Choose a bulb according to luminous flux and CRI value

The luminous flux has a key influence on the choice of LED bulb, as it determines the level of illumination in a given space. The higher the luminous flux, the more light the bulb emits. This parameter usually ranges from the low hundreds, such as 200 lm, to the lower thousands, such as 2,500 lm. The luminous flux of the offered LED bulb OSRAM is 270 lm. The Colour Rendering Index (CRI) assesses the ability of a light source to faithfully represent the colours of illuminated objects compared to natural light. The CRI is expressed as a numerical value from 0 to 100, with a higher number indicating greater accuracy in colour representation. OSRAM LED bulb brings CRI.
