  • Product description

    LED T5 integrated linear luminaire | 12 W | 2700 K | 960 lm | 230 V | 87 cm | frosted | with switch | OPTONICA | TU12-A2-5573 | 3800156655737

    TU12-A2-5573 is a slim surface-mounted LED luminaire with the LEDs, driver and frosted diffuser combined in one housing. This 87 cm, 12 W model delivers 960 lm of warm white (2700 K) light and connects directly to the 230 V mains – no ballast, starter or G5 lampholders needed.

    Key point:
    The 87 cm model is a common choice for the worktop under kitchen wall cabinets or above a workbench. The switch on the housing lets you turn the light on locally without running a separate control cable.

    How it works

    The luminaire is fixed to a surface – the underside of a cabinet, a shelf, a wall or a ceiling – and connected to 230 V AC. The integrated driver converts mains voltage into the current the LEDs need, so no additional ballasts or transformers are required.

    The frosted diffuser spreads the light at a 120° beam angle and reduces glare: mounted under a cabinet, it lights the worktop evenly without bright spots. A colour rendering index of Ra > 80 shows food, materials and paint colours naturally.

    Distributor catalogues list the A1 / A2 series luminaires as linkable into a continuous line. The manufacturer does not publish the maximum number of linked units or total power, so it is worth agreeing a longer line in advance.

    Why choose TU12-A2-5573?
    960 lm from 12 W (~80 lm/W) – a 87 cm line of light with no extra components. Switch on the housing – no wall switch needed.

    Main functions

    • Integrated driver – connects directly to 230 V, no ballast, starter or transformer needed.
    • 960 lm luminous flux – ~1100 lm per metre of length, enough to light a worktop or shelf.
    • Frosted diffuser, 120° – even light without glaring spots.
    • Ra > 80 – natural colours of food and materials.
    • Switch on the housing – turned on locally, without a wall switch or extra cable.
    • Linkable line – several luminaires of the same series form one line with a single supply point.

    Where is it used?

    • Kitchen worktop under wall cabinets
    • Shelves, bookcases and display cases
    • Inside wardrobes, closets and niches
    • Workshop benches, storerooms, dry garages
    • Office furniture, counters and product shelves
    • Accent lighting in dry corridors and stairwells

    Use by need

    For homeowners.
    Warm light on shelves, living-room furniture and niches creates a cosy feel and is easy on the eyes in the evening.
    For furniture makers.
    Built into furniture without a separate driver – only a 230 V connection is needed.
    For shop fitters.
    Warm light brings out wood, textiles and food in display cases.

    Practical use

    If a kitchen cabinet is 100 cm wide (~96 cm inside), the 87 cm luminaire fits and lights almost the whole worktop. Mount it closer to the front of the cabinet so your hands do not cast shadows.

    Pros

    • All-in-one – no separate driver or ballast
    • ~80 lm/W efficacy
    • Frosted diffuser, no glare
    • Colour rendering Ra > 80
    • Switch on the housing
    • Linkable into a continuous line
    • Several lengths and colours in the same series

    Cons / limitations

    • IP20 – dry rooms only
    • Dimming not specified – do not use with a dimmer
    • LEDs cannot be replaced – if it fails, the whole luminaire is replaced
    • Maximum number of linked luminaires not published

    Safety and installation notes

    • Before installation, switch off the circuit at the panel and check that no voltage is present.
    • Do not install in bathrooms, in the splash zone above a sink, outdoors or in damp rooms.
    • Do not install directly above a cooker or oven – plastic housing, heat and grease vapour.
    • Do not connect to a dimmer.
    • Route the cable so that it cannot be pinched by doors or shelves.
    • Connection to a fixed electrical installation must be carried out by a qualified electrician.

    Important reminder: This is not an LED T5 (G5) tube – it does not fit an old fluorescent luminaire. To keep an old housing, choose an LED T5 tube with a G5 base.

    FAQ

    Can it replace an old T5 fluorescent tube?
    No – it is a complete luminaire with an integrated driver and has no G5 pins.
    Will it fit my cabinet?
    Yes, if the internal width between the side panels is at least 90 cm.
    Can it be connected to a dimmer?
    No – dimming is not specified, and with a dimmer the luminaire may flicker or fail.
    Can several luminaires be linked?
    Yes, A1 / A2 series luminaires link into a line; for lines longer than 3–4 units, check the permitted power with us.
    Is it suitable for a bathroom or outdoor canopy?
    No – IP20 offers no protection against water; the luminaire is for dry rooms only.
    Does the switch turn off the whole linked line?
    The switch controls this luminaire, so a wall switch is more reliable for the whole line.
