test for ammonia resistance. According to this result, it can be assumed that these luminaires are resistant to the typical environmental conditions of animal living areas and that no accelerated reduction of the product lifetime will occur. In addition, the luminaire “LED Water Proof Armature” was operated actively in the chamber for the entirety of the test. No product damage was observed here.

The Method
Resistance to ammonia
The ammonia resistance of the LED light “Patron LED tri-proof light” was determined by a laboratory test with one luminaire according to the patented DLG test standard for agricultural use. The laboratory test is designed to replicate the conditions of a usage period of about 10 years exposure to animal living areas.
The test was carried out in a climate chamber under the following climate conditions:
For assessing the ammonia resistance, each luminaire was examined visually, gravimetrically and the plastic parts additionally through measurement of the hardness (Shore D) before and after the climate testing. Since 2017, luminaires have additionally been following a cycle of operation predefined by DLG (3 hours on, 1 hour off) in order to eveluate any thermal impacts caused by switch-on and -off procedures during ammonia fumigation.
In order to avoid overheating (> 70 °C), the luminaires could be operated at a reduced power level during the testing period.
The Test Results in Detail
Resistance to ammonia
Visual test
The comparative visual examination after the ammonia exposure has shown minor discolorations at the inside of the luminaire housing. There were few discolorations on the outside of the housing. The deformation at the housing kept within limits. Due to the high temperature during the DLG test the end cap of one luminaire became detached.
It cannot be ruled out that a limited ammount of ammonium compounds might enter the luminaire housing. Also in this case, no negative impact on the luminaire performance needs to be expected. The defects are rated as insignificant.
The examination of the mounting parts provided by the manufacturer didn’t show any defects.
Gravimetric test
Weight comparisions before and after the ammonia fumigation have not shown any measurable increases or decreases in weight.
Hardness test
During the hardness test (Shore D) no measurable changes were observed. All determined changes were within the measurement incertainty.
Functional test
No defects were observed. All luminaires worked well after the conducted tests.
Based on the results of these tested parameters, the luminaire is evaluated as resistant to ammonia.
Summary
The results show that the luminaire “LED Water Proof Armature” fulfills the testing requirements for ammonia resistance and thus receives the test mark DLG-Approved. It can be expected that the luminaire is resistant to ammoniacal air in barns and stables and that no accelerated reduction of the product lifetime occurs.
The luminaire “LED Water Proof Armature” was operated both passively and actively during the ammonia fumigation in the test chamber and passed both tests successfully.
Other critera have not been assessed.
