Need a 5watt in my Aleph 3

I think I can field this one.

What you should get, is a Lux5 in an Aleph-3 head. Some days I'm just clairvoyant.

Sorry, just being a goof. What's the question, exactly? If you "need" a lux5 in an Aleph 3, then I'm pretty sure that's what you should get!
 
On 2x123 you will need a LE with a BadBoy driver. The drive current can reasonably be chosen between 400 and 750mA, depending on your needs and the low mode.

Seriously though. Most get a 5W for the beam pattern. A wide beam pattern that is. It will put lots of light on the subject at the expense of throw. The problem with the 5W is the heat it generates and the runtime, or lack thereof.

If you get a decent bin 5W, say at least a V flux, you really don't need to drive the hell out of it to have a useful light. I actually have an A3 with an unspecified bin 5W and a BB500 light engine. This is a very useful light. Out to medium ranges, it has good throw and you can SEE what you are shining the light on because there is so much light. The heat from this combination is negligible. The light never gets more than warm. If you go to 700mA, you'll get more light at the expense of heat and runtime.

Just remember that the biggest and brightest is not always the best tool for the job. You should assess your needs and build accordingly.

Now, just some food for thought. If you are looking for a wider beam with reasonable throw, the Aleph II with a nice Lux III running at about 667mA is a very nice light and a good bit smaller than the A3 head. It also runs for a good long time on 2X123s.

If you're interested, I think I have a V3U emitter laying around on my bench someplace.
 
I thought i could get more throw out of a 5watt with the a3 head guess i was wrong i was looking for more throw out of the a3 any suggestions? i have a 3 watt twok with a downboy in it now. I want the most throw i can get out of this light /ubbthreads/images/graemlins/evilgrin07.gif /ubbthreads/images/graemlins/evilgrin07.gif
 
If throw is what you're looking for, what you have is about as good as it's going to get. The 5W will give you a bigger beam at the EXPENSE of throw.

You want MORE throw than that out of the A3? It already shoots a good 200 yards in the pitch dark. I know because my buddy uses one to check a plot from his stand and the plot is a good 200 paces from the stand.

At what bias is your Downboy set? If it is anywhere near 1A, you're there. If you want more throw, you'll need a M@g mod or something, but that won't be that much more throw.
 
mrdee3 ... here are comparison shots of a LuxIII and a LuxV as well as some classic lights with identical camera settings and assisiated lux reading (=throw):

Please note that the LuxV is overdriven at 917mA whereas the LuxIII is at spec at 917 mA.
The runtime of this LuxV will be significantly shorter than with the LuxIII and it will run much hotter, too.

Bernie,

Do you shower and sleep with a flashlight? /ubbthreads/images/graemlins/poke2.gif

Well...I'm glad I'm not the only one.
 
Tony ... yes, I sleep with a light when my girl isn't there /ubbthreads/images/graemlins/blush.gif ... but I don't shower with them as I am really not in the mood for anything in the morning at all /ubbthreads/images/graemlins/icon15.gif ...

BTW ... there's your "chopped" Exe-head in those pics /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/thumbsup.gif

where do i get that 4x123 body and how much more run time would that give me i know it probly wont change the throw but should double run time?
did not know this light was at the vary top as far as throw
thanks much
 
yes, runtime will be doubled ... or even a bit more since the converter runs more efficiently on higher voltages. Have a look at the sticky threads in the reviews forum for runtime graphs.

With 4x123 you'll need a DownBoy converter though and it won't run on 2x123 if you use a LuxV ... with a LuxIII it will though.

The body is a Balrog BE4 custom body. You can order a 3x123 body from DSpeck right now, it is called the UBH, or you can go with a VG3, but there's no 2-stage switch with this one.

The Aleph3 head is the best thrower in this class of light.

Here's a pic of an Aleph3 head on a brass UBH:

vs. the 4-cell version with the BE4:

vs. the 2-cell version using a SF E2e body:

my a3 is a complete light with a downboy 4-12 volt converter and a 2 stage tail but only has 2xcr123 body would love to have the 4x cr123 body
 
if you really want throw i've found like chop, that the mag is the way to go. I've got a mag 2C that i put a downboy1000 in and run it with 3x123 and a nice warm TVIJ emmitter. It out throws my aleph 3 at the same bias. In fact the throw difference is so great it's not a fair commparison. The Aleph three with lux3 is about as good as throw gets in the led world

bernie,

It's a shame that you got that EXe mod just before I started doing the mod with the chopped down McR20 reflector. If you're inclined to send it back to me, I'll fit it with a McR20 reflector and you could do a lux reading on it for comparison.
 
Yay! The banana slug is back!

Yeah right. Let me count up the number of folks who've sent me a Lux5 to build an LE. Hold on... tough math here. Carry the one, mutiply by Avagodro's number, take the cube root... subtract 16... ah here is it. ZERO.
