Rich lineup with 141 models*

We have a lineup of 141 models*, such as combinations of the size and emitting width of the emitting surface, directional characteristics, and the emitted color.

* Total number of models of the conventional products and high-power type products.

Compatible with a wide range of uses

You can freely adjust the illuminating direction and angle for use in a wide range of uses.
Because Bar Lights can freely adjust their illuminating direction and angle to match the workpiece, they can provide the optimal image.

Increased brightness and rich variety of sizes

Directional characteristics

Model name

Conventional product High-power type

Power consumption values are different between the conventional products and high-power type products. Before use, make sure that the total power consumption of the Light Units is within the output power capacity of the Control Unit. Optional accessories are applicable to the new products as well as to the conventional products of the same size. For details on the optional accessories that are applicable to the Light Units with the newly added size, refer to the lineup tables under "Options."

Bar Lights that use surface-mounted LEDs

These are Bar Lights that use surface-mounted LEDs.
We provide the narrow type, which performs convergent illumination for a narrow space, and the wide type ( -WD) which illuminates a wide space.

Select the directional characteristics of a narrow type or wide type

Example configuration

Achieved light with a narrow directionality using the original lens located in front of the LEDs. Illuminates direct light from any angle.

Change to White LED Models

Discontinued models and successor models

Applicable Models

LDL2 Series white LED lights (all models)
Ex. LDL2-19X4SW2 -> LDL2-19X4SW2(A)

Impact on Function and Performance

New white LEDs have been used in the successor models.
The correlated color temperature is lower and the color is yellowish-white.
