The ability to control fire is considered one of the most important factors in expanding and developing our human ancestors’ societies. The societal importance of fire required larger and larger groups to work together in order to maintain and sustain the fire; individuals had to work together to find fuel for the fire, maintain the fire, and complete other necessary tasks. Ultimately, fire had a significant influence on the development of language and the size and social interactions of communities.
The Forum for Illumination Research, Engineering, and Science (FIRES) is the IES online space for our lighting community to openly share and discuss the latest research and innovations in illumination engineering and science. As a space for the free dissemination of knowledge and exchange of ideas, FIRES is intended to foster relationships between individuals and larger institutions, and reignite the emphasis on science and engineering in the lighting industry. Through FIRES, we hope to have a significant influence on the development and advancement of lighting.
The views expressed in articles published on FIRES do not necessarily reflect those of IES or represent endorsement by the IES.

Written in 2015, “Greenhouse Design and Control” (Ponce et al. 2015) is extraordinarily comprehensive in its coverage of greenhouse design issues, from site selection through structural load bearing analysis and ventilation technologies to greenhouse automation using adaptive neural fuzzy inference systems. On the topic of greenhouse lighting, however, it has only this to say: “The light level in the greenhouse should be adequate and uniform for crop growth.”
Around 20 years ago, a new type of cell was discovered in the human retina, the fine layer of tissue at the back of our eyes that enables us to see the world in its colourful detail. These cells, the intrinsically photosensitive retinal ganglion cells (ipRGCs), are sensitive to light independent of the canonical photoreceptors, the cones and the rods.
