Keystone’s innovative Future Fit LED kits are the ideal solution to convert legacy fixtures into energy-efficient LED systems. Keystone pre-packages the appropriate Keystone drivers, modules and mounting accessories which means that the LED retrofit can be installed quickly and easily either in the field or at the point of fixture manufacture. We did all the safety testing and performance verification, so upgrading to LED is as easy as zip-screwing in these clever Future Fit LED kits, only from Keystone.
