It has been brought to our attention that there needs to be some clarity as to what light fit what BtS arms, So here goes.
To the left above is the old model black 500 lumen and to the right above the new 1000 lumen model. Both of these lights work with the AL or UK arm. As seen here on our Facebook Page
UNI stands for universal mount but not totally in the literal sense of the word. It will work for any round lights that have a diameter of 3/4″ to 1 3/8″ max. like the Big Blue AL 1000WP for example shown below.
SOLA stands for the Lights and Motion Sola lights as seen here to the left the arm will slide into the light and connect with a single 10-32×1/4″ screw as seen here. this will not fit the older model light that had the 1/4-20 connection screw.
seen above, doesn’t use the same mounting solution as the standard Sola lights do. It has a curved contoured bottom, so if you are buying a arm for the Gobe light you need to use the YS version BtS arm and purchase the Gobi adapter for YS as seen here to the right.
Here is a list of compatable lights for this mount
VL5800P, VTL5000P, VL15000PM, VL25000P, AL1800WP, VTL2800P, VL2500P
There may be others now, but at the time I did the resurch this was it.
I hope this helps clear up any question that may of been unanswered.
Please comment if you have other lights that fit out arm we would love to here about it.
