Leveraging Lighting - Increasing Your Bottom Line while Enlightening the Environment

Who Are We? Located in Grand Haven, MI, Light Corporation has been enlightening the world s workspace since 1986. While our business started with designing and manufacturing lighting for the office furniture industry, we ve grown into other avenues of workspace lighting. Our goal is to enlighten the workplace everywhere people work.

Who Are We? We re proud of our environmental record. We re committed to conducting all aspects of our business in an environmentally friendly manner. We re a member of the U.S. Green Building Council and a Michigan Clean Corporate Citizen.

Introducing - Semaphore We ve recently introduced our Semaphore Series of lighting fixtures. A patented design, Semaphore was designed for use in the industrial, warehouse, gymnasium, and retail applications.

Semaphore - Characteristics Semaphore features an aluminum exoskeleton TM form-factor designed for its clean aesthetics and lightweight manageability.

Semaphore - Characteristics Semaphore utilizes a patented modular specular reflector, designed for even and focused light dispersion.

Semaphore - Characteristics Rounding out the fixture is Light s own Slip-Fit TM hanging system that allows for ease of installation in 1/3 of the time it takes to hang standard fixtures.

The Semaphore Series The Semaphore Series of lighting fixtures were created utilizing the design influence of high-end architectural lighting blended with a high-output, low-power consumption lamp and ballast combination to create a true balance between form and function.
