Keystone provides a wealth of LED T8 offerings and they have expanded their repertoire further with their Type C External Drive LED T8 lamps. Type C LED T8 lamps are powered by an LED driver, similar to how an Instant Start ballast powers fluorescent lamps. Keystone offers 2-lamp and 4-lamp LED drivers that are designed specifically to operate their own External Drive LED Tubes. These LED drivers can be paired with a 0-10 volt dimmer to allow for crisp low voltage dimming with the External Drive LED tubes.
