Recommendation for Photon Panel Grow Light Panel heat rise when mounting to a wooden shelving unit.

The installation guide for PN: 2020 mentions the heat rise in the open air and also mentions mounting it to a wooden shelving unit. I'm considering doing it, but I'm worried about the heat if mounted directly to a wood shelf. Is this something that is supported/recommended?

Unfortunately, we do not have any additional data on the temperature rise when mounted to a solid surface, however, we would expect that the thermal rise would be within a similar range.

Depending on the material of the wood shelf, such as the varnish or coating, the heat generated may or may not be a concern. We would recommend performing a test to make sure that the temperature rises in your particular installation stay within reasonable levels.
