ESQ Square Seriesclick for larger view
The ESQ Square is an AC-powered square PCB, populated with eleven high-brightness LEDs and encapsulated into transparent resin. It is available in Aluminum or Ceramic PCB choices. Aluminum being a better choice from price/performance stand point, but requires an isolation from the input mains voltage. The ceramic substrate material perfectly insulates from the input mains voltage, provides a more than 30% improvement in thermal dissipation over aluminum and features a reduction in weight. The robust design and strict quality control during production allows a life of more than 50,000 hours of continuous operation. The resin is environmentally safe, non-toxic, fire proof and retains its transparency for expected life of the product. Eliminating the need in a power supply, this module only requires an AC-power connection, considerably reducing the time to market of the finished product. At 95 lumens per watt, it is best suited for interior and exterior accent lighting, underwater and architectural applications.
