LED Black Lights for Shadow Box Picture Display

I'm looking to insert an LED black light source into an 11x14 shadow box (around the edges) to display a picture. The 3 concerns I have are heat build-up inside the frame, a clean and neat electrical connection to a power source, and the intensity of the fluorescent display. What would you recommend?

Based on the details provided, we would recommend the 365nm realUV™ LED Strip Lights, as this version of the product can produce the greatest fluorescent effect while emitting the lowest amount of visible light. 

Generally speaking, we can confirm that the LED Strip Lights do not emit a large amount of heat while operating. We have attached a blog post from our website below on the topic, in case it proves to be helpful. 

How Hot Do LED Strips Get? Is It Normal?

For power, we would recommend the 12V FilmGrade™ DC Power Supply for LED Strip. As the LED Strip Light and power supply both use barrel jack adapters, we would not assume that the installation would require additional wiring for power.

We have also attached two LayoutMaps below, which contain configuration layouts, descriptions, and links to the products and optional accessories.
