Choose the output and colour temperature first, then add the body, control gear, emergency, lens, baffle and accessory suffixes required.
Miniature architectural LED downlight with fixed and tilt bodies.
Prism is a compact recessed LED downlight with a 76 mm die-cast bezel, 67 mm ceiling cut-out and matt black low-glare baffle. The standard white bezel is RAL 9016, while fixed, tilt and black body variants are available through the verified body suffixes.
Output, colour quality and optics
Nine Tridonic SLA Essence models cover 725–1,275 lm at 9.5 W, 10.5 W or 14.0 W. Each power group is available in 2700K, 3000K and 4000K, with CRI 90 colour quality and 3-step MacAdam consistency.
The standard lens is 36°. The /NB suffix provides a 24° lens, while /SNB provides a 12° lens and is not available with PRISM.004, PRISM.005 or PRISM.006.
Control gear and emergency
Standard models are non-dimmable. /MDIM is phase-cut mains dimming; /ECO requires SwitchDIM, DALI or DSI control gear; /BTC is the Casambi wireless option.
Remote-indicator emergency options are /EM, /EMD for DALI or self-test emergency, and /EMM for wireless mesh emergency. Control gear and emergency options are not available with PRISM.001, PRISM.002 or PRISM.003.
Service life and finish variations
Lumen maintenance is L70/B50 at more than 50,000 hours and the datasheet lists a five-year warranty. Non-standard connector, RAL colour and LSOH/LSF cable arrangements are Custom configuration.
See the Lumenloop commercial downlights range for related mounting, output and optic options.

Why specify Prism?
Prism keeps the ceiling aperture small while offering nine output and colour-temperature combinations, fixed or tilt bodies and three lens families.
Its Tridonic SLA Essence engine, CRI 90 colour quality, low-glare baffle and verified control and emergency suffixes provide a detailed architectural specification in a compact body.
One compact family, three power groups
The 9.5 W, 10.5 W and 14.0 W model groups cover outputs from 725 lm to 1,275 lm, each in 2700K, 3000K and 4000K.
Body heights are 80 mm, 90 mm and 110 mm across the model groups, with a common 76 mm bezel and 67 mm cut-out.
Matt black baffle and a published low-glare value below 19.
Choose the standard fixed body or the verified /T and /BLT tilt variants.
All nine model codes use CRI 90 engines with 3-step MacAdam consistency.
Phase-cut, SwitchDIM, DALI, DSI and Casambi arrangements are separated by control gear suffix.
The 67 mm cut-out and 76 mm bezel keep the recessed ceiling detail compact.
Use the standard fixed body where the beam remains centred below the fitting.
Use the tilt-body variants where the light direction needs adjustment.
The recessed optical assembly and matt black baffle reduce the brightness visible at the aperture.
