    Exemplary Service

    I must confess, I seldom take the time to respond to these types of inquiries, I simply do not have the time to spare.  However, the level of service I received from your staff helping to rectify an issue with one of your shipments was truly exemplary.  I would highly recommend your company to anyone with lighting needs.  It has been a pleasure to work with your firm.
