„ Ra 78 Approx
for measuring a lamp's visual output. The metric is a
number ranging from 0 to 100 that is used to determine
how well a lamp reproduces colour. Colours should
appear more true or authentic in the light as the figure
approaches 100. CRI is calculated by comparing a light
source's ability to render eight different pastel hues. A

light should theoretically be able to produce all colours
if it can describe these eight colours well. 80 CRI (Ra) is
the common baseline for good colour rendering for the
majority of commercial lighting. For applications where
colour appearance is important for the work being done
inside, or can contribute to improved aesthetics, 90 CRI

LOCKS

Although both LUX and Lumen are units of measurement for light, they describe light output in very different ways:
Lumen (lm): lumens indicate the amount of light emitted LUX (lx): lux indicates the intensity of light on a given
STEPS
by a source. Imagine it like a light bulb's overall brightness. surface at a specific distance.
For instance, a bulb with 800 lumens is brighter than one
with 400 lumens.
In conclusion, Lux indicates the precise brightness of a light at a distance, such as one meter, whereas lumens tell you
how bright a LED or fixture is, it doesn’t tell how effective the light is at range.
