Personally, i’d take this one:
No idea why anyone thought a 500m hid illuminator is necessary on your head, except china. Still looks awesome.
In case anyone needs convincing:
BAM! Alien transformer/ballast. Buy one and sent to James Cameron’s to put in next Prometheus movie. Much better than the tk45 and other lights they had in the first:
The ones like Stanley/Fatmax/Defiant XM-L that you get from Walmart/Home Depot does about 100k cd for a 4 incher stock.
If driven correctly and focussed decently, this would be in the ballpark of 400k cd.
PS. TN31 is 110-120k for 3-inch, and a modder pushed that to 240k cd which is also 3-inch. I think they used Diamond coated rhodo-plutonium reflectors.
Naise…. 13.5cm /5.3 inches ext diameter
It’s interesting to see spotlights transitioning into LEDs. I do rather that they use xml than a smaller LED. I know that Dolphin branded lights (in australia) have started to use LEDs, although it doesn’t seem to be cree, and it’s only 100 lumens.
3W XP-G, 5 inch? Beamshots inside. As you can see it ain’t pretty. The hotspot seems pretty big, but it’s a very close distance so probably it isn’f focussed yet.
Hahaha the wonders of Taobao and Aliexpress…I almost choked on my drink when I saw that headlamp…MOVE ASIDE ZEBRALIGHT :party:
The whole list of Zuke searchlights (LED + HID). They just rebrand the others….but price is pretty ok.
I’ll PM the aliexpress fella and see if i can get a discount.
Personally, if you ask me, it is impossible to focus a T6’s 120 deg beam with that kind of parabola (big and not deep) properly. All the flashaholic flashlight reflectors are much deeper. I know that a reflector’s depthj is not a factor in getting higher lux (diameter is), but just that…it’s probably not even nicely focussed with LEDs, if it’s even possible at all with that shallow a reflector with a XM-L’s 120 deg beam characteristic (non-optimised).
How about HIDs then? Dunno…but i do know that they are nicely focussed with the focal length about 1 inch into the reflector.
Too floody, i guess. But not too bad. It’s not a real wide angle shot, nor is it a telephoto shot. No EXIF unfortunately. Compare target distance/size of the guy vs the searchlight head size (8”). MAybe focal length = 50mm shot.

ZK2146. It says it’s shooting at a ~ 200m building. Well it’s definitely PSed, can’t be focussed on the light (in focus) and the target is still so clear.

xml output is still more or less sinusoid (as if lens isn’t there). Not as great for flat-ish reflector for putting light into the spot vs the flood as a filament point but that only makes the spot smaller, not dimmer (since if you look at a square from an angle, it becomes smaller, not dimmer).

So you are saying what I was also saying? Maybe you could rephrase that into layman terms. 
The ZK2146 rear blinker is nice. 
Here’s Kramer’s Defiant XM-L. 92mm reflector. Shallow reflector, but i think it’s still a wee bit deeper than this Zuke.
What I mean is that even with a shallow reflector, the light around the ends of the emitter will still be projected into the spot. If you plot a Cos curve, you can figure approx what percent of light can be focused into the spot by integrating to the angle created by the reflector (xml output is similar to this, just check cree doc on it). A shallower reflector will still be just as bright in the spot, just less % of the total output in and around that central area.
DX used to sell the Zuke 5W XP-G version, i think cheaper at 30-40 bucks during clearance. Some purchased it here but nobody gave any field report.
The Zuke 5W XP-G searchlight. About 5-6” ext dia. But it’s XP-G vs XM-L (smaller emitter)
Emailed the seller David Huang, lets see if i can get this bad boy and do some lux measurements. 
Wow, can’t wait for the April Fools Day “New Flashlights!” threads! I mean this is off the hook!
Late on this thread but here are pics of my 225MM XM-L. I dusted it off because I never use it. It throws like crazy but what would you expect with a head so large. Actually for the size of it, it doesn’t throw much better than my HD2010. Tonight I will do a beam test comparison and upload the pics.
The focusing on this reflector was engineered for the light source to be about 1 inch from the back.
That’s why the LED is so high into the reflector.
did you try recessing the led further back from the focal point ?
You must have a lot of light not even being focused by the reflector as it is.
Wow dchomak, that’s bad.
I am pretty familiar with the HIDs and the focus with such a large reflector and small “light source” is very sensitive. ie The large the reflector and smaller the emitting light source, the more sensitive things are. Ratio of emitting surface to reflector size.
A few folks bought the 5W XP-G version of the Zuke but no reports. Or maybe there were, i’ll do a search.
Thanks for the beamshots, i’ll try to analyze for you.
