Product Information
The Light & Motion Loc-Line Adapter 3/4" to 1/2" is a dedicated connector, part number 800-0203-A, that lets a 1/2" Loc-Line Sola light mount attach securely to 3/4" Loc-Line arms on an underwater camera housing. It is sold as the adapter only and does not include the Loc-Line arms or the light itself.
Who it is for
This adapter is built for underwater photographers and videographers who run thicker 3/4" Loc-Line arms on their housing because they move less than standard 1/2" Loc-Line in current or with longer arm setups, but who also want to run a compact Sola light with a 1/2" Loc-Line mount on that same rig. It bridges the two sizes so a 1/2" mount Sola light attaches securely to 3/4" Loc-Line arms.

Frequently Asked Questions
What is included with this Loc-Line adapter?
This listing includes only the adapter itself, part number 800-0203-A. It does not include 3/4" Loc-Line arms, 1/2" Loc-Line arms, or a Sola light. You will need to already own compatible 3/4" arms on your housing and a light with a 1/2" Loc-Line mount.
Will this adapter work with any light that has a Loc-Line mount?
It is designed specifically to mate a 1/2" Loc-Line mount, such as those found on compact Sola lights, to 3/4" Loc-Line arms. If your light's mount is a different size than 1/2", or your arms are not 3/4" Loc-Line, this adapter will not create a secure fit.
Do I need special arms already installed to use this adapter?
Yes. Your camera housing needs 3/4" Loc-Line arms or bases already attached before you add this adapter. The adapter's job is to step that 3/4" arm down to a 1/2" Loc-Line connection point for the light, not to supply the arms themselves.
Why would I use 3/4" Loc-Line arms instead of 1/2" Loc-Line?
Many underwater shooters prefer 3/4" Loc-Line over standard 1/2" because it moves less in current or when using longer arms. This adapter lets you keep 3/4" arms while still running a compact Sola light with a 1/2" Loc-Line mount.
