Note) The different points between LTA121C250F and LTD121GA0S are the below.
1) LTA121C250F lamp unit is different from LTD121GA0S.
2) The Metal PCB shield is added in LTA121C250F.
3) The rear structure is changed.
The Aluminum back sheet is removed and the Plastic frame design is different from LTD121GA0S.
The screw’s position of the PCB-GND and the lamp unit is different from LTD121GA0S.
There are slight differences. (Refer to page.3 rear dimensional outline in detail.)
4) LTA121C250F Operating temperature is wider than that of LTD121GA0S.
5) LTA121C250F total weight is different from LTD121GA0S. (Refer to page.1 mechanical specification.)
