Nikki NLUD Series Surface-Emitting LED Light
Manufacturer: Nikki Co., Ltd.
Model: NLUD Series
Features
This is a surface-emitting LED light with dimming function. The light output can be adjusted continuously from 20% to 100% using the touch sensor built into the main unit.
The illuminance memory function ensures that the brightness level from the last time the light was turned off is restored when the light is turned on again. (The illuminance memory is reset when the light is unplugged.)
It produces a natural light without the glare that is typical of LEDs, and is free of flicker and unevenness.
Since shadows are less likely to form, you can see what you want to see clearly without stress.
Dimming function
Dimmer switch (left): You can adjust the brightness to any value between 20% and 100%.
Power switch (right): You can turn the light on and off with just a light touch.

Comparison example between conventional LED and our NLUD
When illuminated with a conventional LED (left), shadows are cast, but with NLUD (right), shadows are less likely to be cast.

Color rendering index (Ra)
Color rendering is an index that indicates how faithfully a light source can reproduce the color of an object illuminated by the light source.
High color rendering allows you to produce natural color reproduction similar to that seen under sunlight.
If the color looks exactly the same as when viewed in natural light, the score is 100, and as the difference increases the score decreases.
Light sources with high color rendering are suitable for applications such as painting and finish inspection, where color must be seen.
Special color rendering index R1 to R15
Average color rendering index (Ra)
Average color rendering index of 8 test colors (No.1 to No.8)
Special color rendering index (Ri)
In addition to the average color rendering index Ra, it also indicates the evaluation of familiar and important colors such as red (No. 9), yellow (No. 10), green (No. 11), blue (No. 12), Western skin color (No. 13), leaf color (No. 14), and Japanese skin color (No. 15).
Comparison with conventional products (Ra80 5700K)
Compared to conventional products, the Ra95 5000K specification has an average color rendering index of 97.3, allowing accurate color reproduction even in environments where faithful color reproduction is required.
NLUD20-AC (Ra80 5700K specification)
There is a small amount of color and each color is different.
NLUD20-AC (Ra95 5000K specification)
There is a large amount of color and little difference between each color
