COIN 8038 is a Mantra ceiling light shaped as a flat gold ring 38 cm across. A white acrylic cover fills the ring, and a gold disc closes its centre. The LED module is built in, and colour and brightness are changed with the remote supplied with the fitting.
How big it is and where it goes
The fitting measures 38 cm in diameter and 6.8 cm in height. It does not hang from a cable, so compare its outline and projection with the available space below your ceiling. Net weight is 0.9 kg; use a fixing method appropriate to the installation instructions and ceiling substrate. This listing is for gold variant 8038, not the larger COIN sizes.
The light is protection class I and requires an earth conductor. The instructions show direct ceiling mounting and connection to a 220–240 V supply. The included remote changes brightness and light colour. Mantra lists 2.4 GHz radio control and Bluetooth, but the product card does not specify a guaranteed range through walls.
How much light COIN 8038 gives
The complete fitting delivers 2500 lm at 56 W. Use this figure when comparing it with other complete lights: the separately stated 5360 lm refers to the LED source, not the light emerging from the ceiling fitting. The number of lights needed depends on room size and required illumination, rather than the diameter of the fitting alone.
Colour temperature moves across 2700–5000 K: from warm, yellowish white for the evening to a cool, near-daylight light when concentration is needed. Brightness is adjustable too, so the same fitting runs full for cleaning and dimmed in front of the television. The diodes carry a stated life of 25,000 hours, and the manufacturer gives a five-year guarantee.
Where it works and what it suits
The low-profile ceiling format can be considered for a living room, bedroom, kitchen, dining room or hallway, and for general lighting in an office or study. It does not remove the need to plan lighting for a particular working area. Brightness and colour can be changed without replacing the light source; the fitting does not have adjustable height.
The form is modern: a smooth ring with no ornament, an unbroken gold surface and the white cover as the only contrast. The gold picks up on handles, mirror frames and taps in the same tone, and the low profile does not compete with the rest of the room.
