The Deft X of poor guy *UPDATE* 04/19 Attache beamshots #48

I agree... With aspheric lenses you should got slightly bigger readings but not much and with reflector flashlight lower readings.

Ah yes, forgot you said you had a zoom ability. That would indeed improve the accuracy of measurements at various shorter distances compared with a fixed focus lens tuned for long range performance.

I’d still encourage a long range test to reduce the margin of error on distance and am curious to see how the numbers shake down.

I was so impressed with this, I began experimenting with a really poor man’s collar. I had a couple of cheap parabolic reflectors from some old solar spotlights, so I cut the top off and proceeded to try and wrap my head around the concept. It seems like you get maximum results by focusing the light back on the emitter, it worked! Then I played with a couple of lenses from old binoculars and a large magnifying glass. Finding the right focal length may be a challenge but it is definitely doable.

Check out the Courui link in my signature, we’ve been looking at some cheap diy collar options. Up to now melon ballers seem to be a pretty good budget option :wink:

I wonder what would happen if you drilled about 3 holes in the collar, evenly spaced. Then focused three 445nm laser beams of say about 150mw each on the phosphor. Hmmmm

Now I enter the doubt …. :~
Anyone know how many meters are measured the 1000 kcds of the true Deft-x?
I know that Michael delivered a certificate with kcds and has its calibrated equipment…
I got a place with 20 mts free to measure the flashlight this weekend I will upload the results :wink:
I have a cheap lux meter, but with standard flashlights always gave me logical values very similar to those I read in the forums for example :

I saved these values when they were std, measured at 6 mts

Jacob A60 68 kcds
Thunite TN31 120kcds
Fenix tk75 (xml-t6) 98 kcds
Small sun C10s 65 kcds

I think they are within normal values :~

I think 20 meters is good enough.

It’s always good to verify readings under different parameters just to be sure. I’m sure your meter is fine though.

You didn’t by chance take a reading before installing the wavien collar? Would be very interesting to see just how much you gained by installing it correctly and fine tuning the focus.

I understand, I am going to make ….

Yes! that was a very important data :wink: without the collar was in 680-690 kcds, after install I was just above 1000 kcds! was already very happy :slight_smile: after a time (it always happens) I want more performance :evil: I tried with other leds, give more A, current draw without notice improvements…. so arm and disarm begin to notice changes without changing anything electronic :~ so I found that the collar was making a big difference :open_mouth:

Cool so you started at 680-690kcd & doubled that :open_mouth: Nice very nice :slight_smile:

You could upgrade the XP-G2 to an higher flux bin they come in as high as S3 i think thats 2 or 3 flux bin steps over your R5

Yes, I thought, but I will work it took me to leave it at that value and how sensitive is the focus, for that reason I will not do :frowning: maybe win some ended up losing much… besides collar is strongly glued and the glass is very delicate 0:)

Awesome, so if I understand that correctly.

690-1000kcd First installation of the collar.
1000-1300kcd Just tweaking the collar focus? Or are there additional electronic/led changes from the first figure?

Good stuff anyway, glad to seem some figures :slight_smile:

Ok i didn’t know it was glued, 1350kcd is more than enough anyway.

As i said my wish now is i want to see a 1000+kcd light with my own eyes :slight_smile:

Sorry for my bad English if you do not understand :frowning:

That’s right, jumps from 1000 kcds to 1350 Kcds only by the approach, I had taken as a reference the original height

Only one way to find out, it’s a cool idea!

Gotta be careful not to burn the phosphor though! :stuck_out_tongue:

Anyone who is looking for lenses on the cheap; Ebay has tons of old projector lenses since everyone has switched to digital. There are loads of old Slide projector lenses, cheap for disassembly.

Doubled its throw?? Nice project he did but it did NOT double the throw or CD’S,Not even close to that.

A guy on CPF just sold his certified by Michael @ 1032Kcd=2031m of throw. OP’s claims 1350Kcd=2323m of throw. Impressive although 292m of additional throw is not double! I know Michael tests his lights further than 6m away. We will never know which one throws more because these enthusiasts are worlds apart geographically and follow different standards of measurement. :wink:

Hi guys!

I bring some news :slight_smile:

I was doing the promised measurements in the place that I could get the results were:

At 6 mts: 1250 kcds
At 10 mts:1280 kcds
At 19 mts 1263 kcds

As you will see, is not that reason, in this place could not reach even 1300 KCDS :~ this is a place that is always closed and could observe many dust particles in the beam in the air…This will be the reason?
After these results to get home I measured again in the same place where I do all my measurements at 6 mts and though the batteries were not freshly charged for all tests in the other place well and everything was still barely above 1300 kcds :open_mouth: can influence the environment, in this manner, in the results?

Zoom out 1.05 meters in diameter to 4 mts

After a late night try taking pictures of the tower at 1600mts, that will light up the water tanks but had the vision obstructed by trees |(
this test had done last winter, now newly started the autumn here, despite this, take my old camera to try to take good pictures to share with you, I hope you like :slight_smile:

Look for more distant towers had sight according google earth are to 1.25 Km

Nice pics gaston :slight_smile:

I so want to play with something like that………fingers crossed it is in my future :wink:

A great post. My hat is off to you, sir.
