Keystone's defect rate is one of the lowest in the industry – less than 0.1% of all installations. We achieve exceptional results in the field because we are rigorous in our quality control process. For example, every electronic ballast is connected to a lamp for at least one hour to ensure component integrity and circuit reliability. No other ballast manufacturer exceeds our rigid testing regimen.
