Borosilicate glass high-temperature LED tubular light ø133 for highly corrosive environments

The Leslie X-Heat tubular luminaire is designed to light up every detail of the most extreme industrial processes. It is durably resistant to acid vapours, splashes of very hot corrosive liquids, thermal shocks and vibrations.

The Leslie X-Heat luminaire can withstand the most extreme industrial processing conditions.

Chemical and sealing conditions

Highly corrosive or abrasive environments

Splashes of very hot liquids

Flame-resistant, inflammable

Oils & hydrocarbons

Dust and extreme grime

Very hot, humid or dry atmosphere

Washing with a high-pressure jet

Thermal, mechanical and electrical stresses

Permanent use at temperatures of up to 70°C

Thermal shocks

Repeated turning on and off

Mechanical impacts Intense and repetitive vibrations

Voltage surges up to 4 kV, power surges

Tried and tested extra-long life with intensive use at 70°C

Benefit from a sturdy, fully sealed housing thanks to high-temperature silicone seals tightened axially, specifically configured electronics and optimised temperature management. This LED tubular light reflects the full extent of our expertise in extreme environments, offering a reliable, durable option, even when used 24/7 at 70°C.

100% stainless steel and glass, guaranteeing unfailing chemical resistance

Benefit from outstanding durability and sturdiness, no matter how tough the conditions, thanks to a corrosion- and abrasion-proof housing in IK07 borosilicate glass, and reinforced stainless steel (304 or 316L) mechanical parts, including a cable gland as an option!

Ultimate sealing and durability

Forget fine dust, high-pressure jets, corrosive substances and the like. Thanks to its 3-seal system and uniform tightening with a central screw (the Screw© system), the housing remains firmly sealed, even when the temperature varies significantly. IP68, IP69K, everywhere and well into the future!

Reinforced industrial electronics

Even the very best housing cannot stand up to the potential effects of an at-risk network. With this in mind, Sammode has opted for the most reliable components available, designed to withstand electrical disturbance, voltage surges, extensive temperature variation and vibrations.

Divide your installed power by 3 with zero maintenance!

Unlike fluorescent bulbs, durable LEDs can be relied upon at high temperatures if duly calibrated and integrated. The results of our X-Heat models are spectacular: 100% light output from the second you hit the switch, equivalent to 2 x T8 tubes, while dividing your energy bills by 3!
