Thats kind of an oxymoron since infrared isn't a visible part of the spectrum. http://www.antonine-education.co.uk/...m_spectrum.jpg
A true infrared just puts off heat. no visible light whatsoever (unless you've got very specific cut off filters that will allow inferred to pass through).
The red bulbs aren't infrared, they're just regular light bulbs with red coating on them.
