You have found a round stone ceiling light you like. You want it in the bathroom, just outside the shower. Then you see a small code on the spec sheet: IP65.
Most people read IP65 as “waterproof” and stop there. The real IP65 meaning is more exact, and more useful. Each digit tells you one thing the light can take.
Below, you will see what the two digits say. You will also see where a bathroom light needs them, and how our own lights compare.
The short answer
The IP65 meaning is simple: the light is dust-tight, and water jets from any side cannot harm it. IP is a code from IEC 60529, the world standard for how well a casing keeps things out. An IP65 light suits a bathroom ceiling near the shower, while an IP20 light belongs in dry rooms.
What the 6 and the 5 in IP65 mean
The first digit is about solids, from fingers down to fine dust. The number 6 is the top level, and the standard calls it “dust-tight”.
Testers prove it with talc, the same fine powder in a baby-powder tin. The light sits in a cloud of talc for 8 hours, with a light vacuum pulling air inside. No dust may get in.
The second digit is about water. The number 5 means “protected against water jets”, so water sprayed from any side does no harm.
The jet test is strong. A nozzle 6.3 mm wide sprays 12.5 litres a minute at the light, from about 3 metres away. The spray runs for at least 3 minutes.
Do the sum. 12.5 litres a minute for 3 minutes is 37.5 litres of water, all aimed at one light.
IP65 is still not made for life under water. The standard keeps a higher number, 7, for a short dip in water. So an IP65 light goes on the ceiling, not inside the tub.
| Second digit | What the standard says | Where it fits |
|---|---|---|
| 0 | Non-protected | Dry rooms only |
| 4 | Protected against splashing water | Near a wash basin |
| 5 | Protected against water jets | Above or beside a shower |
| 7 | Short immersion in water | Inside a bath or shower |
Most of our indoor lights carry IP20, 334 of 420 products in all. The 2 means a finger cannot touch the live parts. The 0 means the light has no water protection at all.
IP rating for bathroom lights: where each one goes
The UK wiring rules, BS 7671, split a bathroom into zones by how wet each part gets. We use them here because they draw the lines clearly. Your electrician still follows the rules where you live.
- Zone 0 is inside the bath or shower tray. A light there needs at least IPX7 and must run on 12 volts or less.
- Zone 1 is the space above the bath or shower, up to 2.25 m from the floor. IP65 is the rating recommended here.
- Zone 2 runs 60 cm out from zone 1. A light there needs at least IPX4. Treat the space within 60 cm of a basin tap the same way.
- Outside these zones, a light needs no IP rating, as long as nobody cleans the room with a water jet.
The “X” in IPX4 just means the dust digit was not tested. Only the water digit counts in these zones.
So the IP20 vs IP65 choice comes down to distance from water. Over the shower, pick IP65. In the dry dressing corner, far from the tap, an IP20 light is fine.
We counted our own range to see how often IP65 shows up. On 26 Oct 2026, 9 of our 16 ceiling lights were IP65. 56% is the highest share of any light family we make. Across all 420 published products, 50 were IP65, or 12%.
How our ceiling lights follow the IP65 rule
Our Pebble Dome alabaster ceiling light is the clearest case. The dome is 40 cm wide and 10 cm deep. A built-in 12W LED gives warm 3000K light, so no bulb is needed. The light is IP65, sealed against dust and water, and the product page names bathrooms as a fit.
Alabaster is stone formed beneath the earth. Our craftsmen carve and polish each dome by hand in our Greater Noida factory, where we have made lights since 2015. Switch it on and the stone glows from inside, veins and all.
Stone is not the only choice. The travertine passage ceiling light pairs a travertine bowl with a wood canopy and an opal borosilicate glass globe. The light is only 15 cm wide and 12 cm tall, and rated IP65 too. We list it for passages, porches and covered balconies.
Some of our ceiling lights are IP20, and we say so. The travertine foyer ceiling light is 20 cm wide and IP20. We made it for an entrance hall, not near a shower.
Our legal policies keep the promise plain. The built-in LED carries a 1-year warranty, and stainless steel parts carry a lifetime warranty against rust, for orders from 4 Oct 2026. Water that gets in beyond the stated IP rating is not covered. So match the rating to the spot.
Natural stone and warm light in a calm bathroom is the kind of harmony Vastu thinking has always valued.
FAQs
What is the IP65 meaning on a light?
The IP65 meaning is that the light is dust-tight and protected against water jets from any direction. The 6 is the top dust level in IEC 60529, and the 5 means a 12.5-litre-a-minute jet does no harm.
Is an IP65 light waterproof?
An IP65 light is water-resistant, not made to sit under water. The rating covers jets and steam on a ceiling. A light inside a bath or shower tray needs IPX7, which covers a short dip in water.
Can I use an IP20 light in a bathroom?
Yes, but only outside the wet zones. Under the UK zone rules, that means more than 60 cm beyond the space above the bath or shower, and away from water jets.
IP20 vs IP65: which is better for a bedroom?
Either works in a dry bedroom. An IP20 light is enough there, because the 0 only matters where water reaches. Pick IP65 for bathrooms, porches and covered balconies.
Does an IP65 light need a special electrician?
Any licensed electrician can fit it, but the seal only works when the light is fitted as instructed. The UK rules also ask for a 30 mA RCD, a safety switch that cuts power fast, on a 240-volt light in zone 1. We give free installation help on a video call.
Nature gives the material. Human hands give it meaning. Vastu inspires harmony. Light brings it to life. That is JagMag.
