Testing Venue: PTT Jiffy Convenience Store at Srikaew, Nakorn Ratcharma Province
Scenario 1: Current installed system with 36 Watt. T8, 3 lamps per fixture
Scenario 2: Energy Saving System with 36 Watt. T8, 3 lamps per fixture
Scenario 3: Change to 28 Watt. T8, 3 lamps per fixture
1.Illuminance must achieve not less than 700 lux
2.Illuminance Uniformity must not less than 0.67 or 2:3
Conclusion: Both T8 with energy save system and T5 system met illuminance uniformity standard. However, the energy save system with power controller had achieved higher efficiency and yield higher energy saving according to the required time period and specific requirement.
