Infrared is typically broken down into three regions, the near, the mid and the far, with the near infrared being the region nearest the visible light
spectrum. Though typically, IR light does not contain sufficient energy to activate the rods in our eyes, there are conditions in which some infrared
light is visible. However, this only occurs when the light is particularly concentrated - i.e. in certain lasers.
Most likely, the lamps are emitting near infrared light and/or light at the border of the visible spectrum. What you're seeing probably isn't IR,
but red light with a wavelength of about 700nm.
