Mount 'em Up
Received two lights, haven't got the batteries yet but have made mount/holder. Lights $152 each + Shipping came out ~$357.44 with shipping for two from
Aliexpress.com - Online Shopping for Electronics, Fashion, Home & Garden, Toys & Sports, Automobiles from China. Wholesale Product Snapshot Product name is 1PC Diving Flashlight ARCHON D32VR CREE XM-L U2 + XP-E N3 LED Most Powerful 32650 Battery Underwater Diving Led Torch I only gave them 3 stars because of multiple emails about verifying my address, not a deal breaker but irritation. All-in-all worked well. Couple of things to watch out for, batteries are not included but you can get them on eBay and other sites and DHL wants a signature when delivered so someone has to be available for signing.
Let you know how it works when I get batteries but box and presentation is very nice.
Now for the mount:
1/16" x 1"aluminium strip........Lowes
Cut piece 8" long
Use "D" flashlight battery or object of similar size and bend strip around form leaving legs of equal size with a gap for YS connector ball (Make a mark on the battery and roll across strip marking a full rotation on strip to approximate where to bend for legs-somehow worked out just right when the innertube was added; you can clamp the legs in a vcice and saw the excess off to even up))
3/8" SS cap screw or other SS 3/8" bolt (3/8" for YS connector hole) and 3/8" SS wing nut or loc nut
Innertube for thin road bike tire, your local bike shop will probably give you one that is punctured for free, it's a little less than 1" wide when flattened
Use enough bike innertube to protect light and help grip, slide it on 8" long formed piece of 1/16 x 1" aluminium strip
B&H has YS balls
Bigblue Sea & Sea Medium Arm Adapter DA008 B&H Photo Video Alternatively you could attach to Intova flex arm directly
Intova Flex Arm 18cm
No reason why you couldn't figure out how to attach to Loc-Line either, maybe make legs longer and put a 90° turn in the legs and screw into Loc-Line adapter.
I will spray everything flat black but left as is for better viewing of construction ☺
Will post video in a few months, getting packed up for extended trip to far Pacific.
