All three share the same 10 cm low profile — only diameter and LED power differ:

Compact 35 cm / 18 W: hallways, entryways, small bedrooms, walk-in closets, accent placements.
Standard 44 cm / 24 W: standard bedrooms, dining areas, mid-sized rooms.
Large 50 cm / 36 W: living rooms, master bedrooms, larger spaces.

For ceiling fixtures, a useful rule: add the room's length and width in feet, then convert to inches — that's roughly the right diameter. (e.g. 12' × 14' room = 26" diameter ≈ Standard.)

Integrated LED means the light source is built directly into the fixture — no bulb to insert, no socket exposed, no light source to replace under normal use. Modern integrated LEDs are rated for 30,000–50,000 hours (roughly 25–40 years at 3 hours/day). Test the fixture during the return window to confirm satisfactory operation — non-replaceable under normal warranty terms.

The acrylic dome contains fine glittery inclusions cast into the material. When the lamp is off, the dome reads as a soft white surface with subtle texture. When the lamp is on, the inclusions catch and refract the LED light, creating gentle starry sparkles across the dome — the effect is subtle and atmospheric, not flashy.

Hardwired flush mount — connects to a standard ceiling junction box. The wood-frame mounting plate attaches to the J-box, and the acrylic dome clips into place over it. Professional electrician recommended.
