IP65 commercial downlights
Compare recessed LED downlights available with IP65 protection. Filter the range by lumen output, colour temperature, optical requirement, controls and emergency options, then send us the shortlist for a project-specific check.

Find an IP65 rated commercial downlight
Use the filters to reduce the current range to the families that match your lighting brief. The final product code still needs checking against the ceiling, controls and emergency requirements.
No exact match
Clear one filter to widen the range, or send the requirement to Lumenloop so we can check an alternative configuration.
Bathroom lighting zones and IP ratings
For rooms containing a fixed bath or shower, BS 7671 Section 701 defines zones around the water source. The diagram is a quick briefing aid, not a substitute for an electrical design.
Zones 1 and 2
IET guidance identifies IPX4 as the minimum water-ingress protection in zones 1 and 2, or IPX5 where water jets are likely. An IP65 downlight exceeds that water-ingress minimum, but the full product and installation still need to be suitable for the location.
Zone 0
This is inside the bath or shower basin. Do not assume an IP65 fitting is suitable: specialist equipment and additional electrical restrictions apply.
Showers without a tray
The zone geometry changes where there is no shower basin. The horizontal limit is measured 1.20 m from the fixed water outlet, so the room layout must be checked rather than inferred from this bath example.
Outside the zones
Assess the likely external influences, cleaning method and manufacturer’s instructions. A higher IP rating can be appropriate even where a defined bathroom zone does not demand it.
ProTech IP65 fire-rated LED downlight

Outputs and options shown are from the current ProTech product data. Confirm the exact product code and application before ordering.
How to specify an IP65 commercial downlight
The IP rating is one decision. A useful downlight schedule also fixes the light output, visual comfort, ceiling constraints, controls and emergency strategy.
Confirm the location and IP requirement
Identify moisture, dust and cleaning exposure, then check whether the luminaire’s IP65 arrangement is suitable for the precise location.
Set lumen output and beam distribution
Use the lighting calculation to establish the required lumens, beam, spacing and uniformity rather than selecting by wattage alone.
Choose colour temperature and light quality
Coordinate 3000K, 4000K or tunable white with the space, finishes and adjacent luminaires. Add low-glare or wall-wash optics where the brief needs them.
Check cut-out and ceiling void
Record the ceiling construction, cut-out diameter, available recess depth, insulation and access before committing to a product family.
Define lighting controls
Specify switching, mains dimming, DALI, Casambi or another project control route and confirm the compatible driver configuration.
Coordinate emergency lighting
Where emergency lighting is required, confirm duration, test method, monitoring and the effect of the emergency gear on the installation detail.
IP65 downlight FAQs
Are all IP65 downlights suitable for bathrooms?
No. The IP rating is only part of the assessment. The bathroom zone, supply arrangement, ceiling, manufacturer’s instructions and complete electrical design all affect suitability.
Does IP65 mean the downlight is fire-rated?
No. Ingress protection and fire performance are separate classifications. Select a fire-rated model, such as an appropriate ProTech configuration, where the ceiling construction requires it.
Can an IP65 commercial downlight include DALI or emergency?
Yes, selected Lumenloop families offer IP65 together with DALI, Casambi and emergency options. Availability varies by family and product code, so use the finder and request a final check.
Should I choose 3000K or 4000K?
That depends on the application, finishes and wider lighting scheme. 3000K gives a warmer appearance; 4000K gives a cooler, neutral appearance commonly used in commercial interiors.
