I would respectfully disagree. Every orifice introduced to a horizontal plane weakens the plane. That weakness is exacerbated as the length to width correlation is increased. Not to mention how the thickness of the plan and the tensile strength of the material contributes.
When drilling the verticle plan of an aquarium (which is must thicker than a glass canopy), it is the strength of the bulkhead that spans the opening and makes up for the loss of structure.
Again, do not drill multiple holes in a sheet of glass and expect it to perform as it did before. Or even close. Especially when the use of that glass is in the horizontal position and relatively thin. You will lose structural integrity, you will see cracks begin to appear spreading from the hole locations and you will eventually have a failure unless some other bridging of the structure is introduced
WOW I never knew that thank you
I was always under the impression that as long as you dont put alot into it hole wise it would be fine , Either way Like kurt said use the legs it also helps to get air circulation around the light
