Hi all,
I've been searching around a bit for lighting to go along with my Hero2 GoPro. I have no plans of professional quality video, basically I am hoping for something reasonably compact (hence the compact camera) and don't have any plans for a canister light for this purpose.
I have found an option from Light For Me using two of their mini lights that are running triple XPG's, no optic and running off a single 18650.
Copied specs here:
The lighting system designed to make underwater videos:
Light-for-me underwater video set for GoPro Hero and GoPro HD Hero2 consists of:
Mini video torches tested to 100m.
Mini video torches are powered by a very popular battery 18650 Li-Ion available in online shops or on eBay.
One mini video torch requires one 18650 Li-Ion battery.
This got me to thinking.....:thinking:
Since I have recently acquired a couple of Trustfire TR-J1's (see other thread here: http://www.candlepowerforums.com/vb/showthread.php?337586-TrustFire-TR-J1) and they run off a single 18650 and according to our tests with the factory driver they give out the approx. current for max.current to an XPG....you can see where I am going here right!?!?!?
But....as I am no where near as technically minded or experienced as a lot of you guys on here I am putting this idea out there and hoping for some clarification on a couple of things.
I found that Cutter have a 20mm board with 3 XPG's on it (http://www.cutter.com.au/proddetail.php?prod=cut1228)which at first sounded like the perfect beast....until I see the specs that say: "series wired 8-10.5V required". Now with a single 18650 @ 3.7V I'm not that smart, but even my maths says that's not going to work. Or am I missing something??
Given that clearly Light For Me are running 3 XPG's off an 18650 how would this be done?
Also to you educated folk here; after the results shown and the analysis of the driver on the other thread about the TR-J1's do you think that this idea is plausible in anyway???
On a practicalities note: the internal diameter of the light head is 28mm and with removing the optic it frees up approx. 20mm for extra heat sinking, etc if deemed necessary.
OK....fire away
P.S. This is mostly targeted to the TR-J1's as I have them, but other host options/ideas are of course welcome.
