Keystone 4' 120V Dimmable LED T8 Tube - Bypass Ballast
Keystone's new glass coated LED T8 tubes are the new standard in the LED T8 market, as they have the shatterproof aspect of the old aluminum construction combined with the benefit of the wider beam angle of the old glass design. They are also one of the first viable dimming options for an LED T8, as they are dimmable via TRIAC dimmers (Forward Phase Control). Dimmer compatibility list below.
