4ft LED Vapor Tight Light Fixture IP65 Industrial 0-10V DALI2 150W

The ILED-TPR-C M11 is a 4-foot (1200 mm) LED vapor tight luminaire built for industrial and commercial environments where moisture, dust, and physical impact are everyday hazards. The PC (polycarbonate) housing is deep at 105 mm — significantly bulkier than standard triproof tubes — which gives it the structural rigidity needed in high-traffic warehouses and processing areas. The frosted diffuser scatters light at a 120° beam angle, producing an even wash across the floor below with minimal hot spots.

Tech specs

The M11 is offered in three wattages: 80W (10,400 lumens), 100W (13,000 lumens), and 150W (19,500 lumens), all at a rated 130 lumens per watt using LM80-certified LEDs. CRI exceeds 80, so colours in the space — safety signage, product packaging, floor markings — render naturally rather than looking washed out. The 3CCT switch lets you select 2800K warm white, 4000K neutral white, or 6500K cool white at installation. Input voltage covers 110–277VAC or 220–240VAC, meaning the same SKU works in North America (120V), Europe (230V), and most other markets without a transformer. The power factor is above 0.9, keeping reactive power low. The fixture is Class II double-insulated, so no protective earth conductor is required — a useful simplification in retrofit projects where earthing may be absent. The IP65 rating protects against dust ingress and low-pressure water jets from any direction. IK08 impact resistance (5 joules) guards against accidental contact with pallet forks and rolling equipment, though it falls short of IK10 for areas subject to heavy direct impacts.

Dimming and control options

The ILED-TPR-C M11 supports three dimming protocols: TRIAC (leading-edge or trailing-edge phase-cut), 0–10V analogue, and DALI2 digital. Choose the driver option that matches your existing control infrastructure. TRIAC dimming works with most standard wall-mounted dimmer switches and is the simplest retrofit for existing switched circuits. 0–10V is common in commercial building management systems and allows smooth, proportional dimming from 10% to 100%. DALI2 is the most flexible option, enabling individual fixture addressing, scene setting, and integration with fire alarm systems for emergency illumination override. All three dimming options are factory-installed; the driver is not field-replaceable, so select the protocol at order time.

Optional features

Built-in motion sensor and emergency battery modules are available as factory-installed options. The standby motion sensor activates the light only when movement is detected, cutting energy in low-traffic areas such as storage aisles and loading bays. The emergency battery provides approximately 90 minutes of backup illumination on mains failure, meeting exit-path lighting requirements in many jurisdictions. Both options must be specified at the time of order because they occupy internal space within the housing and require different internal wiring.

Build and installation

The housing is moulded polycarbonate in gray, with a frosted PMMA diffuser that diffuses the LED array into a uniform panel of light. The deep 105 mm profile accommodates the driver and optional modules while maintaining a compact overall length of 1200 mm. Suspension is via eye-hooks or pendant mount; surface mounting on solid ceilings is also possible with the appropriate bracket. Cable entry is through sealed gland entries on either end of the housing, supporting daisy-chain wiring for multi-luminaire runs. The IP65 seal is maintained at each cable entry point, so every connection in the chain remains protected.

Certifications and warranty

The ILED-TPR-C M11 carries CE, RoHS, SAA, and TUV certifications. SAA is required for Australian and New Zealand installations. TUV coverage extends validity to European and Middle Eastern markets. The standard warranty is 5 years, which is longer than the 2–3 year warranty offered on several sibling products in the ILED-TPR-C range — confirm warranty terms for your specific order with the sales team.

Why do buyers pick the ILED-TPR-C M11 over other vapor tight luminaires? Here is what we hear from customers:

130 lumens per watt. — Higher efficacy than the 120 lm/W found on older M-series triproofs. Buyers note lower electricity bills and fewer fixtures needed per square metre.

Wide voltage acceptance. — 110–277VAC covers North America and most other regions in one SKU. No transformer needed for 120V sites.

Three dimming protocols. — TRIAC, 0–10V, and DALI2 are all available. Specifiers value being able to match the driver to the building’s existing control system without switching products.

IK08 impact resistance. — 5 joule protection handles accidental contact from pallet forks and trolleys in warehouse aisles.

5-year warranty. — Longer than the 2–3 year warranty on many comparable fixtures. Reduces total cost of ownership for large installations.

Warehouses and distribution centres. — The 150W / 19,500-lumen output covers large bay spans with fewer fixtures. IK08 impact resistance handles occasional contact from forklift masts and pallet forks.

Food processing and beverage plants. — Polycarbonate housing resists corrosion from cleaning chemicals and acidic environments where aluminum would pit. IP65 protects against routine wash-down with low-pressure hoses.

Parking garages and car parks. — The wide 110–277VAC input accepts both North American and international mains without modification. Moisture and vehicle exhaust are no concern with the IP65 seal.

Industrial workshops and factories. — DALI2 dimming integrates with building management systems for scheduled dimming and occupancy-based control. The 3CCT switch lets facility managers set the colour temperature once and leave it.

Loading bays and dock doors. — Frequent open-and-close cycles expose the lighting to temperature swings and moisture. The PC housing and sealed cable entries handle these conditions without degradation.

Agricultural and livestock buildings. — Corrosive ammonia environments attack metal housings. The polycarbonate body is immune to ammonia corrosion, making this a durable choice for barns and stables.

A few things to check before ordering the ILED-TPR-C M11:

Dimming protocol. — Confirm whether TRIAC, 0–10V, or DALI2 is required. The driver is factory-installed and cannot be swapped in the field.

Wattage selection. — 80W, 100W, and 150W are available. The 150W version produces 19,500 lumens — verify this does not exceed the design illuminance for your space.

IP rating for your environment. — If your site requires high-pressure wash-down (IP66) or submersion resistance (IP67), the M11’s IP65 rating may not be sufficient. Select an appropriate sibling model instead.

Motion sensor and emergency options. — Both are factory-installed only. Specify them at order time if needed.

Mounting method. — The M11 uses eye-hook suspension or pendant mount. Confirm your ceiling structure can support the weight and that cable glands are accessible for daisy-chain wiring.

Warranty. — The M11 carries a 5-year warranty, which is longer than some sibling models in the ILED-TPR-C range. Verify warranty terms for your market with the sales team.
