Easy LED Replacement

Make LED replacement easy with Interchangeability standards poised to reduce cost and labor investment

By

 

Zhaga Consortium-certified lighting products will bear the organization’s logo to stand apart from conventional products.


How It Works
So far, Zhaga has released the first seven sets of standards, or books, covering a handful of lighting applications. The organization will continue to polish the standards as they receive feedback. Eventually, the organization plans to enlist a standards body such as IEC to maintain the finished books over the long term while Zhaga develops new standards for additional lighting applications.

Manufacturers can test their products according to one of the current books by partnering with one of only a few independent labs approved to evaluate Zhaga compliance.

The first round of testing concluded in spring 2012, resulting in certification for several LED modules and one complete luminaire, the IRiS P3LED downlight by Cooper Lighting, a founding member of the Consortium.

Providing at least 80 CRI and a color temperature of 3000K, the 3-inch luminaire can be replaced with any Book 3-compliant array featuring 9-millimeter LEDs without changing the heat sink or reflector.

“The use of interchangeable LED light engines enables an upgrade path, effectively future-proofing the luminaire and protecting the investment in LED technology,” explains Steven Pyshos, marketing manager for recessed products at Cooper Lighting. “Interchangeability builds confidence, accelerates adoption rates, and drives cost down.”

What’s Next?
Books for additional applications are likely, with at least some focus dedicated to linear applications, Swedberg says. The specifications are expected to gain steam as they earn market visibility and acceptance, though some suppliers and manufacturers will “push proprietary designs in an attempt to lock up market share while others embrace open standards,” Pyshos predicts. “There is room for both.”

Eventually, low-cost LED products that leverage highly optimized design and can be produced in high volumes will deliver “good enough performance at low costs,” Pyshos adds, noting that these luminaires will likely be replaced at the end of life. Long-lasting specification-grade luminaires, on the other hand, will benefit from the upgrade path enabled by the emerging standards.

“The projected life of the light engine is very long, while the pace of LED performance improvements is very rapid,” says Pyshos. “Based on the strides solid state lighting has made just in the past three years, it’s exciting to project how good the efficiency, color quality, and lumen maintenance will be in the years to come – all the more justification for a common interface to enable an upgrade path.”
