An lightwave oven and method of cooking therewith for cooking food with radiant energy in the visible, near-visible and infrared ranges of the electromagnetic spectrum from a first plurality of high power lamps positioned above the food and a second plurality of high power lamps positioned below the food. The first plurality of lamps are sequentially operated at a first average power level by applying power thereto in a staggered manner so that not all of the first plurality of lamps are on at the same time, and the second plurality of lamps are sequentially operated at a second average power level by applying power thereto in a staggered manner so that not all of the second plurality of lamps are on at the same time. The stagger can be varied to change the time average power level of the first and/or second pluralities of lamps without adversely affecting the spectral outputs thereof. The first and second pluralities of lamps can be operated in one of several different modes. In one mode, the first and second pluralities of lamps are sequentially operated simultaneously. In another mode, the first plurality of lamps is sequentially operated while the second plurality of lamps are turned off. In yet another mode, the second plurality of lamps is sequentially operated while the first plurality of lamps are turned off.

[ What is claimed is:] [1.] A method of cooking food in a lightwave oven having a cooking region and a first plurality of high power lamps positioned above the cooking region and a second plurality of high power lamps positioned below the cooking region providing radiant energy in the electromagnetic spectrum including the infrared, near-visible and visible ranges, comprising the steps of:sequentially operating one of the first and second pluralities of lamps at a first average power level by applying power thereto in a staggered manner so that not all of the lamps of the one plurality of lamps are on at the same time; andsequentially operating the other one of the first and second pluralities of lamps at a second average power level by applying power thereto in a staggered manner so that not all of the lamps of the other one plurality of lamps are on at the same time;wherein for at least a predetermined time, the sequential operations of the first and second pluralities of lamps are not performed simultaneously, so that the first plurality of lamps are turned off during the sequential operation of the second plurality of lamps, and the second plurality of lamps are turned off during the sequential operation of the first plurality of lamps.
