Today I went ahead and stacked two R100 resistors on top of the R020 sense resistor.
The current was bumped to 3.5A which is quite convincing, yet nowhere near where I would like it to be 
Aw that is a little low. Is that with bypassed springs also?
Yep that’s with bypasses.
By stacking the resistors I theoretically decreased the resistance by 25% and got 20% of actual current increase.
Keep in mind that the LD25 in my L2 came with an R020 resistor by default, not with an R025 like the LD29s.
My L2 from GB 1 year ago have different driver it should be LD29 but not the same as Jtm94 any idea how to pump the current ?
Should be this one?
!
!
Yep this is it.
Great review thank you. I am researching and learning for my second torch purchase. My first, Kinfire KO1B-T6, has convinced me these new-fangled LED torches are amazing.
So I’m thinking the new Convoy L2 Sand will make a more serious light and worthwhile upgrade for $36.99 plus 2 x 18650. Maybe a C8+ will be better for a beginner like me?
I do like more of a spreader and maybe I should make a white plastic diffuser for wide short range work.
An inductor is used in just about every switching regulator, and that’s a good thing. In a flashlight, the inductor is usually toriodal, it looks like a donut with wire wrapped around it. Every light in my (small-ish) collection uses an inductor to filter PWM pulses. the only lights I own that don’t use an inductor are a pair of Ultrafire XM-L zoomies I bought years ago, when I didn’t know any better.
It makes zero sense that this has an LD-25 or any other linear driver.
How are you powering it? 1s, or 2s? A linear driver would have to burn off ~50% of total power consumption (~10W) on high when powered by two LiIon batteries in series.
Either it has an LD-29 just like all the stock L2s over the last few years, just like it says on both the Bangood and Convoy product listings, or someone made a mistake during manufacturing and QA.
It’s a buck driver, or a variable FET driver.
Otherwise, it would burn instantly with 2S voltages.
Does the L2 sand have the same color like the S2+ sand?
And how many extension tubes can be sticked together to expand the size and runtime of the flashlight?
I got both lights and the L2’s color is exactly the same with the S2+ sand.
The extension tube simply screws onto the rear part of the original tube.
Banggood description said that New L2 came with driver LD-29 (21mm)
Now they stock with LD-25? How much mm it measure and there is space on the head bay for mount 21mm driver?
It’s the LD-2S and I believe all dimensions are the same otherwise.
You know, I am getting 908 meters range out of this bad boy!
I have modded mine with an A17dd-l and removed the centering ring, so the hotspot is a tad more tight!
An excellent thrower all around!
just wondering if there’s any difference (except for the colour, of course :p) between these two models:
I’ll buy one of the two using the m4dm4x promotion, but I’m just wondering if driver, fw version, accessories etc are just the same.
No, no difference (except for color).
I agree. As far as I know, both L2s are identical.
Though the new anodization colors are way better looking in my opinion
I know this is an old post, but I just came here to read up on the L2 I just ordered. Does it make sense to do mods to flashlights you’re reviewing, especially if you don’t mention it in the review?
