Brilliant | Heat Fan Light 1000W 55W Motor 500m³/hr | Tri-Colour LED White
The Brilliant 21478-05 Marvel is a 3-in-1 bathroom heat, light, and exhaust fan combining a 1000W instant heat infrared lamp, a 55W long-life ball bearing motor extracting up to 500m³/hr, and twin 8W LED lights with adjustable colour temperatures (3000K, 4200K, 6000K). Rated 240V / 50Hz, IPX2, with a 3-year in-home warranty and 475mm x 325mm ceiling cutout, the 21478-05 delivers complete bathroom comfort in a modern low-profile design. Also available in matt black (SKU: 21478-06).
Modern bathroom renovations and new builds often require heat, light, and ventilation in tight spaces. The Marvel 3-in-1 combines all three functions into a single ceiling unit, removing the need for separate heat lamps, exhaust fans, and downlights. This integration reduces the coordination challenge of multiple components and cuts the number of wall switches required. The low-profile slimline design suits contemporary bathroom aesthetics without the bulk of traditional triple-function units.
Sparkies and builders favour the Marvel for its straightforward installation — the unit ships with a 3-gang wall switch, 1.5m flexible ducting, duct clamps, and exterior grille, so the job is complete on arrival with no need to source accessories. The powerful 55W motor extracts up to 500m³/hr, handling moisture and steam effectively in medium to large bathrooms. The 1000W infrared heat lamp delivers instant warmth, and the adjustable colour-temperature LED lights (3000K to 6000K) allow clients to choose their preferred lighting mood. The integral thermostat switch automatically turns on the fan if internal temperature exceeds 50°C, adding passive protection against humidity buildup. Repeat customers often buy the Marvel for multiple bathrooms in a project, citing the balance of performance, design, and total cost of ownership.

Where to use
- Bathroom renovations and new builds — the Marvel 3-in-1 is a common specification in modern bathroom projects where space-saving and multi-function integration reduce the number of ceiling penetrations and wall controls.
- Medium to large residential bathrooms — the 500m³/hr extraction capacity handles moisture and steam removal in master ensuite and family bathroom applications without requiring secondary ventilation.
- Rental properties and holiday homes — provides complete bathroom comfort (heating, ventilation, lighting) in a single fixture, simplifying maintenance and reducing guest complaints about cold bathrooms or poor ventilation.
- Extension and addition work — easily retrofitted into new ceiling spaces during extensions, often preferred over installing separate heat and exhaust units due to the reduced footprint and single wall switch.
- Bathroom upgrades from single fixtures — clients replacing an ageing heat lamp or exhaust fan often choose the Marvel to gain heating, ventilation, and lighting in one modern assembly.
- Commercial bathrooms in office and hospitality settings — the unit's compliance with AS/NZS standards and 3-year warranty make it suitable for shared facilities in hotels, offices, and public buildings.
- Colour-temperature-conscious installations — where clients want adjustable lighting (warm for evening, bright for morning grooming), the tri-colour LED option eliminates the need for a separate dimmable downlight.
The Brilliant 21478-05 is not suitable for external walls, damp exposed locations, or splash-zone installations. Do not install the Marvel in bathrooms with direct water exposure (such as wet areas beside showers), outdoor bathrooms, or covered patios where rain or moisture can reach the unit. The IPX2 rating protects against dripping water in normal bathroom humidity but not direct spray or immersion. For external bathroom applications, consider a weatherproof heat lamp model instead.
