There must be a lot of preparation work before install led wall washer light ,  it will be helpful for succeed in installing and using ,  so let's find out what preparations need to be made in advance .


                                                                                 


Internal controller or exernal controller need to be confirmed before installation , including the model number of controller .   What kind of lighting effect you wanna get will be operated by the inner editing program of the controller .  There are tricolor gradient , jump , run in full color , pipeline effect , etc .    The display of  defferent lighting effect need to be programmed in thecontroller program .

2. the next step is to wire , there are mainly cables of driver and lamp ,  confirm voltage of controller and lamp again , the lamp's quantity and lamp corresponding to one controller . Generally , controller of led wall washer light has three different products ,  D+,  D-, GND  ,  besides these , do not forget connect ground wire , it will affect directly the safety of using .  The programs of controller must be made well in advance and tested effect  repeatedly ,  it can not be wrong ,  because it is hard to recorrect after installation .  There is also network test , to check signal correct or wrong ,   when above everything is done well , start testing how the preparations are done . Repeated switch electrical shock ,  aging test  , to see if there is  not flashing ,  not bright , special phonomena,etc through test.

3. If above everything  is done well , proceeding  acceptance of led wall washer light , and then poroceed with installation work.  Do not try to save trouble,  you must know , this installation project itself is relatively large ,  if it is involved with post-maintenance , the cost must is definately high .If it is not defected well , it will be unworthy and cost will be high because it is not ready for installation in advance and lead to a maintenance .   It can not be just unilateral problem , but also requires all aspects of maintenance, testing, and specific problems. Anyway, whether you do or not to prepare in advance, if there is no problem, the probability is relatively small. If there is a problem, then It is not something that can be solved at once.
