An LED will generate photons when connected to a noisy resistor. An LED will generate photons at *any* voltage level, below forward voltage, even though LED's are far more efficient at the forward voltage. Furthermore, there's no upper crest voltage limit to thermal noise. That is "free energy," but an infinitesimal amount. It is possible to fit billions of such LED's and R's in a small area, which would generate a significant amount of light. Also note that voltage noise from composite resistors increases with a decrease in size; e.g., a 1 micron 1 Gohm R generates more noise than a 1 inch 1 Gohm R.
