Dialight, a leader in LED lighting technology, announced its innovation program has developed an industry leading solid state power supply with an expected life of 20 years. Dialight's new power supply technology guarantees long-life performance even in the most demanding applications. "Dialight has once again set the bar with our latest power supply design, providing our customers with reliable and efficient illumination for up to two decades in the harshest environments around the world," said Roy Burton, Dialight's Group Chief Executive. "Unexpected lighting failures and frequent bulb changes will become a thing of the past." The new power supply will debut on the company's award winning LED High Bay products for industrial and hazardous locations in Q2-2013 and will be integrated into additional Dialight fixture families this year. Dialight's in-house power supply development has already proven to be a significant benefit for its customers resulting in LED lighting fixtures with superior lumen-per-Watt efficiency, high power factor, low THD, various input supply options and high transient surge protection. With full quality control over every component within the electronic system, Dialight's designs are based on topologies and design techniques developed over several years. Efficiency and Lifetime With a power supply efficiency increase of 7% from previous designs, Dialight's new 20-year power supply will initially improve fixture lumen-per-Watt efficiency to over 110 lm/W surpassing competing LED fixtures and traditional lighting technologies alike. Compared to conventional HID lighting fixtures with bulbs that last 2 years between changes and which often fail unexpectedly due to extreme temperatures and shock or vibration, the new Dialight 20-year power supply will offer a tremendous total cost of ownership savings. Maintenance can be very costly to replace these lamps in hazardous environments. Bulb changes require permitting, scaffolding to be erected, processes to be shut down and multiple personnel for safety supervision, This new solid state power supply design is the latest innovation in Dialight's rapid technology development program that has turned out a number of first-to-market technologies, including the first UL Class I, Div. 2 hazardous location certified high output LED fixture to achieve an efficiency of over 100 lumens-per-Watt.
