Ta: -30°C .. +45°C; Max +55°C (HT version); Max +70°C (VHT version);


X-TIGUA, Palazzoli’s new suspension system, is the optimum lighting solution for places with high ambient
temperatures, such as in steelworks or at the great heights required in shipyards and hangars.

A die-cast aluminium body with very low copper content, anti-corrosion treatment, and a 4mm thick diffuser in extra-clear tempered glass guarantees the durability of this luminaire. It is available in 2 sizes (M and L), providing actual output of up to 49000 lm.

The rear heat sink allows for excellent heat management and increases the longevity of the luminous flux. The product is equipped with DALI drivers, which allow point-to-point adjustment of the lights, resulting in a further energy saving. The power supply unit guarantees excellent light quality with <1% flicker, allowing for video surveillance and for installation where there are rapidly rotating machines.

The input surge protection secures the device against surges up to 8kV, extending product lifetime by protecting the LEDs from possible overloading. Latest-generation CSP (Chip Scale Package) LEDs can maintain luminous flux over a period of more than 120,000 hours, even in ambient temperatures up to +55°C or 100,000 hours in temperatures up to +70°C. The 4000K colour temperature and CRI≥80 guarantee ideal lighting quality wherever the product is installed.

The optics are made using non-ageing, UV-resistant PMMA lenses with >90% efficiency and >95% transparency. The connector supplied with the luminaire allows for fast and secure cabling. X-TIGUA is equipped with quick connecting
suspension brackets and, with specific accessories, can be ceiling mounted or hung by double chain.

X-TIGUA is certified to withstand temperatures between -30°C +45°C. For extreme environments such as steelworks or rolling mills, the VHT (Very High Temperature) version can operate at up to 70°C and the HT version up to 55°C.
