Longevity

With approximately 70,000* hours of operational lifespan (16 years at 12 hours per night), the Pendant LED far surpasses HPS typical 24,000 hour lifespan and MH’s 10,000-16,000 hour lifespan. Since they lasts anywhere between 3 and 7 times longer, luminaires powered by the Pendant LED need to be replaced less often than HID luminaires, contributing to significantly reduced maintenance costs.
Light Source Lifespan

Philips Hadco designs for longevity with state-of-the-art software and technologies. Every product is designed and tested first with 3-dimensional software to ensure that the LED manufacturer’s specifications will be met prior to tooling up for production. Not only does this improve speed-to-market, but it also allows engineers to create optimal designs for thermal management which is critical to the life of LEDs.

A simple retrofit “solution” can quickly become more of a problem than a solution unless it is designed properly. Validation of the entire luminaire system design is critical to ensure that the LED manufacturer’s junction temperature limit is not exceeded.

Without proper thermal management, the promises of a long lifespan and delivered lumens from an LED luminaire cannot be achieved and pre-mature failure is eminent. Philips Hadco addresses these issues with innovative heat sinking and thermal management, designs that have been thoroughly tested ensuring the most reliable LED luminaire system available.

Why Dark Sky?

Philips Hadco’s goal is to be effective in stopping the adverse environmental impact on dark skies by providing a variety of products that will solve the effectiveness of night-time lighting. Philips Hadco is doing what it takes to make a difference.

Outdoor lighting regulations should promote lighting practices consistent with energy conservation, safety needs, and preservation of the natural light environment. The goals for all lighting regulations should be to use minimum light levels to reduce wasted light, glare, and trespass.

Per IESNA TM-15-07 Luminaire Classification System (LCS), these luminaires with the flat glass lens option produce 0º light in the UL and UH zones and less than 10º light in the FVH and BVH zones. See diagram below more information.

Full Cutoff
  • Light aimed towards the ground with none allowed to directly radiate over a 90º angle.
  • A maximum of 10% of the numeric value of the lamp lumen output radiates over an 80º angle.
  • No direct uplight.
  • Managed light flow that minimizes light trespass.
  • Efficient target lighting, no direct contribution to uplight.
