pitch, neighbours don’t complain about late evening matches anymore.
The system has no “light spill” and only shows the light there where it is needed. Another advantage is, that, instead of the traditional MHD ( Metal Halide ) lighting, the LED lights can be switched ON and OFF and ON again, without having to wait for them to cool down first.
Ove Sörensen, Director of Sales & Business Development at Optogan addressed the potential of the DSF system. He said, “I am proud to present our great product here in Malta. Optogan Dynamic Sport Field Lighting in fact puts the sport into the spotlight. DSF doesn’t have to be only used for football fields, but is also excellent for many other purposes, like tennis, hockey, smaller play fields, as well as hotel chains having playing fields to control the spill of light and moreover, reducing the electricity bill! In other words, the DSF lighting is a very multifunctional product for lighting up areas, big or small”.
Pieter Bregman also highlighted the multi functionality of DSF and said, “Although the LED DSF lighting has been installed on a football pitch, it can be used in many ways! You can think of all kind of sports facilities big and small, car parking lots, local play grounds and ... well, you name it”.
Expected return on investment is around 5 years, dependable on the amount of evening matches or training sessions being played or held. “We have calculated for Luxol Sports Club, that the lighting will be used, at random, 3 hours per day and 5 days per week. Dynamically using the LED DSF Lighting will reduce electricity cost enormously. As the electricity prices are on the rise in Malta, savings made with this lighting system per year at Luxol Sports Club, will pay back the new LED DSF lighting system in approximately 5 years time,” added Pieter Bregman, Project Manager of The LightShop in B’Kara, Malta.

The order is scheduled for delivery by the end of 2012 and the expected revenues included in the company’s 2012 range is $925 million to $975 million.
GTAT believes the units will be used to produce sapphire for the mobile device market.
The company has said that tolerance requirements for mobile device sapphire screens are significantly lower than epi-ready surfaces in HB LED manufacturing and should reduce cycle times and consumable costs.
The firm has also indicated that it and several of its ASF customers have entered into evaluation agreements or are, in conjunction with fabrication partners, actively sampling ASF-grown sapphire screens for use in mobile and point of sale (POS) devices.
GTAT thinks the sapphire mobile device opportunity will contribute to a significant inflow of ASF orders in
