How does the new Aleph 1 compare in throw to the McLux PR-T head, assuming both are using the same convertor/current? Which will have longer throw? Beamshots comparing the two would be greatly appreciated..

PR-T versus Aleph 1

it is exactly the same as it uses the same reflective element.
or, to be exact, almost the same as this time it is a McGizmo-built relfelctor that is quite similar to the PR.
I think.

gregw,
Effectively, the PR-T and Aleph 1 are the same in terms of beam shape and output. The Aleph 1 does have a new reflector which seems to be brighter than the original PR reflectors so one might measure a higher lux on a meter. I did one bench test comparing a PR reflector with the McR-27 and the IMS 27 mm reflector. Judging by the highest recorded reading in this test of only one sample of each, the McR-27 came out on top with the IMS 27 next and then the PR. The total spread was around 20% with the IMS right betwen the two. My test was too crude and with just a single sample of each, highly suspect! Of course one can always replace the PR reflector with one of the McR-27's and this potential difference goes away.
The PR-T has an integral heat sink/ bulkhead (advantage).
The Aleph 1 has a removeable LE (advantage).
The Aleph 1 has a soda lime glass window with double sided AR coating (advantage).
The Aleph 1 has what I consider to be an improved window seal with the O-ring seating on an internal shoulder in the bore and the window compresed against it via a threaded bezel ring.
All told, I believe the Aleph 1 is an improvement on the PR and PR-T's but by incremental amounts. In actual use, one would be hard pressed to identify one over the other.
Beamshots would be like looking at twins! Lux measurements would be more telling but only applicable to the two packages tested and subject to the vaguries of finding the highest readings with moving the light meter around in the beam. I believe the McR-27 would prevail in most if not all cases but by how much?!?! /ubbthreads/images/graemlins/icon3.gif Although the differences might well be measurable and consistant, beyond bragging rights by numbers, in actual use and visual comparisons /ubbthreads/images/graemlins/thinking.gif .
EDIT: Just in from the marketing department: The new Aleph 1 has vast improvements over the PR and PR-T heads. The release of the Aleph 1 has rendered these earlier heads obsolete and any self respecting flashaholic would immediately stick their PR and PR-T heads on the shelf to make way for the new Aleph 1!!
Note: after receiving this information, the marketing department was given a carrot and instructed to hop away. /ubbthreads/images/graemlins/nana.gif

Flashlight,
Although my rabbit, Bugs, now has a bead on Bernhard, I have to agree with him for the most part! I have nothing but respect for DR. BK and his ability to "see clearly". /ubbthreads/images/graemlins/smile.gif I wonder if he uses flashlights to aid him. /ubbthreads/images/graemlins/thinking.gif

<font color="blue"> </font> Don,
I was wondering if the Aleph 2 that you are building for me will have the same window as the Aleph 1? I quote from "PR-T versus Aleph 1" above. "The Aleph 1 has a soda lime glass window with double sided AR coating (advantage)".
Don I also wanted to say I think your tutorial on the Aleph2 LE build is very good and easy to follow with excellent pics, I think I could follow it being the novice that I am /ubbthreads/images/graemlins/thumbsup.gif.
Thanks and keep-em bright in the night.

Bernard, In the universal language, /ubbthreads/images/graemlins/nana.gif
BareFootOne, All of the Alephs will have soda lime glass windows with both sides AR coated. The windows on the A1 &2 are 2mm thick and the A3 has a 3.3 mm thick window. Thanks for asking! /ubbthreads/images/graemlins/thumbsup.gif The dang windows were expensive enough that I might as well try to mention them! /ubbthreads/images/graemlins/icon15.gif
The brevity of this thread as well as life in general impell me to again use a universally understood image; /ubbthreads/images/graemlins/nana.gif

and a question: how scratch resistant is the exterior AR coating?
Bernhard,
It is apparently pretty hard and likely will scratch with the proper abrassive but is not too sensitive as to need pampering. When one considers the coatings on good eyeglasses as well as binoculars and other devices which have exposed windows or lenses, it would seem that any potential downside to partial removal or scratches is overwhelmed by the upside of the improved light transmission of the optic element being coated. /ubbthreads/images/graemlins/icon3.gif wait..... google search on Luxar......................
" Luxar® glass is the new leader in anti-reflection glass. Unlike many similar anti-reflective products which are soft coat, Luxar is a hard coat which allows for easier handling, longer shelf life and makes Luxar an excellent candidate for exterior applications that are subject to environmental stress and constant cleaning. Luxar's anti-reflective coating reduces the glare of uncoated glass from 8% to 0.5% when coated on both surfaces."
From the supplier of these specific windows, I have borrowed the following transmission graph:

yeah ... this is COOL STUFF and your marketing department /ubbthreads/images/graemlins/icon15.gif should have mentioned that in bold letters in every second post of yours as well as the increased efficiency of your McR-27 /ubbthreads/images/graemlins/whoopin.gif

Hi Don,
Thanks for the detailed info on the differences... /ubbthreads/images/graemlins/happy14.gif
Looks like I'll have to buy an Aleph 1 just to see the difference myself. /ubbthreads/images/graemlins/grinser2.gif

Bernhard,
I have a simple philosophy on my marketing strategy. I think talk is cheap and coming from me, on my stuff, suspect if not biased. I would prefer that *you* guys decide for your selves! Of course that means I do need to sell some of the lights and that means I have to make them. In fact, there's a couple LE's in the oven post curring right now that I need to get back to... /ubbthreads/images/graemlins/wink2.gif For what little it's worth, I am real happy with how these lights and their performance is turning out. I think the Aleph 2 and 3 compliment the Aleph 1 well and dare I say I think I might be in line for at least a few ataboys when it's all said and done. /ubbthreads/images/graemlins/blush.gif I know what I have developed here and that's really what's most important to me! /ubbthreads/images/graemlins/nana.gif
