Quality Light Output

The Ex Tunnel Ray is the perfect choice of luminaire for applications that require:

  • Energy Efficiency

  • Glare Free High Quality White Light

  • High Colour Rendering Index

  • No Stroboscopic Effect

Robust, Solid
Body Design

Built on the backbone of the multi-award winning DLK, the Ex Tunnel Ray uses the same, proven solid body technology that allows it to be compact, lightweight, robust and completely resistant to vibrations.

  • Impact/Shock Proof

  • Chemicals Resistant

  • High Pressure Washable

  • Unaffected by Severe Temperature Variations

Product Benefits

Cool surface temperature

Solid state luminaires are designed to dissipate the heat generated by the LEDs. Due to this, the LED fittings have a much lower surface temperature than traditional HID equivalents.

Instant ON/OFF

LEDs do not require warm up. Instant on to 100% output translates to no downtime, improved safety and the ability to utilize sensor switching to significantly save energy.

No flickering

High Quality white light without stroboscopic flickering.

High IP rating - IP66

This product is high pressure washable.

Low Susceptibility to Vibration

This luminaire is designed to handle continuous exposure to vibration.

LONG useful operating LIFE (L70)

This luminaire’s life is rated at 50,000 hours to 70% residual light output.

3 years full/solid Warranty

All Coolon Industrial Products are backed by a Solid 3 Year Manufacturer’s Warranty.

Proudly Made In Australia

Coolon products are proudly designed and manufactured in Australia.
