I am trying to run a meta_query with an array of values and have it search if all are present in the meta value which is stored in a serialized array. Is this possible?

My arguments for the query is as follows (note that this is nested in a class):

$args = array(
    'post_type' => $this->posttype,
    'posts_per_page' => '9',
    'paged' => $paged,
    'orderby' => 'meta_value_num',
    'order' => 'DESC',
    'meta_key' => 'lumens',
    'meta_query' => array(
            'key' => 'mount',
            'value' => array('pendant' , 'wall'),
            'compare' => 'IN'


An example of the meta data stored, is in a serialized array similar to below:


My query will not return the appropriate results no matter what I try. I am realizing now that I probably should have stored each value in a different meta-key rather then in an array, however, there is far to many entries already to change the metadata now.
