Clean form. Controlled focus.
ACME Straight Adjustable is a family of architectural adjustable baffle downlights designed for precise beam control and a calm ceiling aesthetic. Its straight-edged form delivers crisp, controlled illumination for premium residential, hospitality, retail, and commercial interiors.
There are three ACME downlight styles; Curve is ideal for softer, more subtle lighting which integrates into the ceiling finish, Straight is best for a cleaner architectural look and more defined focus — perfect for accent lighting, feature walls, and displays, and Semi for a more expressed semi-recessed form which is enhanced further with Curated Finishes.
