Made to order


If a common modification cannot solve your lighting challenge, then inquire about our efficient 'made to order' solutions.  We have over five decades of experience customizing fixtures to meet specific projects needs. One of our many custom projects includes Yale's Sterling Memorial Library (pictured below), for which we designed custom PAR38 LED fixtures. Learn more about the project here.


The Modification Process

From first inquiry to final delivery, our Technical Sales team we will guide you through our efficient 5-step modifications process. 


Step 1

Upon receiving the initial request, we will research the modification, including previous experience, potential heat tests, required components and tooling, and supplier feedback.


Our Technical Sales team: Linda, Holly, and Dan


Step 2

Our Technical Sales department will provide a quote, if the modification is confirmed feasible.


Step 3

Upon receiving a purchase order, our engineers may either: a) confirm a prototype is unnecessary, and create master assembly drawings, or b) confirm a prototype is necessary and design a custom fixture. If a prototype is created, our Metrology department will perform in-house heat and pull testing.

Step 4

Once the drawings have been approved, and the order has been released, our team will create detailed parts drawings and finalize the factory's bill of material.


Step 5

Working closely with the engineers, our manufacturing employees will begin fabrication.
