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.
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.
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?
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?
