The barrel on the plug is too long and you will see a gap between the overmold on the plug and the control unit. Bad design, they are using cheap linear supply instead of universal input switcher. I am planning to swap it out on my unit. The linear is wasting 40% of the rated power sitting there doing nothing but keep the light on. California is banning sale of linears supplies next July.
Also, only Tunze dealer in MA is CRA which is NOT a LFS to me. I think it is a suprise that none of the LFS in Boston area is a Tunze dealer.
yeh I was just about to say that, Andy
