REVUE THOMMEN of Waldenburg, Switzerland has announced the future availability of the smaller and lighter HSL-800 Helicopter Searchlight for weight and power restricted aircraft operations such as single engine aircraft in the U.S. Law Enforcement market segment.

The HSL-800 is in the development stage at this time with anticipated availability in the 1st Quarter of 2012. The core design of the HSL-800 is very similar to the current HSL-1600 and users of both models of searchlights will find similar performance characteristics between them.

“The helicopter searchlight systems of our competitors are a composite of multiple components; the searchlight, power supplies, junction boxes, and slaving software interfaces,” stated Rudolf Iten, THOMMEN’s Vice Chairman and Director of Sales and Marketing. “The THOMMEN HSL-800 system is totally integrated within the searchlight itself, simplifying installation and operation and dramatically reducing installed weight for these weight critical aircraft,” Mr. Iten pointed out.

Revolutionary features include
• A new light source technology that allows the system to be significantly smaller and lighter than the competition.
• A “patent pending” IR filter design that is incorporated within the light assembly allowing deployment at mission airspeed with a range of 1000 meters using the 4° to 20° beam focus capability. Most competitors cannot offer IR in their smaller searchlights.
• A significant result of the single component system is a lighter installed weight PLUS a dramatic weight reduction when the searchlight system is removed for daylight operations.
• All solid state drives that deliver unparalleled smooth performance and contribute to the 5000 hr. MTBF reliability.
• All THOMMEN searchlights will be delivered with an EASA Form 1 Certificate of Airworthiness. No other manufacturer can offer a certified product.

“The one thing that THOMMEN brings to the searchlight industry that no other manufacturer can is the superior workmanship, quality and customer service that are inherent in the Swiss culture and is a paramount component in everything THOMMEN does,” stated Mr. Iten.
