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?
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.
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.
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.
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.
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.
