Imagine my surprise and great pleasure when I saw the little package in the mailbox from Croatia! :bigsmile:
These are Beautiful! And the anti-static bag they’re in is so professional, thank you very very much for leaving my 4 intact in the one piece board, just love it!
I’ll have to separate them, of course, but will do so one at a time as they are used.
Now to take pictures to commemorate this huge effort!
I took these numbers with a Mastech clamp meter at the emitter, via a short loop of 20ga wire between the negative driver lead and the star…light fully assembled with an XM-L2 U2 1A on a copper direct thermal path star and running without the bezel and reflector, spring bypasses top and bottom…
0.02A at 3.933 lumens
0.12A at 42.1935 lumens
0.99A at 409.86 lumens
4.82A at 1604.25 lumens
the meter varied on the .02A reading, going between .01 and .02. As well as between .11 and .12 on the low mode. This was using a Panasonic NCR18650PF cell at 4.20V, I tried the top end with a freshly charged Efest 35A and got the same number.
If you’re on the fence over whether or not to get this driver, just go for it!
I put one in a Fenix TK22 that was originally set up with a tail clicky for on/off and a side switch for modes. It was also rather anemic, with some 600 lumens. The LD-1 went in hard, as the original driver was a 2 board set-up, but now that it’s in I’m loving it! The tail clicky works all the modes in normal form, for use as a tactical light. The side clicky works the light as an e-switch normally would, provided power is on at the tail switch. So it’s the best of both worlds, with a lock-out for the side switch. And I gained a doubling of output to over 1200 lumens!
I Highly recommend this driver. :heart_eyes:
(also put one in a Sinner Ti light, this one was super easy to install and works like a champ on the tail switch.)
That kind of indevers should be supported, bravo
Whats your practise OP, direct PP payment or i should wait for an invoice?
Also, do you happen to have some spare 20mm Cu direct thermal pads?( will pay aditionaly ofc)
Waiting for your PM,
Regards!
I found a final home for my last LD-1 today. Picked up my first Sunwayman light, got it yesterday, the little Tomahawk C20C. While it’s UI wasn’t really bad and it had a nice feature or two, it was also only able to do 1.8A. So, I pulled it’s thin aluminum star with XM-L2 emitter and fitted a 20mm Noctigon equipped with an XP-G2 emitter. Now it has a tighter hot spot and runs 4.45A making 811 lumens out the front.
Love it when a plan comes together! :bigsmile: And it’s the size of a AA light, somehow it takes an 18650. I’ve got it stuffed with a 3200mAh Panasonic BD cell for the above numbers. Should last a good long while especially in the lower modes.
Driver is solidly grounded, has a bit of a brass sink soldered in to ground as well, and is potted in a good protective layer of Arctic Alumina Thermal Adhesive.
