Choose a bulb according to luminous flux and CRI parameters

When choosing an LED bulb, you must take into account its luminous flux, as it defines how strong the lighting will be in the room. Higher luminous flux values mean more intense illumination. This parameter typically 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 OSRAMis 140 lm. CRI, or colour Rendering Index, is a measure of the ability of a light source to faithfully reproduce the colours of illuminated objects compared to natural light. The CRI value is a number between 0 and 100, with a higher value indicating a better ability to display natural colours. The OSRAM LED bulb delivers a CRI of 80 Ra.
