Technical description
Square recessed downlight performance with fixed and tunable-white choices.
Opti uses Tridonic technology, a die-cast square bezel and a highly specular reflector with 96% efficiency.
Body, bezel and mounting
The 170 × 170 mm bezel sits over a 140 × 140 mm ceiling cut-out. Body height is 112 mm, and the listed ceiling-thickness range is 5–35 mm.
The fitting is supplied with a 500 mm supply lead and includes short-circuit, overload and temperature protection.
Output and colour temperature
Fixed 3000K and 4000K entries span 1,200–3,025 lm. OPTI.000 provides 1,725 lm across a 2700–6500K tunable-white range.
The current datasheet assigns both 2,075 lm and 3,025 lm rows to OPTI.002 and OPTI.004. Confirm the required output when requesting a quotation.
Controls, emergency and decorative accessories
/ECO covers SwitchDIM, DALI or DSI control gear. /BTC provides Casambi Bluetooth wireless control including dimming.
Four emergency suffixes separate standard, DALI and self-test conversions from integral-indicator arrangements. /UB enables the DA001–DA004 decorative bezel accessories.

Why Opti
Why specify Opti?
Opti combines a clean square aperture with Tridonic technology, a 96% specular reflector and fixed or tunable-white colour-temperature choices.
Published output reaches 3,025 lm, with rated life above 50,000 hours and a five-year warranty.
Controls, emergency and bezel options kept explicit
SwitchDIM, DALI and DSI share the /ECO control-gear suffix; Casambi wireless control remains a distinct /BTC choice.
Emergency conversions, integral indicators and decorative bezel accessories are then selected separately.

Specification checksBefore ordering Opti
Ceiling aperture
Confirm the 140 × 140 mm cut-out, 112 mm body height and 5–35 mm ceiling thickness.
Output row
State the required output for OPTI.002 or OPTI.004 because each code has two published performance rows.
Control method
Keep /ECO wired controls separate from /BTC Casambi wireless control.
Compare Opti with the wider commercial downlight range when reviewing aperture, output and control requirements.

Opti details worth checking.
Direct answers for consultants, contractors and commercial lighting buyers.
Five unique codes are published: OPTI.000, OPTI.001, OPTI.002, OPTI.003 and OPTI.004. The current datasheet assigns two performance rows to OPTI.002 and OPTI.004, so state the required output when requesting a quotation.
Fixed 3000K and 4000K models cover 1,200–3,025 lm. OPTI.000 is a 1,725 lm tunable-white model covering 2700–6500K.
The /ECO suffix covers SwitchDIM, DALI or DSI control gear. /BTC provides Casambi Bluetooth wireless control including dimming.
The listed emergency suffixes are /EM, /EMD, /EMI and /EMDI. They separate standard, DALI and self-test conversions from integral-indicator arrangements.
Opti requires a 140 × 140 mm ceiling cut-out, with a 170 × 170 mm bezel and a 112 mm body height.
The LDT archive contains a standard reflector distribution and a distinct DA002 opal-acrylic distribution. The preview excludes OPTI.000 because no tunable-white LDT file is supplied.
