Message from the President

Our company started as a lamp production factory of Iwasaki Electric in March 1985.

In addition to the arc tube of high-pressure sodium lamps that has been in operation since the company was founded, we have consistently handled the cutting, cleaning, processing, and heat treatment of quartz tubes, and have expanded our business to include some completed lamps.

Not only for lamp lighting, but also for ultraviolet rays, incorporating in-house produced lamps

We also manufacture UV irradiation equipment.

In the meantime, we will work hard on each and every thing, without cheating, from our customers.

We have earned the trust.

We will continue to be grateful and work with our employees in a positive and sincere manner.

President and CEO Ryo Kosaza
