Telbix Sky LED ceiling light buying guide
Sky is a Telbix LED ceiling light built to sit almost flat against the ceiling. The fitting on this page is the Sky 24W round ceiling light in white: 30 cm across and 25 mm high, with an integrated LED, three colour temperatures and a dimmable driver. It gives 2600 lumens, a colour rendering index above 85 and an IP44 rating, with a polycarbonate body and diffuser.
Below you will find why a thin flush fitting suits a low ceiling, how bright 2600 lumens is in a real room, how the three colour temperatures and the dimming work, what IP44 allows and what the installation requires. It also covers what the range leaves out.
What the Sky ceiling light is
The fixture and the diffuser are polycarbonate, the fitting weighs 0.7 kg and the 24W LED is part of the fitting. It runs on 240V, carries no lead or plug and lists surge protection. The profile is an ultra-thin flush mount and the white diffuser spreads the light evenly.
The electrical protection is Class II, double insulated, with earth not required. The beam angle is 120 degrees. The box holds the ceiling light and the instruction manual, and the LED needs no globe.
A thin fitting for a low ceiling
A fitting that sits 25 mm from the ceiling takes almost no room below it. Flush and semi-flush ceiling lights provide a decorative element that works well in rooms with lower ceilings. Flush mount lights are mounted with little or no space between them and the ceiling, and they suit rooms where a pendant would hang too low, such as bedrooms, bathrooms and hallways.
The Sky is 25 mm high. That is the figure to hold against a door, a cabinet or a person's head. It is small beside the 6 cm projection of the Lyric oyster and the 9.5 to 10 cm projection of the Orlin oyster.
2.4 m is the minimum ceiling height for a habitable room and 2.1 m for a bathroom, laundry or corridor. Flush mounts suit a ceiling that is exactly 2.4 m, and the Sky is a flush mount of that kind.
Surface mounted and what that means
A surface mounted ceiling light is installed directly onto the face of the ceiling, which makes it a visible design feature. A recessed downlight sits in the ceiling cavity for a minimal look. The Sky is the first kind. It stays visible, and its plain white round form is the design.
The choice between the two follows the ceiling. A surface mounted fitting suits a ceiling with no void above, such as a concrete slab, and a ceiling with a cavity can take either type. The ceiling lights page covers the wider range of ceiling fittings.
Choosing a size
The Sky in this collection is 30 cm across. 20 to 30 cm suits hallways, laundries and small bedrooms, and 30 to 40 cm suits standard bedrooms and studies. A 30 cm fitting sits at the top of the first band and the bottom of the second. Two smaller fittings may spread light more evenly than one large one in a big room.
How bright 2600 lumens is
The Sky gives 2600 lumens from 24W. Lux targets are lumens per square metre: 150 to 300 for a living room, 100 to 200 for a bedroom or hallway, 300 to 500 for a kitchen and 300 to 400 for a laundry. Relaxed living spaces need about 100 to 150 lumens per square metre and kitchens and workspaces 250 to 350 or more.
Room by room
A close-to-ceiling light belongs in certain rooms. Flush mounts suit bedrooms, bathrooms and hallways, and a 30 to 40 cm oyster suits a standard bedroom or study. 3000K suits bedrooms and lounges, 4000K suits kitchens, hallways and living areas, and 5000K suits garages and workshops. The Sky at 3000K suits a bedroom, at 4000K a hallway or a living area, and at 5000K a workroom.
4000K also suits kitchens and laundries, and 5000K to 6000K suits garages and home offices. The Sky has no 6000K step, so its cool setting is 5000K.
Three colour temperatures
The Sky offers three settings: 3000K, 4000K and 5000K, named warm white, natural white and cool white. Colour temperature is measured in kelvin. Warm white from 2200K to 3000K suits relaxed areas such as lounges and bedrooms and cooler light from 3000K up suits kitchens and laundries. 4000K is the safest single choice for open-plan living, and 5000K is crisp and energising, good for garages, workshops and detailed tasks, and cold in a living space.
The colour temperature is selected via a switch inside the fitting. The setting is therefore made on the fitting and not from a remote.
Colour rendering
The Sky has a colour rendering index above 85. 80 and above is desirable where colour matters, and 90 or higher suits living areas, kitchens and bathrooms. A figure above 85 meets the first number and falls short of the second, so the Sky suits general room light more than critical colour work.
Dimming and the dimmer
The Sky is dimmable, with a TRIAC driver, so the type of dimmer matters. A leading edge dimmer cuts the start of each half-cycle, which is harsher on LED electronics, and a trailing edge dimmer is gentler on LED drivers and generally dims more smoothly. LED fixtures are usually dimmable but often need a specific trailing-edge dimmer, so check that the fixture and the wall switch are compatible to avoid flicker or buzzing.
A dimmer has a minimum load, and a circuit whose LED wattage falls below it can flicker, glow when off or switch unreliably. A single 24W fitting is a light load, so the electrician can check the dimmer's minimum and match it to the Sky before the dimmer is bought. Confirm that every LED on a circuit is dimmable and of a matched type.
What IP44 allows
The Sky is IP44. The zones above a bath or shower and around a basin need a minimum of IPX4, so IP44 meets that figure. It does not make every ceiling position suitable, because zone 1 has a height limit of 2.25 m or 2.5 m depending on the layout, and a ceiling above that height sits outside the zone. Confirm the zones against AS/NZS 3000 with a licensed electrician. The IP rating also decides whether a flush fitting suits an indoor or an outdoor position.
The IP44 rating means the rating alone does not limit the Sky to a dry room. The bathroom lighting page holds fittings chosen for bathrooms, and an electrician can place a particular ceiling in a zone before a ceiling light goes there.
Installation and who does it
The installation follows a sequence. Turn the mains power off, remove the bracket from the lamp body and mount the bracket with the screws provided, using wall plugs if necessary. Open the junction box, connect the mains wiring to the terminal block and refit the junction box. Select the colour temperature with the switch, mount the light into the bracket, make sure it is locked and turn the power back on.
The product must be installed by a licensed electrician. Installing or replacing a hard-wired oyster involves 240V and must be done by a licensed electrician, who makes sure the wiring is safe, the mounting is secure and the work meets Australian standards. The 0.7 kg weight is part of the mounting, and no fixing limit is given, so the electrician decides how the bracket is secured to the ceiling.
Care
Do not use strong liquid cleaners, and wipe the fitting clean with a dry cloth. Turn the power off at the wall switch or the circuit breaker, let the fitting cool and avoid harsh chemicals on the finish. Allow at least 30 minutes after the light is off, use a dry lint-free cloth and keep water off the fixture. Regular dusting means cleaning only once or twice a year.
If the LED ever fails
An integrated LED has no bulb to swap. Most integrated LED ceiling lights have no replaceable bulb, so a failed board or driver usually means a replacement fitting, and damaged house wiring is a job for an electrician. A typical LED lasts 25,000 to 50,000 hours and uses up to 75 to 85 percent less electricity than incandescent or halogen light.
Replacing an older ceiling light
The old oyster is a bulky, yellowish plastic bowl with a circular fluorescent tube that could flicker, and the modern LED version is a slim fitting that uses far less power. A 25 mm Sky is a flatter replacement for that look. A swap involves wiring, so the old fitting comes down and the Sky goes up as one electrician job, and the work covers the bracket, the junction box and the terminal block.
What Sky leaves out
Sky is a ceiling light with a fixed 25 mm profile. It is not a pendant, a wall light or a downlight, and it is not an outdoor fitting. For a hanging light, the pendant lights page covers the pendants. The Telbix Lyric indoor lighting and Telbix Orlin indoor lighting pages describe two Telbix oysters in wood finishes. The lighting collection shows every category in one place.
Choosing the Sky ceiling light
The decision follows the ceiling and the room. A low ceiling and a room that needs even general light suit the Sky. A kitchen or a laundry may suit the cooler settings, and a bedroom or lounge suits 3000K. The dimmer, the junction box and the colour setting are the three items to settle with the electrician.
Before buying, check the ceiling height, the room size, the colour temperature setting, the dimmer and the position against the IP44 rating. The electrician can confirm the rest on site.
