Arc LSH-P beam angle w/pics

[LEDagent]

I took these photos and wanted to post them mostly just for fun, but i also wanted you to see the unusuall beam spread.

I took this photo while cooking some steaks on our grill in the backyard. My backyard doesn't have any constant lighting, so it gets pretty dark without the shoplight turned on. I used the smoke comming from the vents of the grill to light up the beam spread of the LSH-P.

WHat's unusual (to me) about the LSH-P's beam angle was WHERE it spreads. All my other lights start to spread light right from the bezel, but the LSH-P starts it's spread abot 1/2" from the bezel.

Lastly, the picture is pretty much dead on with what i see. The beam on the grill surface looks dingy becuase the grill is dirty. Look at the beam spread and see how bluish/white (HID-like) the color is. I guess this is what sets a regualar LSH apart from an LSH-P.

Time for me to shut up and show the pictures:

Great shots! I think they also show the thing that we all try to explain about the LSH-P that seems difficult to grasp for those who don't own one, the throw. The center beam is very concentrated as is shown in the picture and really illustrates well why the High Dome Luxeon has that great throw that is absent in other LS lights. This is the main reason this light is my most used EDC now. I just used the LSH-P on a 2 day production that would have normally required my Surefire C2 to light stuff up at distance.

wow, those are great pics!

i've never seen beams captured like that before /ubbthreads/images/graemlins/thumbsup.gif

it is quite strange how the refractive properties of the nx05 work...
the 30mm optics are strange too, in that they appear to spread out from the center, as opposed to come out from the entire optic.

Thank you both.

like tsg said, i too have now made the LSH my EDC. I no longer use my beloved (yet heavily worn) E2 anymore. THe HA on the LSH is remarkeable...resisting any scratches that my pocket junk may try to cause. And, just like Peter Gransee said and designed, the recessed lens really helps, it has not recieved ANY scratches after MANY uses. For those of you that have seen my E2 pictures, you know that i don't treat my flashlights like museum peices...i use them. The Arc LSH-P is a great EDC light...i just wish it had a pocket clip. I hope the LS4 will have one.

YES!!!! I can't wait!

Great shots! It looks like a beam from a Star Trek phasor. /ubbthreads/images/graemlins/grin.gif

heres a pic of my LSH-ST Beam and some more /ubbthreads/images/graemlins/grin.gif

Cool beamshots LEDagent! You can see in the picture that the corona starts from the opposite side of the lens. You can also see how focused the beam has to be just to cast a decent spot.

I couldn't find any nx-05 datasheet around. From what I believe, after looking very carefully at the beam pattern from nx-05 in LEDAgent beautiful pic is likely to be either one of the two as the illustration below:

<font color="#666666"> Grey </font> area is our magical nx05 optics.
The <font color="blue"> Blue dome </font> below is our Royal Blue luxeon.
The upside Black dome is the dome inside the nx05 optics.
The darkblue in opaque is the Hotspot.
The angled blue spills is the explaination why light start to spread far from the bezel.

The darkblue hotspot should be angled abit as it grows larger as the distance increase, it shouldn't be rectangular as I drew in the pic. It's easier to draw it in regtangular but it doesn't matter as we are looking at the lightspills not the hotspot.

Sorry for the quick and dirty ugly pic, I hope someone could steer me right if I am wrong.

Cheers
Vince.

Since my Arc should be water proof, I couldn't resist to test it underwater in the pool. The beam looks really fantastic and due to the higher refractive index of water, the beam is more focused, compared to LEDagents pics

 

[this_is_nascar]

So, did it survive the water? Any condensation build-up on the inside of the lens?

 

[Rothrandir]

i think he would have told us if it didn't /ubbthreads/images/graemlins/grin.gif

nascar: i doubt it....my arc LSH-P is one of the lights i don't even hesitate to dunk. its been to a depth of at least 2 metres without any problems /ubbthreads/images/graemlins/wink.gif /ubbthreads/images/graemlins/thumbsup.gif

 

[BigMac]

That is so cool. Now I'm gonna have to try it. /ubbthreads/images/graemlins/cool.gif

 

[PeterB]

Nascar: No, I didn't have any problems /ubbthreads/images/graemlins/smile.gif. No water or condensation inside of the lens, and also the battery compartment was dry (I've tried the 123 and AA TSP's)
