These guides are built from the selection sheets we use on real projects — large supermarkets, commercial fit-outs, residential schemes, railway stations and metro systems. Each one tells you which housing series fits the environment, what IP rating the space demands, and how many watts the ceiling height will actually need.
High ambient light, very long operating hours, and humidity in the fresh-food zones. Ceilings are usually washed or wiped down, so the housing seal matters as much as the output.
General aisles: Huahang 60–100 W IP65, 60° beam.
Fresh & deli zones: Yushen COB IP65 20–30 W, CRI 97.
Back-of-house: LED panel 48 W, 4000 K.
Continuous operation, dust, vibration, and maintenance only inside short overnight windows. Everything here should be serviceable from below without disturbing the ceiling.
Concourses: Huahang 100–150 W IP65.
Corridors & platforms: Ruihang 60–80 W IP65, quick-mount.
Signage & vault: linear aluminium profiles, continuous runs.
Visual comfort comes first: low glare, tight beams, and finishes that read as premium under inspection. Guests notice reflected light in a screen or a polished floor more than they notice lux levels.
Guest areas: Convoy 2″–3.5″ 12–25 W, CRI 97, 15–36°.
Displays & art: Bauhaus Great Wall 10–25 W, 24° narrow.
Cove & curtains: Great Wall wall washer 3 W × 4/8.
Screen glare is the deciding factor, not raw output. Low UGR and an even ceiling field matter more than lumens per watt on a spec sheet.
Open plan: Glory linear UGR ≤ 16, 40/60/80 W.
Meeting rooms: LED panel 600×600, 4000 K.
Feature ceilings: magnetic track, 10–40 W flood.
Layouts change and displays move. Track systems let the lighting be re-aimed without touching the ceiling, which is what shopfitters and interior designers ask us for most.
Display & shelving: magnetic track, grille 6–24 W.
Feature point: Rome surface COB 10–18 W, CRI 97.
Seamless ceilings: trimless round 2″–2.5″, 10–18 W.
High ceilings, wide spans, and dust that settles on the optic. Thermal headroom and a cleanable reflector surface decide whether the fitting lasts the depreciation period.
Workshops: Huahang 150 W IP65.
Storage aisles: 100–120 W, 60° wide beam.
Offices & canteen: panel 48–100 W, 4000 K.
If you already know the environment and the ceiling height, this table gets you to the right series in one step. Every series links through to its full dimensional table.

Decorative and architectural indoor fittings: magnetic track, linear luminaires, trimless downlights. Not suitable where the ceiling is washed or exposed to condensation.
Semi-recessed and surface-mounted general lighting in offices, corridors and most commercial ceilings. Protected against dust ingress and splashing water.
Supermarket fresh zones, loading bays, metro platforms, workshops and semi-outdoor canopies. Sealed against water jets — the correct choice wherever the ceiling is cleaned with water.
Share the schedule of areas or a bill of quantities. We will come back with series, wattage and beam angles for each space — or tell you honestly if it falls outside our range.
