To buy the Arc-LSH-P, or the LSHF-P w/Fraen optic

[luxlover]

Luxlover (Jeff) here again, with a new appeal to all of you!

Now that I have been convinced that, all things considered, an Arc-LSH-P is a little bit better than both the Arc-LSH-S and the SureFire L1, I need to ask what you people think of the LSHF-P, the version with the Fraen low profile optical element? Other than the extra light output in more of a spot pattern, as seen here.... http://store.yahoo.com/flashlight/arclsnfomo.html is there any difference between this, and the LSH-P?

You need to decide what you'll be using the light for. If it's for close-up work, you won't like the LSH-F.

I didn't even blink my eyes after I sent my post, and you have already replied. Amazing!

To access what you mean, I ask you if the Fraen optic version has a pattern similar to the Inova X1? That light has offered me my first experience with a pure spot pattern, and I can see this as a limitation of it's usefulness. I suppose that the LSHF-P has the same limitation?

I've never seen an X1 in person, so I can't comment. I actually have several LSH light with and without the Fraen optics. The LSH-F is useful if you want to see further in front of you without worry about a bunch of surrond light. I like them both, but for different purposes.

The ARC Fraen pattern is not at all like the X1. The X1 is kind of cool with the well defined beam, but the ARC still has good sidespill and is my favorite LS light.

I am beginning to get the picture. I think that I will look at a few more beam pictures of them side by side, and then make a decision based on what I see.

After careful viewing of a side by side shot of the beams of each LSH-P version, I agree with you that the X1 cannot be compared to either shot, since it has absolutely no side spill.

I just took this one from about 4 feet away. LSHF-P on the left & LSH-P right.

Here are some shots comparing the LSH-S to the LSHF-P:

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

Very nice. The LSHF-P has a large spot and still a lot of side spill. The LSH-P has a smaller spot and a lot of side spill. Your side by side shows a different relationship between the two, than the one on the ARC site here..... http://store.yahoo.com/flashlight/arclsnfomo.html However, your shot does show a greater light intensity at the center of the LSHF-P, just like the ARC shot. Good expeditious work, Terry.

Sean, your set of beam shots is the best I have seen. This has not been the first time I viewed your images. What most of us want in a lighting device is a light beam that has a prominent spot area of maximum brightness, is white, is undistorted, and has some side spill. It is your pictures that tell us the most about what a light will look like when we use it. They are impressive, very clear, and very convincing. You did a very smart thing taking shots outdoors, as well as indoors. The more scenarios you explore, the better your presentation of the character of each light you will be able to offer us.
Can a lens such as the Fraen optic alone, cause the increase of light intensity from 614 lux to 745 lux?

Sean, Nice beam shot pictures.Is that LSH-S same as LSH-P? I check ARC website and they re selling LSH (assume standard one), LSH-P, and LSHF-P. I am little confused about term on LSH.

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

I have both the LSH-P and the LSHF-P, maybe an older version, and my F-P is both brighter and throws a wider beam. Isn't there a wide- and narrow-beam version of the LSHF-P?

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

LSH means Arc Luxeon Star High-dome emitter.

LSH-S, LSH-ST and LS2 all mean the same thing, which is the standard version of the Arc LSH

LSH-P: The "P" means Premium emitter, usually "P" or "Q" rating. In english this usually means it's brighter, it can also mean brighter and whiter and more efficient emitter.

So the LSH-P cost more because the emitters are rare.

The LSH"F"-P (LSHF-P) is an Arc LSH-P with a Fraen "LP" optic that provides a more narrow beam angle and very little surround light. It gives more punch in the hot-spot at the expense of peripheral light.

The Arc4 uses a reflector instead of an optic. It produces a beam similar to the LSHF-P but with noticably more peripheral light.

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

Tovarish,

The "LHS" designation means Luxeon Star High (high as in "high dome"). ARC used to sell a light with an "LHL" (L as in "low dome") LED. It uses a low dome Luxeon Star LED emitter. It measures 4.8mm high from it's mounting tabs, and 6.02mm in diameter. This shape gives it more of a floodlight output. They don't make this anymore, but it is sold by others.
The new one, "LSH", measures 5.86mm high from it's mounting tabs, and 5.6mm in diameter. This shape gives it more of a spotlight output. That is all there is to it.

You beat me too it, you rascal! Between your detailed explanation (more useful), and my dimensional explanation (less useful), we are a match made in heaven. I even learned something......

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

Hello Jeff,

The Fraen optic will focus the beam of light into a tighter spot. Since Lux measures the brightest area of the center spot, the Lux reading for the LSHF-P will be higher.

I have both lights. I tend to find myself using the LSH-P most of the time. I find that for my use the extra spill is more of a benefit than increased throw. It has taken me a few months to decide this. I have been trading off back an forth, but (as of today) my favorite is the LSH-P.

Good luck with your choice.

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

Thank you SilverFox. You may be honored knowing that your post was the last one I read before ordering an LSH-P today. I should have it in my grubby hands by March 2nd.

I looked at some beam shots of the LSHF-P and the LSH-P, and decided that the sidespill on the LSH-P was more practical than the added intensity and narrower beam pattern of the LSHF-P. I bought the 2AA tailcap with it, since I chose the LSH-P because of it's AA battery capabilities.

Now I have a new project. Try to determine the most cost effective energy source. Will it be a rechargeable AA NiMH such as the Sanyo, with a capacity of 2,300 mAh? Or will it be a rechargeable AA lithium? Consider this..... An Energizer AA alkaline battery has a capacity of 2,850mAh. An Energizer CR123 battery has a capacity of 1,500mAh. Other than the ability to work well in cold temperature, a 10 year shelf life, and a small size, this battery has nothing special about it in the runtime per dollar category.

Any feedback on this?

Jeff

Re: To buy the Arc-LSH-P, or the LSHF-P w/Fraen op

Jeff, the only available rechargeable AA Lithium is the AA Li-ion which has a capacity of only about 700 mAh.
It has a voltage of 3.7 and needs a dedicated charger for safe use.

-The other AA Lithium (L91) is a 1.7v and is not rechargeable.

Hope you enjoy your new light. /ubbthreads/images/graemlins/cool.gif
