The lamps will flicker or refuse to start at low settings. Swapping a whole run to LED often means changing the dimmer as well, and that is worth budgeting for before you start.\u003c\/p\u003e\n\n\u003ch3\u003eFrosted or clear\u003c\/h3\u003e\n\u003cp\u003eFrosted glass softens the edge of the beam and hides the emitter, which matters in a fixture you look up into. Clear gives a tighter beam and a visible source. For a track head aimed at artwork, clear. For a ceiling fitting in a living room, frosted.\u003c\/p\u003e\n\n\u003ch2\u003eRelated\u003c\/h2\u003e\n\u003cp\u003eFor the fixtures these go into see our \u003ca href=\"\/collections\/track-lighting\"\u003etrack lighting\u003c\/a\u003e.
