A waterproof porthole light mounts on the ceiling and encloses its bulb behind glass, giving a downward-directed light and a fixture that is easy to dust. The Hublotia ceiling light in this collection is rated IP20, protected against solid objects but not against water: it is used indoors, in a dry room.
What is a waterproof porthole light?
The name comes from the shape: a ceiling light closed by glass that protects the bulb, like a boat window. The ribbed glass of the Hublotia model lets light through while keeping the bulb safe from dust and contact. This closed-housing principle is found across the entire porthole family, with variations in finish and shape.
What the IP20 rating allows in terms of rooms
An IP20 rating means the fixture is protected against solid objects larger than 12.5 mm, so against fingers and ordinary dust, but no water protection is claimed. That easily covers a hallway, an entryway, a garage or a non-damp workshop. It is an indoor ceiling light, not a fixture for a wet room or a facade.
What not to expect from an IP20 porthole light
No water spray, no permanent condensation, no hose washing. A very damp garage, an unventilated laundry room or a shelter open to the weather are not suitable. If you are looking for a fixture that switches on by itself when you pass through these rooms, it is better to add automation with a model designed for that, but always in a dry area.
In which rooms should you install an oval porthole ceiling light?
The Hublotia ceiling light targets passageways and utility rooms: hallway, entryway, garage and workshop. Mounted on the ceiling, it takes up little height and directs light downward, which suits circulation areas and work zones where you want direct, easy-to-maintain lighting.
A porthole light for hallway and entryway
In a hallway, you want a clear light that does not narrow the passage: the oval format and 8 cm height work in that direction. In an entryway, the same fixture gives a readable welcoming light without glare, and its ribbed glass diffuses the beam. For these two rooms, take a look at the lighting catalogue if you prefer to compare with other ceiling lights.
A porthole ceiling light for garage or workshop
Above a workbench, the light must fall sharply on the work area. A single point may be enough for a small workshop, while a garage of several dozen square metres often requires several ceiling lights aligned to avoid shadow areas. An LED model works well for extended use.
| Room | What you expect from the light | What to check before choosing | Model in the collection |
|---|---|---|---|
| Hallway | Direct lighting that does not narrow the passage | Clearance above doors and the height of the ceiling light | Hublotia oval porthole ceiling light |
| Entryway | A readable welcoming light, without glare | The elongated format if the entryway is narrow | Hublotia oval porthole ceiling light |
| Garage | A clear light on the work area | The number of light points according to the surface to cover | Hublotia oval porthole ceiling light |
| Workshop | Sharp lighting above the workbench | The choice of E27 bulb according to use | Hublotia oval porthole ceiling light |
Is an outdoor waterproof porthole light the same product?
No. A ceiling light rated IP20 is designed for indoor, dry use: it should not be mounted on a facade or under an awning exposed to rain. For an outdoor waterproof porthole light, you need a protection rating that covers water, which this collection does not claim. Turn to the porthole lights designed for outdoor use.
Why IP20 is not enough outdoors
Outdoors, the fixture faces rain, splashes and the lingering morning damp. The IP20 rating protects against none of these three factors: the glass and metal would age poorly, and the bulb would be exposed. The general rule is simple: the damper or more exposed the room, the higher the protection rating must be; that is a trade benchmark, not a specification of this collection.
Which collections to turn to for outdoor use
Outdoor models form a separate family, designed for facades and surroundings. If you also want the light to switch on without intervention, there are outdoor models with a sensor. And for automatic indoor use as well, look at the LED porthole lights with motion sensor.
How to choose the shape and height of an oval glass porthole light?
The Hublotia ceiling light has an oval shape and measures 8 cm in height once mounted on the ceiling. This elongated format suits hallways and narrow entryways, where a large round diffuser would be too bulky. Above all, check the space available between the ceiling and a door or an open cupboard.
The oval format in a hallway or narrow entryway
An oval aligns with the axis of the hallway and dresses a ceiling without weighing it down. In a narrow entryway, it is better to place it along the length of the room rather than perpendicular. It is the same reasoning as for the other shapes in the Designix lighting universe, where you first choose the footprint on the floor and ceiling.
Eight centimetres of height on the ceiling: the clearance to allow
Eight centimetres is little: the fixture stays close to the ceiling and does not hinder movement in a standard-width hallway. Still allow for this clearance above a tall door or a unit with a vertical opening. If you are hesitating between several finishes, the other porthole lights in the collection share the same installation logic.

Which lighting should you choose with an E27 socket in a porthole light?
The Hublotia ceiling light is fitted with an E27 socket, the most widespread in France, and rated for 40 W. That leaves the choice between a classic bulb or an E27 LED bulb, more economical in use. As the ribbed glass leaves the bulb visible, it is better to choose a shape you like.
What the E27 socket implies
The E27 screw socket is found everywhere: you replace the bulb without tools and without changing the fixture, even several years after purchase. The choice of colour temperature is then made on the bulb: around 2700 to 3000 K for a warm light in an entryway, towards 4000 K for a workshop where you want to see clearly. These ranges are general lighting benchmarks.
What the stated power of 40 W represents
The value of 40 W indicates the maximum power allowed by the fixture. With an LED bulb, you light far more than with a filament bulb of the same power, at a much lower consumption. In a hallway, a moderate bulb is enough; in a workshop, you go into the upper range. For prolonged daily use, choosing an LED porthole light simplifies the choice.
How to install and maintain a porthole ceiling light?
The ceiling light is fixed to the ceiling, with the bulb off and the circuit cut at the breaker, following the supplied instructions. Its height of 8 cm limits the clearance needed. For maintenance, a soft cloth is enough on the glass and metal; avoid abrasive products that would scratch the ribbed glass and dull the grey finish.
Ceiling mounting and electrical safety
Switch off the circuit breaker, check that there is no voltage, then work on a stable ladder. The connection is made according to the instructions, without forcing the wires. The fixture is guaranteed for 2 years; if in doubt about the assembly, call an electrician rather than tinkering with the terminal block. The whole set of porthole lights in the collection is installed in the same way.
Cleaning the ribbed glass and grey metal
Unplug or switch off the circuit, let it cool if the bulb has just been on. A slightly damp microfibre cloth is enough on the glass, a dry cloth on the metal. No abrasive sponge, no strong alcohol, no glass cleaner loaded with ammonia: the ribs scratch quickly and the grey finish dulls.
Which interior should you pair a ribbed glass and grey metal porthole light with?
The ribbed glass diffuses the light while letting the bulb show through, and the grey metal stays discreet on a white ceiling. This industrial-style set pairs with a raw hallway, a wood and metal entryway or a workshop. The oval format and grey finish go well with neutral tones, concrete and dark wood.
The effect of the ribbed glass
The ribs split the beam and soften the direct light, which avoids the spotlight effect on the ceiling. On the other hand, the bulb remains visible: a filament bulb with a simple shape looks better than a very wide model. This oval ribbed glass porthole light owes its presence as much to the glass as to the contrast with the metal.
Pairing grey metal and transparent glass
Grey and transparent are two neutral values: they accept a white wall, polished concrete, dark wood or deep blue without clashing. Just avoid copper or gold tones in the same room, which clash with grey. The flagship product of the collection remains the Hublotia ceiling light.
Frequently asked questions about waterproof porthole lights
How many porthole lights should you plan for a hallway or workshop?
It all depends on the length to cover: a long hallway requires several distributed light points, a workshop is often satisfied with one ceiling light above the workbench. As the collection mounts on the ceiling at 8 cm in height, you can align several without hindering movement.
What warranty covers these porthole lights?
The porthole lights in this collection are guaranteed for 2 years. If you have a question before or after purchase, the Designix customer service remains available. Payment is secure, delivery is tracked and returns are provided, which allows you to check the oval format and grey finish once the parcel arrives.
What type of bulb should you put in an E27 porthole light?
An E27 socket accepts the most common screw bulbs, in classic or LED version. The Hublotia ceiling light is rated for 40 W. As the ribbed glass leaves the bulb visible, a simple shape and a model whose light suits you make the result cleaner.
Can a waterproof porthole light be installed outdoors?
No. A ceiling light rated IP20 does not protect against water: it must not be mounted on a facade or under an awning exposed to rain. For an outdoor waterproof porthole light, you need a model whose protection rating covers damp; the outdoor porthole lights collection groups these uses.
How do you clean a glass and metal porthole light?
A soft, slightly damp cloth is enough on the ribbed glass and grey metal. Avoid abrasive sponges and aggressive products, which scratch the glass and dull the finish. Switch off the circuit before any work and let the fixture cool if the bulb has just been on.
Choosing, ordering and installing
The point to settle before ordering comes down to two questions: is the room dry, and is the clearance above the unit or door sufficient. Once these two answers are clear, the oval format, the E27 socket and the 8 cm height of the Hublotia ceiling light do the rest. If you want to complete the lighting of a damp room, a model for the facade takes over.
Secure payment, tracked delivery, returns provided and Designix customer service available: you can check the grey finish and ribbed glass on receipt, with no pressure.
