Recessed downlight fixture TIBERI PRO 40W-940-B 35675

Ceiling-mounted fixture, integrated LED 40W

Downlight fixture designed for ceiling installation with integrated SMD LED light source. No bulb replacement required – the entire unit is sealed and maintenance-free throughout its service life. The housing is made of aluminum alloy, while the lens is constructed from synthetic material – combining mechanical durability with lightweight design for easy installation and operational stability.

The emitted light has a color temperature of 4000 K – neutral white, balanced between warm and cool tones. The color rendering index Ra=90 ensures natural color reproduction, while R9=56 enhances red rendering – critical for illuminating walls, furniture, or products in retail environments. Luminous flux is 3800 lm with a luminous efficacy of 95 lm/W – efficient lighting with minimal energy consumption.

The fixture has a beam angle of 90°, delivering a focused yet not overly narrow light distribution – ideal for even illumination of ceiling surfaces. A luminous flux maintenance factor of 0.96 means that after 50,000 hours of operation (over 11 years at 12 hours/day), it will still emit more than 95% of its initial light output.

Installation and Operating Conditions

An opening of Ø210 mm is required for installation. The fixture dimensions are Ø230 mm x 77 mm – compatible with standard joist cavities. Connection via a terminal block – no soldering or direct wiring to LEDs is needed. Installation is straightforward but requires precise hole cutting and proper placement of thermal insulation: the fixture must not be covered by thermal insulation material – this is critical for safety and performance.

The IP44/20 protection rating allows installation in humid environments: bathrooms, kitchens, and basements. This is not an outdoor fixture – it is not suitable for exposure to rain or direct water contact. Operating temperature range: +5°C to +25°C – intended for heated indoor spaces only.

Why This Solution Works:

• No dimming capability – no additional components that could fail.
• Turn-on time under 0.5 seconds – instant illumination.
• Warm-up time ≤1 second – no delay when switching on.
• Service life of 50,000 hours – approximately 17 years with 8 hours of daily use.
• Energy efficiency class E – not the most efficient (A+), but not the worst; results from high power and high-quality LEDs.
• 5-year warranty – among the longest in this product category.
• Chromaticity coordinates (x=0.38 / y=0.38) confirm stable light color over time – no shift occurs.

No anti-glare cover, no motion sensor, no color-tuning capability. This is a simple, robust fixture – without unnecessary features that complicate design and reduce lifespan.
