Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, infrared (IR) heating elements are controllable to emit IR radiation at a peak wavelength in the near infrared (NIR) and/or short wave infrared (SWIR) band(s), and the peak wavelength may be varied by adjusting the voltage applied to the IR heating elements. The peak wavelength may be selected so as to preferentially heat the frit material used to form a VIG edge seal while reducing the amount of heat provided to substrates of the VIG unit. In certain example embodiments, the substrates of the VIG unit do not reach a temperature of 325 degrees C. for more than 1 minute.
