Hello Ladies and Gentlemen :o)


It is a privilage to be part of your community.

Does any body know where I can get a lampholder for a USHIO HPL 750/240v from please? Also, why do they have three pins?

Ship, if you pick up on this, where can I get a copy of your book, that is if you have finished it ;o)

I think the three pins has to do with the rating of the fixture. Source Four Jr's I believe have no hole for that pin because they are only rated up to 575w. The regular Source Four has the hole, because its cap is rated to 750w. It prevents you from installing the 750w lamp into something that wasn't designed to handle the heat it gives off.
