IP65 light bulbs

The collection includes 54 IP65 bulbs. The 6 keeps dust out, the 5 withstands water jets. They hold up on a facade, on an uncovered terrace, near a shower or in a damp garage, where an ordinary bulb oxidises within a few months.

What is IP65?

IP65 is a two-digit protection rating. The 6 indicates a housing completely sealed against dust, the 5 resistance to water jets sprayed from all directions. An IP65 bulb withstands rain and jet cleaning, but must never be immersed.

IP65 LED bulb: what it changes day to day

The difference shows over time. An ordinary bulb placed under a canopy picks up moisture, blackens at the base and flickers after a season. An IP65 LED bulb keeps a stable output on a terrace swept by rain, in a bathroom where the shower steams up, or in a garage where a wet car is parked. Cleaning follows: a quick jet on the closed fitting, without removing the socket.

IP23 bulbs: what are we talking about?

IP23 protects against solid objects larger than 12.5 mm and oblique rain, not jets. It is a rating for sheltered rooms: a corridor, a pantry, a deep canopy where water never reaches the fitting. Fitting an IP23 bulb on an exposed facade is like letting water in through the top of the socket. For real exposure, compare with the 220V LED bulbs designed for outdoor use.

What is the difference between IP44 and IP65?

IP44 protects against solid objects larger than 1 mm and water splashes, but not jets. IP65 adds total dust tightness and resistance to water jets. In a bathroom, IP44 is enough away from water points; near the shower or in exposed outdoor areas, IP65 is the right level.

IP44 or IP65 for the bathroom?

It all depends on the distance from water. More than a metre from the bath, an IP44 mirror wall light does the job. Above the shower, on a side wall of the bath, you need a rating that withstands direct splashes, so IP65. The fitting matters as much as the bulb: an upward-facing socket will retain water even with a well-protected bulb.

IP65, IP66, IP68: how far does sealing go?

The two digits rise together. IP66 adds resistance to powerful jets, such as a pressure washer or sea spray. IP68 goes as far as continuous immersion under conditions set by the manufacturer, which concerns pool fittings. IP68 is therefore the most sealed of the three, IP65 remains the standard level for non-immersed outdoor use.

What each rating protects against

Which IP for outdoor lighting?

Outdoors, aim for at least IP44 under a sheltered canopy, and IP65 as soon as rain or a pressure washer jet can reach the bulb: facade, uncovered terrace, low wall, gate. IP65 covers driving rain without immersion. Beyond that, only a seaside location justifies IP66.

IP65 outdoor bulb: terrace, facade or garden?

On a covered terrace, water arrives through wind and condensation: IP65 secures the installation without technical extra cost. On a facade, under a porch or against a low wall, it is the minimum. In the garden, on a post or a low lamp post, the bulb takes the full force of rain and sometimes the spray from watering. A closed globe model in glass bulbs protects the source better than an exposed bulb.

Under a canopy or in the open air: which rating to choose?

Under a deep canopy, the bulb stays dry: IP44 is enough and leaves more choice of shapes. As soon as the canopy is short or lateral, driven rain reaches the fitting: move to IP65. The useful rule is simple: if you can imagine water running down the socket, choose IP65.

IP65 bathroom bulb: which one to choose?

In a bathroom, the bulb is chosen according to its distance from the shower or bath: closest to water points, an IP65 model protects against direct splashes; further away, IP44 is enough. An E27 or GU10 LED base, in warm white, keeps the room gentle when you wake up.

IP65 bathroom bulb: near the shower or the mirror?

Above the mirror, you want light that illuminates the face without casting shadows: a diffusing model, in IP44 if the mirror is at a distance from the bath. In the shower zone, the bulb takes splashes every time: IP65 mandatory, and socket facing down. For a very damp room without extraction, the high rating compensates for insufficient ventilation.

Warm white or neutral light in the bathroom?

Warm white, around 2700 K to 3000 K, softens the tiling and remains bearable in the middle of the night. A neutral white around 4000 K renders skin tones more accurately in front of the mirror and suits rooms without windows. The choice is made before the power, otherwise you are just lighting a colour you do not like more strongly. See the 2700K bulbs and the 3000K bulbs.

IP65 bulb E27, E14 or GU10: which base to choose?

The base depends on the fitting, not on the IP rating: E27 for pendants, ceiling lights and wall lights, E14 for small volumes and table lamps, GU10 for recessed or directional spotlights. Check the base marked on the socket before ordering an IP65 bulb. The collection includes 54 IP65 bulbs; PAR30 and PAR38 reflector shapes are not listed.

IP65 E27 bulb: pendants, ceiling lights and wall lights

The large screw base fits most terrace and entrance fittings. It accepts bulbs of classic shape, globe or bulb, and can be changed without tools. On an outdoor pendant, keep an eye on the globe diameter: a bulb that is too wide touches the diffuser. The range continues with the E27 base bulbs and the E27 LED bulbs.

IP65 GU10 bulb: outdoor spotlights and recesses

Pin-base spotlights clip into a GU10 socket, often directional. They suit terrace recesses under a canopy, bathroom ceilings and low-wall rails. The point to check is the recess depth and the reflector shape, because not all spotlights fit into all housings. The GU10 spotlights cover this need.

E14 bulbs: small volumes and table lamps

The small screw base is used for mirror wall lights, bedside lamps and compact fittings. In damp areas, the choice is more limited than in E27, so check the rating before the shape. For a corridor or a bedroom adjoining the bathroom, the E14 bulbs are often enough.

Which base for which fitting

How to wire 3 bulbs in parallel?

To wire three bulbs in parallel, each socket receives the live and neutral from the same line: the three are powered independently, if one blows, the others stay on. The connection is made with the power off, using connector blocks or wago connectors, in a box suited to humidity.

The diagram: live, neutral and three sockets

The line arrives in a box. The live goes out to each socket, the neutral follows the same path, and the earth joins the fitting when it is metal. Three branches, no loop: this is a parallel circuit, unlike a series circuit which would switch everything off if one bulb was missing. Switch off at the breaker before opening the box, never just at the switch.

What changes with IP65 bulbs outdoors

Outdoors, the weak point is not the bulb but the connection. The box must be placed away from splashes, with cable glands facing down and cable glands tightened. An open box under a terrace cancels the IP65 of the bulbs within two rains. For a low-voltage garden line, turn to the 12V bulbs and their waterproof transformer.

IP65 LED bulb: warm white or neutral white?

Outdoors, a warm white around 2700 K to 3000 K lights a terrace without a bluish effect and remains comfortable in the evening. A more neutral white, around 4000 K to 5000 K, makes outlines sharp near an entrance or a staircase. Temperature is chosen before power.

2700 K or 3000 K: which atmosphere on a terrace?

At 2700 K, the light leans towards amber and brings the outdoors closer to the living room: perfect for a table, a summer dining area, a pergola. At 3000 K, the rendering remains warm but sharper, which helps to see steps and the edge of the pool. Both are also chosen according to the wall: a light render reflects a lot of light, dark wood cladding absorbs it.

Neutral white: for passage areas and entrances

An outdoor staircase, a garage or a porch gain in legibility with a neutral white: steps, tools and locks are easier to distinguish. In a corridor at night, the difference is clear and avoids lighting up the whole floor. If you want to adjust the intensity according to the time, check compatibility with the dimmable LED bulbs.

How to install and maintain an IP65 bulb?

An IP65 bulb screws in like any other, but the fitting's seal does half the work: a badly closed housing or an upward-facing socket lets water in. Clean with a damp sponge, without a direct jet on the socket, and check the seal once a year.

Screwing in an IP65 bulb without damaging the seal

Switch off the power, let it cool, then screw in by hand without forcing: excessive tightening deforms the O-ring and creates a water passage. Check that the seal is in place and flexible before closing the diffuser. A downward-facing socket naturally drains water, unlike a vertical upward-facing socket which retains it.

Cleaning the fitting and renewing the seal

A damp sponge is enough on the diffuser, with a mild product, never solvent on plastic or screen-printed glass. The seal should be replaced as soon as it hardens or whitens, generally after a few years outdoors. To find the right fitting to receive the bulb, browse the Designix lighting catalogue and our terrace and bathroom fittings. For the light source, also compare the LED bulbs and the white-coloured bulbs if the fitting has a tinted diffuser.
