This thing visibly out-throws my TK70 at a 600m target. Actually i can barely make out the TK70 spot even with binos, but Dereelight DBS no issue at all.
I think the lux @ 1m only tells part of the story. Coz the TK70 got just 5% lower figures at the exact same spot which i measured the Dereelight DBS. And mind you i measure at 45-50 metres. This is because this is an aspheric....the focus is key.
Part of the reason could be that the TK70 throws out a huge cone of light. Hence through the air, the beam is quite visible as it is quite thick. This lowers the visibility of the hotspot at target. This phenomenon can be seen here.
DBS aspheric and then TK70 (last one is Sanmak 5200)
At 100k throw it would stomp the MPP-1 for sure. One light I still lack is a pure thrower, mainly because I really dont have a need for one. It would basically just be a toy for me. However, I wonder what kind of numbers my HID with 55W bulb with the 100W ballast/8.5" reflector would do in the throw category.
And one more question. If this light is such a great thrower, then why is it only about 250 lumens or so? I guess I don't undertand how it can be brighter than the TK70 as for lux reading at 1 meter. Please explain if you will.
If you get 4 DBS V3 aspherics, it would be 1000 lumens and have a hotspot that is only twice in diameter than the original one. It doesn't take much to reach 2200 lumens, just another 4 more DBS aspherics, but only increase of what 33% in diameter? (someone do the math pls)
Also, aspherics are a bit different from reflector setups. As you can see, the hotspot is even a wee wee bit bigger than the Solarforce MPP-1, but lux figure is twice as much.
In fact on a reflected ceiling bounce, the Solarforce MPP-1 registers 22.1 lux. The DBS aspheric registers a paltry 15.9 lux. Actually the DBS aspheric is like ~ 160 lumens OTF only. Thing is, nobody is going to do ceiling bounce or light up a big room with this. This is for outdoors use only.
Short arcs can be in the 2000 lumens range, but do 12 million cd and throw for several miles.
You can see the corona lighting up some parts beside the Crelant 7G5 hotspot. Also there is the spill light, but of course for such comparisons it does nothing.
Shoot. I think that this thread has convinced me that I need one. I have yet to get a good aspheric thrower so I may as well pull the trigger (ohhh my college student bank account :()
The Fenix TK70 is 3 XM-L’s right? The XM-L emitter has a surface brightness that is less than a XR-E. So having 3 XM-L’s doesn’t make the emitter surface any brighter.
Those 3 XM-L’s don’t hit the same spot. They make the spot larger. Throw is about lux and not lumens. The XM-L’s put out a larger wall of light but in any one spot the XR-E is brighter.
Take any of your XR-E lights that are driven at around 1A and take any of your XM-L lights that are driven close to 3A and shine them at a wall.
You will see that the center of the hotspot of the XR-E light is brighter than the center of the XM-L beam. The XM-L puts out more light (lumens) but the brightest part of the XR-E beam is brighter.
The brightest part of the beam controls throw because that’s all that’s left at that point.
For 1 single mode in max output (ie "tactical usage") and be able to use 2 cells (2 x 18350/16340/18650) it would be 1SM. Pls confirm with Alan of Dereelight.
The extension is EXT650, that makes it able to use 2 x 18650. It is usd12 additional, and is hard anodized.
With a 3SM multi voltage pill....and using a 4.08V TF Flames, i got 7.8 lux reflected.
With 2 x 18350, i got 9.7 lux reflected. So with a single 18650 it is still pretty bright.
