I have a fairly robust work table with a Rhino mat / grid on it. The top is made from 1 1/2 of MDF. My plan is to drill holes through the table in a grid pattern and install LED's so that I can light up the whole thing. The Rhino mat would act as a diffuser to help distribute the light. I considered cutting a portion out and putting a glass top with light box but this table is used for many things that would damage the glass. The LEDs would require 1/4" holes and would be mounted just below the surface so there is not concern for breaking anything. Has anyone done something similar and can share the optimal spread on the LED's?
