Dongrui All-920

LED Flashlights – General Info 18650 Flashlights

So I bought this Dongrui All-920 (Q5) to use it as a mod host with an XP-G based on VFMaddict's posting about it. I received the light yesterday and have tested it out briefly. The light is pretty nice quality, although the battery tube is very very thin. It has double o-rings at the tailcap, space for double o-rings at the top (only came with 1), GITD o-ring in the bezel, GITD tailcap (I assume, but it hasn't glowed for me yet), a nice deep smooth reflector, and does not tailstand due to the protruding switch. The lanyard it comes with is better than the ones that came with my KD C8.

So I start testing the light and seeing what it can do and I'm like "HOLY CRAP"!!! This sucker can throw! (This is my first real thrower.) The hotspot is just slightly smaller than my Palight XP-G R5 and more defined (more focused) when viewed against a white wall at 20'. At one of my test locations I aim toward a barn across a field which is 600' away. This light lights up the entire side of the barn (guessing barn's height to be +/- 40' to 50'). The result looks very similar to my R5, although the R5 is a bit dimmer. (The R5 is driven at 1.4A.) I believe this light could easily do 1000'.

I checked tailcap currents with a 2400mAh Trustfire Flame at 3.92v at:

High: 1.96A
Low: 0.41A

I can't comment on heat dissipation as I was using it outside in 15 degree F temperature. I never felt the body get warm at all (and I did place it against my cheek to check).

Here are a couple beamshots. Top is the Dongrui, below is the Palight XP-G R5. Beamshots taken similar to my older beamshot post, but I backed up another 120'. Also, I said in that previous thread that the distance to the shed was 250'. I believe it is more like 200', might only be 150' (one of these days I'll measure that distance). So in these shots I'll estimate the distance to that shed as 300'. (Distance to that utility pole is about 60'; to the wooden fence post just to the left of the pole is about 120'.)

Dongrui:

Palight R5:

The beamshots aren't the greatest and I don't feel like is shows off the Dongrui like it should. The shed is lit up brighter by the Dongrui. I had to use my cheap Nikon camera that I hate set to "Night Landscape". When taking the photo it flashes the flash a couple times before taking the shot. I couldn't disable the flash in this mode. I think all the light in the foreground is from the flash. The Dongrui has a very dim (but usable) spill outside of the hotspot. I also have to apologize for the poor photo quality. I later found out that someone had switched the camera's setting to 640x480 resolution! (Man that ticked me off!)

So I don't know whether to mod this light or not! Maybe upgrade it to an R2? Maybe buy another (it's only $13.50) and keep one an XR-E and another an XP-G.

I'll end with a couple photos of the light:

EDIT 2-13-2012 - More Photos Added:

Reflector measurements:

(Reflector is in fact aluminum and the head has a step that the reflector sits in nicely.)

The head (rather nice chunk of aluminum):

Backside of driver and pill (notice the edge lifting up):

Topside Pill & Emitter:

EDIT - 3-26-2012:

Took some beamshots of various lights and so I thought I'd update this post.

Here is the Dongrui All-920 (150 to 200 feet to the shed):

(See what I've been meaning by large hotspot thrower with very useable spill?)

Next is my Super Tactics Q5 thrower (+/- 1.6A):

(You can barely see that the hotspot is smaller than the Dongrui's. Also, this one is more of a true cool white, while the Dongrui shows a little purple.)

Here is a mouse over (Dongrui = mouse out and Super Tactics =mouse over):

Does this light have any nicks or chips on the body or head etc?

3

I don't believe so. It looks pretty good and acceptable to me. You'll notice mine does not have any writing on it like the Manafont photos show (I prefer the writing to identify them).

Compared to the images on the Manafont pics can you see any other difference in terms of quality?

5

The Manafont pics show it off pretty well. (Note, I did not remove the pill for closer inspection.) Two other comments though:

1) The tailcap finish doesn't match the rest of the light. It's more dull looking. You kind of have to look close to see the difference, it's not that bad.

2) There is a spot on the driver where the edge of the circuit board is popped up. I can't really see what is going on here. The light did go off on me a few times and I found that if I unscrewed the head slightly it would pop back on. I assume this had to do with the driver issue and expect it to be any easy fix. I was able to screw & unscrew until I got it to where I had it screwed tightly and it stayed on.

I would really like some phostos of the pill without emitter. IF you plan to mod i'll appreciate the time to make a few shots at it.

7

Ok Budgeteer I'll try to remember, but I've got a couple mods ahead of this one and I'm slow to get my mods done so it might be awhile. I bet VFMaddict will get to his before me.

Bump. :P

9

Sorry Budgeteer still waiting for mine, only ordered about a week before CNY so don't expect it for another week or two judging by past years.

10

Dang! I'll wait. I like the body but if the pill is junky I'll skip it entirely. A "drilled" through pill i do not want.

11

I just hope that if it unfortunately has a hollow pill then there is room for maneuver with a penny or filled copper washer.

I've ordered a Jacob A60 as well so I'm feeling the same about that too.

12

Pretty interested on both about the pill.

13

Jacob A60 have anodized threads and nicer lanyard, but DONGRUI ALL-920 looks way better have a clip, GITD oring on head, is from manafont(less delay probably) and is cheaper

on the DX photos the light have a black hole on the center is normal for that kind of lights?

14

Ok, C8 tailcap does not thread on, just slips right over (too big). I don't own a 501b. Outer diameter of reflector is 41.70mm and length is 31.56mm. I took more photos and I'll try to post them tomorrow.

15

That one is sharpish-looking.

Solarforce M8 competitor, perhaps ? (Sans XM-L, of course)

Please report back on the Jacob - I've had that one in my cart for a week.

16

More photos added in original post. Sorry, I haven't taken the driver out to inspect the pill more closely.

My Dongrui and Jacob A60 have still not arrived. A60 not even dispatched yet.

18

Pill shots! Naked... both. Pretty please. :)

I just received one of the Ebay Super Tactics Q5 throwers. I plan on doing some comparing to the Dongrui All-920. And since Budgeteer asked so nicely I will see if I can get into the Dongrui's pill and get some photos.

I will say that so far I really like this Super Tactics light. Came well lubed with smooth threads and just has an overall nice feel to the build. The reflector is plastic (as expected). I did notice the aluminum pill feels very lightweight so I guess it's hollow. It does however thread really nicely into the "brass" collar and it seems to me it would have pretty decent thermal transfer once I apply thermal compound to those threads. I will post a comparison between the two, although I may not get any beamshots.

-Garry

P.S. The Super Tactics light came extremely fast! Ordered Feb 15th, received today Feb 27th!

For best focus, on my UltraOK Super Tactics, the pill needs to be slightly unscrewed from the collar, which makes it somewhat loose-fitting. So, I made a ring from a copper wire to fill the gap between the pill flange and collar, applied some thermal paste in that joint and screwed the pill down fast against that copper spacer.

Now I have perfect focus and the collar gets warmer.
