Built for aiming, built to lastThe ASTELLA Series track head is a compact cylinder on a rotating yoke and adapter, so you can swing the head around the track axis and tilt it to land the beam on a shelf, a canvas, a counter or a reception desk. The 35W version is the largest of the family at a Ø90 mm (3.54 in) head and 216 mm (8.5 in) overall dimension, giving the LED and its heat sink room to breathe. The black finish keeps the fixture visually quiet against dark ceilings and exposed structure, while the adapter locks into the track with a spring-loaded locking tab and a simple quarter-turn.
Light quality and colour selectionWith
CRI90+, this head renders colour far more faithfully than a typical builder-grade spot — a genuine advantage anywhere merchandise, art, food or people are on display. The
5CCT feature gives you five selectable colour temperatures through a small colour-select switch located on the back side of the track head, so you set the ambience after the heads are up and the room is furnished. Combined with
TRIAC dimming, you can drop the level for evening service in a restaurant or raise it for a weekend retail rush, all from a standard forward or reverse-phase wall dimmer.

Electrical work and installationInstallation follows the printed instruction sheet: cut power at the breaker or remove the fuse — a wall switch alone is not enough — then attach the mount plate to the J-box and connect black to hot, white to neutral and green to ground. Tuck the wires into the box, mark and drill for the toggle bolts, set the track channel onto the mounting plate, tighten the toggle bolts and the two mount plate screws, then install the connection terminal respecting the single-pin and double-pin orientation and slide the canopy cover over the J-box. For the head itself, hold the adapter with your thumb on the locking tab, align the tab directly opposite the polarity line (the arrows on the tab point to it), push the adapter into the track and rotate a quarter turn (90°) counter-clockwise. Safety rules from the manufacturer: indoor only — never damp or wet locations — never less than 5 feet above the floor, never within 6 inches of curtains or combustible material, never more than one branch circuit unless the track is built for it, and nothing but track luminaires on the track. The housing gets hot: wait at least 5 minutes after power off before touching it.
Compatibility, applications and documentsThis head is designed for
single-circuit J-type track, ceiling mounted only. Mix wattages on one run for a layered scheme — the
10W black head for small accents, the
20W black head for general highlighting, and the
20W white head or
35W white head when the ceiling calls for white hardware. Typical projects: a clothing boutique aiming heads at each rack, a café highlighting the pastry case, an architect's office grazing a brick wall, a home gallery corridor, or a kitchen renovation where one track replaces a row of pot lights.
