The comparative study of the use of LED lamps ASTZ DVO 04-36-001 PRS instead of luminescent ASTZ T8 LVO09-4x18-011 RS in the engineering room was carried out. Calculation of light distribution and 3D rendering using fictitious colors in both lighting options was done. When using LED lamps, the power consumption is more than 2 times less, the illumination in the working area of the room is more uniform than when using fluorescent lamps. The payback period for LED lamps due to energy savings is 3.7 years. Key words: Fluorescent light, LED light, energy saving, illumination, 3D visualization, fictitious color.
