Technical Description
Corridor LED bulkhead specification for Sentinel.
Sentinel is a corridor LED bulkhead built for wall or ceiling mounting, with a durable polycarbonate housing and a high transmission opal diffuser suited to stairwells, corridors and store rooms. The family sits in the surface-mounted bulkhead category rather than the downlight category, so the page copy now reflects that narrower commercial fit.
Model codes SENTINEL.001 to SENTINEL.008 cover outputs from 1450 lm to 3925 lm across 11 W, 15 W, 20.5 W and 28 W steps, with fixed 3000K and 4000K options. That gives the range a clear spread for corridor, circulation and back-of-house spaces that need a more robust surface-mounted luminaire.
Source information also points to >72,000 hours (L80 / F10), >125 llm/tcW efficacy, 3-step MacAdam colour consistency, 2 x 20 mm conduit entry points and a control set that includes occupancy, mains dimming, DALI, Casambi and emergency variants.
Specification-led corridor bulkhead features.
- High transmission opal diffuser: Low spotting diffuser detail for cleaner corridor and circulation lighting.
- 1450 lm to 3925 lm output spread: Covers lower and higher output bulkhead requirements within one family.
- >125 llm/tcW efficacy: Useful where corridor and back-of-house schemes are balancing output and circuit load.
- Wall or ceiling mounting: Surface-mounted bulkhead format for circulation spaces, stairs and service spaces.
- TP(a) polycarbonate construction: Durable body and diffuser build with two 20 mm conduit entry points.
- Controls and emergency: Occupancy (/SO), mains dimming (/SD), DALI / SwitchDIM / DSI (/ECO), Casambi (/BTC), 3-hour emergency (/EM) and self-test / DALI emergency (/EMD).
- Product life: Listed at >72,000 hours (L80 / F10).
- Model codes: SENTINEL.001 to SENTINEL.008.
Body And Mounting Detail
Sentinel bulkhead construction.
Sentinel uses a durable polycarbonate body with a high transmission, low spotting opal diffuser, giving the family a tougher surface-mounted format for circulation spaces and utility areas.
The supplier record also lists wall or ceiling mounting and 2 x 20 mm conduit entry points, which are the practical build details behind its corridor LED bulkhead positioning.

Specification reasons
Why specify Sentinel?
Diffuser
High transmission opal diffuser
Low spotting opal diffuser detail for cleaner circulation and utility lighting.
Performance
Efficacy above 125 llm/tcW
Useful where corridor schemes are balancing lumen output and circuit load.
Consistency
3-step MacAdam
Keeps colour appearance tighter across repeated bulkheads in the same scheme.
Mounting
Wall or ceiling surface mounting
Suited to corridor, stairwell and store-room positions that need a surface-mounted fitting.
Construction
TP(a) polycarbonate construction
Durable body and diffuser build with conduit entry detail for tougher service areas.
Controls
DALI, Bluetooth and emergency options
Occupancy, DALI, Casambi and emergency variants broaden the family without changing the core fitting.
Product FAQs
Sentinel specification questions.
Common specification questions around Sentinel as a corridor LED bulkhead.
What makes Sentinel different from a standard LED bulkhead?
Sentinel is a corridor LED bulkhead with a polycarbonate body, an opal diffuser and a wall or ceiling mounting format aimed at stairwells, corridors and store rooms.
Where is Sentinel intended to be mounted?
Supplier information lists Sentinel for wall or ceiling mounting, which is why the page is now targeted as a surface-mounted corridor bulkhead rather than a recessed fitting.
Which outputs, wattages and colour temperatures are available?
The current family covers 1450 lm to 3925 lm across 11 W, 15 W, 20.5 W and 28 W models, with fixed 3000K and 4000K options.
What controls and emergency options can be specified?
Listed suffixes include occupancy (/SO), mains dimming (/SD), DALI / SwitchDIM / DSI (/ECO), Casambi wireless (/BTC), 3-hour emergency (/EM) and self-test / DALI emergency (/EMD).
What construction detail is listed for Sentinel?
Source material points to a polycarbonate body, a TP(a) rated opal diffuser and 2 x 20 mm conduit entry points as the key build details.
Are photometric, BIM or installation files available?
Available resources include the datasheet, installation guide, photometric data and BIM file.
What product life is listed for Sentinel?
The family is listed at >72,000 hours (L80 / F10).
