磨砂是不是让光斑更均匀？

Hi all!

I just finished moding a FM Throwmaster reflector for use with a Diamond Dragon led from Arc Mania and I like it.

I installed it in a Brightlumens P7 heatsink so I can drive the ledhard! I am currently direct driving it from a 1 C AW li-Ion battery,anyone knows how much current is the led getting?

I am waiting on a 7135 driver to make a custom driver to run it at 2 amps with modes.

It seems to throw as good as the incandescent version with thereflector, here are some beamshots compared to another custom lights.

From left to right:

DSXOJ driven by a Triflupic on max with 2.5 throwmaster reflector

R2 WC driven by a flupic on max with a 50 x 35 mm aspheric from surplus shed

Diamond Dragon W5AP-NY-5Q direct driven by 1 Li-ion C in a throwmaster reflector.

R2 WC in a Jet II IBS on Max using Li-ion 123's.

As you can see the Diamond Dragon's hotspot is the smallest of them all even smaller than the aspheric! The throw is awesome!

I'll see if I can take some long range beamshots with it.

Thanks for looking!

还有一个改NC  EX10的


Nitecore EX10 with Diamond Dragon                                                                                                                                                                        Well, I now have an EX10 with a Diamond Dragon in it.

The Cree reflector ended up working better. The Diamond Dragon has alittle bit narrower angle (140 degrees) than the Golden Dragon Plus.Also, the gummy silicone dome is much larger with the Diamond Dragon,it's about the same diameter as the Cree dome, so it fit the Creereflector better. And it centers perfectly, since it's a very tight fitin the red holder.

Overall Impressions

The Good:
Excellent beam quality. No doughnut, no severe dark ring. Perfectlyuniform tint, unlike the slight variation in tone with the Cree rings,and the nasty yellow to purple spread of the GD+. The only majorartifact is at the outer edge of the beam from the crenelated bezel I'musing. (Russtang EX10 Ti Body).

The Bad:
Not really any brighter than the Q5 Cree. The hot spot is a little moreconcentrated with the Cree, but the beam from hot spot to spilltransition is very smooth. It does throw about as well as a Cree.Bascially the Diamond Dragon's beam is like a Seoul that throws like aCree, but with a less power consumption. 500mA is just not enough toget full brightness out of the Diamond Dragon (they are rated up to1400mA). But it would probably get too hot at anything higher.

The Ugly:
Runs hotter than the Cree, and significantly hotter than the GD+. Butnot dangerously so. Just noticeably warmer, heats up quick too, but Idid use Arctic Silver 5 for the Diamond Dragon. For the mod I did, it'**pensive. Not counting the cost of the Diamond Dragon, you need partsfrom TWO different EX10's (Cree and GD+ versions). Basically the LightEngine from the GD+ and the reflector from the Cree.

Overall, it fixes the main complaint I had with the my Cree EX10, theringy beam. The Diamond Dragon is a white wall hunter's best friend.While a Seoul with a McGizmo Reflector is probably the smoothest beamI've seen, the Diamond Dragon is also an impressive thrower. Best ofboth worlds.

是的 ! funder 兄說的對極 !!

因為產熱快且高 !

所以長時間點用, 建議找散熱佳的大燈頭來改 !

小弟的下一把想用 SF 舊款 KL3 有優良的散熱鰭片 !

現在在等能輸出 1400MA 的電路 !

以上是小弟的拙見給大哥參考 !
