how far does a 5w luxon thow?

im a total hack newbie to do it your self electronic's. wot im attempting to do is make a small powerfull torch\light of some sort to attach to the front of my compound bow so that i can hunt at night. Im hoping some one may be able to help me, ceeping in mind that i have size and weight restictions. :candle:

In general, Lux V's don't throw very well with the smaller reflectors. You may be better off looking into a Lux III light with a 27mm reflector if you want throw in a small package.

Depends upon what kind of arm it has .

Sorry couldnt resist. Actually I think it is dependant upon a lot of issues that will be explained better than I can. Using different lens like the Inova Tiros greatly increases throw, but decreases sidespill.

You should check out the 7w Golston .... pretty cheap and throws far. This could give you a baseline for what you want to build.... or it could be a solution !

A 7w Gaulstone? sorry my attempt at humer wot is it and wher would i find one? and roughly how much in aus dollars.

LuxeonV's can throw as long as the reflector is very large. LuxVs are 4 times the size of LuxIII's and need a larger reflector to focus it down to a spot. Think something the size of a Mag 2D head which is too large for your requirements. As morelight states, get a LuxeonIII with a 27mm reflector... that will punch a hole through the darkness and won't be too large to fit on your bow.

would you know roughly wot sort of distance id be looking at with a lux3?

How far you want to throw you light is proportional to the amount of money you can afford to throw away. Small wallet- 40 feet. 165 feet and more with a fat wallet (the wallet then becomes small.) It is hard to use less once you see how well a precision Lux V light works.

The right combination of parts will make a Lux V throw a lot more then you think it would. You are very noticeable when you turn on the light.

The Surefire C3 with the Turbo Head and Lux V Tower Module is quite an impressive white-beam light. It can be housed in a small SF C2 or 6P body but I like the long staff look. My C3 Frankenstein is not has heavy as it looks.

not as far as a luxIII.

I didn't know this was the ultimate throw thread. In that case a $3 LED laser will out throw a Lux III.

So all that in laymens terms please :touche:

Laymans terms, "You spent how much on that flashlight?"

nothing so far im going to my local electronics store and buying the bits so i figure about $30aus, probably a beter way to word my quirey is it the light source or the reflector that dictate the distance the beam will illouminate?or am i trying to re invent the wheel.

you can get excellent throw from a 5watt without spending much $$ by doing an Mr bulk SNIII direct drive clone. add a Downboy 917 ($20) if running with li-ion or BB 1000 if running with 2x C nmh. you can also do the same with 2x D mag and 8x AA or 6x AA holder.

aprox. costs

$18 = 2C mag host
$12 = hotlips C heatsink
$30 = Wbin
$10 = misc wire, Actic Alum
$12 = UCL lens

Cy, How's he supposed to mount a 2D Maglight on the front of a bow and still be able to shoot accurately ? I'd say he needs something the size of a one cell Fenix. The P1 has good throw, may even do the job on its own with a rechargeable.

the jet1 has great throw from what i hear.

opsss... didn't see the bow mount part.

I'm an avid bow hunter and have gone out many a time in pitch dark. but never had a desire for a bow mounted light.

probably the best solution a KL4 with E1E body running R123 li-ion. then fab a mount that mounts to bow weight.

Hmm, I stumble in and find an enormous amount of CPF-speak and a bewildered newbie trying to understand the "crazy talk" people have been saying.

What is it you're looking for? I get that you want to use a Luxeon to go bow-hunting, but what are your requirements in a light? It may just be simpler to use a store-bought solution, especially if you're a newbie to electronics. You'd also need to come up with a heatsink for the Luxeon because they create much more heat than the 5mm LEDs you're probably more familiar with. Let's also not forget the need for a reflector (or to machine one) and a battery case, and suddenly your expenses could go higher than it would be to just modify an existing light.

What I'm finding a little confusing here is-- are you looking for a thin beam of light that throws far, a wide beam that floods an area with light, or something a little in-between? Luxeon III (3w) lights tend to be better throwers, and Luxeon V (5w) lights tend to be pretty floody, although this isn't very firm -- it's really dependent on the reflector or lens you use with it. To paraphrase what everyone else said, Luxeon V lights need a bigger reflector to get the same kind of throwy beam that you'd get from a (smaller) Luxeon III light.

Or maybe we're all misunderstanding you -- are you familiar with the general floody beam characteristic of a LuxV and want to know how far you can expect a LuxV light like a Surefire L4 or L6 to throw?

For reference, you can get the 7w Golston and other cheap but decent lights on QualityChinaGoods.com. I've dealt with them before, and I can say I'm pleased with Dae's service.
