A while back I bought a Paterson Tungsten Studio Light from Speed Graphic. There were issues with the light. Immediately I noticed the aluminium Paterson label on the side had fallen and not horizontal. The plug socket on the back of the light was very wobbly. The e27 lamp holder was also wobbly so any bulbs fitted droop down. On the reflector, there is a hole through which an umbrella can be inserted. When this is fitted onto the light the holes do not align so an umbrella can only be inserted with the reflector not in position. I contacted Speed Graphic about these concerns who replied saying they will forward my concerns to Paterson. I did not hear back from either party. I am surprised by the shoddy quality of the light and am suspicious that it is a seconds item that they just wanted to get rid off. Because of this I cannot recommend Speed Graphic, Paterson or the Paterson Tungsten Studio Light at all.
