The Math

By converting your existing fluorescent lamps with Kowa LED tubes, one may able to create an average 53-watt saving per fixture (assuming a standard fixture with three 4 ft. T8 fluorescent lamps consumes 88 W). This switch may save about 233 kilowatt hours (kWh) of electricity a year - approximately a $25.60 utility cost reduction (based on an $0.11 kWh and 4,400 hours of operation). One may also anticipate less maintenance: a user of fixtures with fluorescent lamps may end up replacing old lamps and ballasts each year.

KOWA Type B ballast bypass retrofits are
the smart way to switch to LED

The most active lights deserve the most efficient product on the market. Kowa is designed to maximize return on investment and minimize payback time. We use the highest grade components and our proven methods of Japanese production management in order to deliver the world’s top level of reliability and quality.

Don’t go half-way and use a “type A” LED lamp!

Eliminate the need for ballasts altogether and simplify your fixture maintenance forever.

Improper ballast and LED coupling greatly reduces the service life of all LED tubes.

KOWA components are designed to work together, maximizing lamp life and lumen maintenance.

New fixtures may seem like a good idea now, but…

Virtually all of the LED fixtures currently on the market are not serviceable, meaning they are designed to be thrown away and replaced after their expected life cycle has elapsed (typically 5yrs / 50,000 hrs.)

Using a modular solution such as Kowa LED “type B” lamps guarantees that your fixtures won’t need to be replaced until you want to do so.
