Some of you know this driver as the IO driver that Tom E uses in his Shocker mods. I bought five of these from Lightmalls and would like to report on them.
The bad news:
It does not come with the large terroid.
It does not do a true direct drive either.
The good news:
The contact board is the same size as the DRY driver
It’s a very easy fix so that it works as a true direct drive.
On the top of the driver (the part facing the contact board) you will find two small resistors marked r200 they are right next to each other. (Parallel to each other) and they are the only two that are. By simply bridging these two resistors you will get a true direct drive or at least incredibly close to it. I simply put a solder blob right over top of both of them.
I did this with my J-19 and running sony 50amp batteries I am now hitting 4,500 lumens. I have to say that I am completely blown away by this.
Very nice! This must be the one: LM 5A - 5 pack. This is the one we suspected may have been equal to the IOS or LCK-LED driver, and has the deceptive pictures, showing 2 different drivers.
To get 4500 lumens - is it the stock emitters, XM-L2's on aluminum? If so, on copper and heavier gauge LED wires you'd get better. Also no AR lens. Not sure if you wired springs either. On 1 Shocker, I got something like 5,400 lumens with domed emitters. But in a J19 using Powerizer cells -- wow, ultimate power...
I ordered this same five pack (SKU M0565) a while back and got the small toroid version. I didn’t realize until just now that it supports 1-3 LEDS. The ones Lightmalls shipped only give 3A, not 5A.
I added a R100 resister and got 4.6A. Now I’m going to have to run some tests with 3 emitters to find out if the ones they sent are even the right SKU. I placed orders for five different drivers, and not one was what I ordered.
Ordering from Lightmalls should evoke “caveat emptor”
Ohhh - that's right, I recall someone getting them, must have been you ouchy. I never did order one of these J19's. It's a better setup than a Shocker with 26650's, or 32650's. led4power's review was good, but doesn't tell me how it compares. So, I did a side by side comparison with the TF unprotected 32650 graph against HKJ's SONY 26650 cell, and the TF32650 beats it all the way - consistently getting higher voltage through the entire range, including near the beginning at .25 and 0.5 amp drain.
So, the TF unprotected 32650 is the cell to get, maybe even better than the Powerizer, and of course that's 5600 mAh over 3600 mAh. Wow...
