Warm dimming, explainedMost LED fixtures only get dimmer when you turn them down; their colour stays the same. The ATF7509-DTW is different: its integrated driver dims the light to a warmer colour temperature when used with TRIAC / ELV dimming controls, gliding from 2750 K toward 2000 K, much like a traditional halogen lamp. That makes this
dim-to-warm track head perfect for spaces that switch from work to relaxation: a kitchen that becomes a dining room, a hotel lobby at night, a restaurant as dinner service begins. This version, LCTL-ATF8.5-DTW-WH, pairs the effect with a white finish and a
38° beam angle.
Built to last, made to aimConstructed of aluminum, the body has an aesthetically pleasing smooth cylindrical shape, and a colour matching
aluminum heat sink provides maximum heat dissipation to protect the LEDs; lumen maintenance is rated at 70% at 50,000 hours, and the rated life is 35,000 hours. The head is adjustable up to 90° tilt and 330° rotation, so you can spotlight in multiple directions from a single run of track. The high powered 8.5W chip produces a typical luminous flux up to 532 lumens, or 62.6 lumens per watt, with a
CRI of 90. The series is also offered with 15° and 60° beams, and the photometric report on the spec sheet covers this 38° version.
Electrical and installation detailsThe fixture uses a 120V AC primary voltage and is
dimmable with TRIAC or ELV dimmers; the spec sheet recommends confirming dimmer compatibility, so choose your control before installing. It comes fitted with a track connector, and the ordering guide lists the connector styles offered for the series: make sure yours matches your
track system. It is approved for dry, indoor locations, carries cETLus certification and has been tested to LM79. Always switch off the breaker before adding or moving heads, and have a qualified electrician install the track and its power feed.

Ideas and documentationUse a row of these
track light heads to wash a white brick wall in a loft, highlight the headboard wall of a hotel room, light the pastry case of a café or pick out family photos along a hallway, then dim everything down to a warm glow at night. For a room with a dark ceiling, the
7509 dim-to-warm spotlight in black keeps the same light. The
spec sheet, with technical drawing, ordering guide and photometric report, is available in the Documentation tab.
