Do you have your clamp meter settings correct? DC voltage, range of at least 7+ Amps? Using a short, thick wire?
I’ve never heard of such things, so I’m not much help here.

I only got 4.8A with the same setup as yours. Posted it a few pages back.
EDIT:
Measured the current draw again using a fresh batt (VTC5) and was able to get 5.65A. Repeated the test and was able to get the same figure. With a resting voltage of 4.15V, I was able to get 5.53A.
Swib, technically the XP-L HI is not a de-domed emitter and it’s certainly a different beast than a de-domed XP-G2, so these will have different focus requirements. That inverted V shape is indeed a good indicator but 1 meter is entirely too close to reference point-of-focus… a really strong thrower has that point many times further out.
I like to view the emitter from the front, inside the reflector, and see how far back you have to get in order for the yellow phosphor to fill the reflector, that usually shows where the focus point is.
As far as determining just where to position the die surface in the reflector, without the schematic on the reflector it can be a hit-or-miss proposition and simply a hands-on trial basis to find what works best in a particular light.
Good luck!
Swib:I can’t measure the current with ramping, all I get is the double flash on my clamp meter.

Swib:Yes, I do believe that the centering ring isn’t the right height for proper focus. From what I’ve learned on here a dedomed led should have a focal point of about one meter like this
On the wall the focal point (where the black center dot disappears) is only a couple of inches with the GT mini.

Yeah it’s not my meter, I just can’t get the light to do anything but double flash when testing. Maybe I’m not fast enough with tapping the leads. I don’t have any problem on non-rampng lights. I’ll switch to the other mode group and try again today sometime.
keep the wire in place - No tapping
just operate with the sideswitch

It sure is hit and miss. I have a bag full of centering rings because I often sand off too much and start seeing the numbers go down on my meter.

:person_facepalming: I’m so used to measuring tail switch lights I didn’t even think of the side switch. Thank you.
swib try different batteries to rule out that atleast. weird one guy gets kcd in the 140 range u in 110… too much difference imo…
With the 30Q I use for testing I get 5.15 amps and with a slightly used VTC6 I get 5.48 amps and 120 kcd (with correction factor applied to my readings). Maybe it’s time to retire the old 30Q.
IMO the difference in output could be due to a higher Vf in this particular led. As I said it will find a good home where it will be appreciated.
Mine is still somewhere between the

^ Same here, but never got the overnight in NYC. Been in china the whole time. I check it a few times a day at this point. It’s like a sickness.

Try checking again, mine was in the same state as yours, but just updated (like, less than an hour ago) to “Arrived in New York”.

Thanks for that info Delta_V & congrats to you on some movement in your Mini GT tracking. :+1:

Teacher — I think you should go double check your mailbox—you might have missed it in there— The box was much smaller than I imagined it being—

I’m thinking it shipped by boat because I’ve had other orders from China placed on the 8th arrive by now.

I already did that my brother, in fact I broke out the magnifying glass as well as binoculars to double & triple check.
Still……. no joy. :cry: … .

Yep, either boat or a ‘trained bird’ that keeps getting lost. .
Don’t know if it helps, but I ordered mine on Aug 7, received it on Aug 20, this is Mid-Atlantic.

Yeah, I’m definitely a little disappointed. I hopped on the preorder, but I feel like I’d have gotten it by now if I had just ordered through BangGood instead. They even have coupons floating around to get it at the same price.
Mine was from Neil, not BG
