The Center of Attention.
The Right Combination of Aesthetics and Performance.

Centera from Simkar is the smart alternative for replacing outdated fluorescent technology found in older-style troffers and parabolic fixtures. This breakthrough technology offers a stunning architectural appearance while delivering flawless light distribution throughout the space. Centera’s fully luminous lens and high performance light sources deliver the right combination of aesthetics and illumination at a low cost of operation.

Centera provides uniform illumination over the entire face of the luminaire without annoying glare or light source imaging. The result is soft, even lighting across the working space, as well as adjacent vertical and horizontal surfaces. This eliminates shadows and dark cave effects associated with older parabolic luminaires, and reduces the number of fixtures needed for a given space without sacrificing occupant comfort.

Advanced Lens Technology
Simkar developed its high transmission lens using advanced resin technology that transmits greater, more uniform illumination. The result is superior illumination on all surfaces without imaging or shadowing, and at higher efficiencies. Traditional A12 lenses are less effective with light transmission, losing up to 35% within the fixture.

Choice of Light Sources
Centera is available with a choice of light sources to fit your lighting requirements. The LED engine provides an operating life of up to 80,000 hours (L70) and 26% greater energy savings over traditional light sources. Simkar uses the tightest binning possible to maintain the most precise color consistency. Other features include dimming from 5% to 100%, a CRI of 85, and a standard color temperature of 4100K, with 3000K or 3500K available.

T5HO, T5 and T8 linear fluorescent and twin-tube T5 compact fluorescent sources offer a cost-effective way to achieve superb illumination and longer life while reducing energy consumption. It embodies the best, most efficient ballast/lamp combinations and delivers up to 60,000 lifetime hours and 30% in energy savings compared to older fluorescent technology.

High Efficiency with Low Maintenance
All critical surfaces include post powder-coat paint with a 92% high reflectance finish. The sturdy hinged door frame includes positive cam latches and features toolless entry for easy installation and maintenance.

Its high efficiency and excellent light qualities will increase profitability through lower operating and maintenance costs. Better space illumination is also instrumental in raising employee productivity and job satisfaction.
