How many of you play around with your REFLECTORS?............

nottawhackjob · 2018-11-25T05:58:36.000Z

This blast from the past thread got me thinking of pulling out some of those Defiant Super Thrower (DST) flashes laying about and messing around with ’em again. I thought there were some interesting comments.

Any here reflector adjusting maniacs? :laughing:

I kinda surmise a lot of modders just stick in the new led and leave the reflectors alone as it can be a real PITA to mess around with the things. Unless you’re an Enderman who dreams of them or mods them like inhaling and exhaling.

Seems like aspherics these days have overtaken much of the reflector thrower’s past glamour.

Butt did we REALLY give them enough attention to begin with?

DST Monster thrower test for the Quad-DST project *UPDATE:* - BEAM SHOTS LED Flashlights – General Info

So below are three powerful throwers. On the left is a Tom-E modded BTU Shocker. In the middle is a specially modded Defiant Super Thrower. On the right is a powerful Olight SR90. The middle DST, is modded with a stacked-7135 Nanjg-105 driver driving a XM-L U2 Dedomed Emitter on a Noctigon at 5 amps using a Samsung 20R 18650 and fine adjusted focus, ) also will run on a 26650 with this body) I give who ever designed and build the DST reflector credit for they did a great job at designing the …

i play around with reflectors all the time. let a flashlight shine into it, arrange them in a shape and more

Hey watt are ya a standup flamedian or sumthing? :laughing:

I've never had good luck with reflectors...

We have a lot of Rodney Flasherfields on this forum.

Btw I’m surprised your face wasn’t ahem buried between those two beautiful mounds of Joy. Joyce. Whatever.

And we get no reflect.

About the only time Rodney got respect……….

You mean like this? Putting an Illuminations Machines LUM 55 in an OTR X5 Pro? Oh, wait, there isn’t a LUM 55, ok so it WAS a 77mm to begin with…

I sand em down and polish them by hand, recut the emitter opening to suit the emitter I use, file off the base to lower it, cut the rim off to lower it, whatever it needs. In this case, I cut the Illuminations Machines reflector to fit with a good pair of scissors.

nottawhackjob · 2018-11-25T18:25:37.000Z

Yeah that kinda messing around.

Btw how did that DST array pan out?

The beam convergence how to do it mechanicals has been a frequent back in my mind continuous musing.

DB_Custom · 2018-11-25T18:23:42.000Z

DST array?

DST array?

Ok maybe it wasn’t you butt IIRC someone was working on converging 3 or so DST’s into a single beam array contraption.

PS. Hah! Was thinking of DBSAR in the thread link above.

“…,is just a prototype test of a single head of the monster 4-DST head thrower project under construction that will use simmilar driver and emitter mods, thou will be attempting to push the amps higher and using 8 Samsung 20R’s in parallel.

- I will let you be the judge.”

The light in my Avatar is a modded Q8, I made a 4” dia head to go on top with 4 D4S Quad boards with the Angie optic and a 22mm reflector in the middle. A mix of emitters from XP-L HI and HD to Samsung LH351D in two tints and the center emitter is an SST-40 sliced and sealed, or de-domed and sealed. This starts at 25,427 lumens, is at 22,700 in 30 seconds. The Q8 driver is running the center SST-40 with 4 slaves running the quads.

The beam profile converges nicely, with a noticeable hot spot in the center from the reflectored emitter. I’ve always wondered myself how the multiple TIR’s or reflectors could look like a single emitter but somehow they do without having to alter the base plane.

Outstanding fabrication. Looks mean. :disguised_face:

Maybe this is sumthing Enderman can enLIGHTen us on. :student:

Edit: I think I figured out the answer to that after I took a nap. :laughing:

If you notice on the Q8 for example each ‘reflector’ converge together into 4 separate ‘cones’ with the center essentially meeting into one point. Even the old Skyrays with 3 x XML’s have the same configuration.

Conceivably you could fab the same with 4 DST reflector’s as well. The bitc* likely how to cut/slice each reflector accurately enough so that the central cone convergence meets as cleanly as the Q8’s. Prolly a jig is warranted.

But what about optics that have completely separated TIR’s? The beam still blends. I wasn’t sure how 4 such quad optics would work but it does.

Enderman · 2018-11-25T22:12:06.000Z

Yeah nottawhackjob is right, it’s just multiple cones that converge as the distance increases.
Same with separate TIRs, they don’t need to be joined.

Hmmm. Maybe those particular quad optic designs to begin with have hotspots diffuse enough that it only appears to converge into a decent focused blend? I have a quad optic flash due to arrive soon butt I can’t say from direct experience. Or maybe they have a slight inclining central leaning ‘cant’ that dismantling can verify.
