I know about the threading at the bottom.
However I had a bad experience with using the threading.
After I used it, there was a problem with the descending screw that tightens on the cameras cold shoe. It seemed to strip a little, or it warped the spring that is inside the assembly (I took it apart to try to fix it).

As a result I can't mount the light on a clod shoe anymore, as the screw won't descend enough to tighten. So since then I am weary about threading the light onto a stand.

SOny wanted a small fortune for the small piece to replace. It wasn't worth it.

If you don't use the threading, the cold shoe plate will brake, I have 2 HVL and both of them broke on me not once but twice, the threading seems to be stronger because it is much thicker than the thin plastic cold shoe plate, I like everything about his light except for a poor design mounting shoe.

Michael, can you compare the bottom part to see if the Sony is exactly match the the screw position of the comer? if so I have the bottom spare part that I can send you to replacce your sony, no fee from us :)

Exactly the same, I didn't buy the light from you but can I buy the replacement from you for my Sony light?

I'll take a look when I get home, but I am pretty sure that they'll match up.
Just so you know, I don't think that it's just the bottom part, but there is a small spring assembly of some kind inside which I think is the reason that the screw won't descend enough when the tightening dial is turned.

Khoi, I will have this part listed to the site for sale. I'm sending this piece to Michael to have to try first. We'll wait for his feedback later.

Or if you think this part will fix the issue, you can buy it here http://lacolorshop.com/products/item.asp?Id=cl. If you need to buy more than 1, let me know and we can work something out.

The replacement shoe works perfectly on my Sony HVL light, prompt shipping and it was very nice to do business with Taky.
Thank you very much.

Comer 1800 light is back in stock now!

Taky,

I can't get your site to come up?

Andy, I'm sorry the web hosting company seems to have problem with the SQL connections.

It is back up running now. Thanks

Taky, thanks for the replacement cold shoe for my Sony HVL light. As was mentioned earlier it fit perfectly and fixed my stripped thread problem.

Michael, I'm glad that piece fixes the problem for the Sony light. In case whoever's interested, I have this replacement part avaialble here at L.A. Color Shop
