5D Mag - SST-90 - 95mm Aspheric - 9+amp build - Finished on 03/17/15 and beam shots are in Post #1

Very nice build so far, cant wait to see the other build as well

Subscribing to see what Texans use to heat their garage.

Interesting, especially as i might have a 6 d cell mag kicking about somewhere.

They got banned years ago, now you can only legally carry 4 cell mags over here iirc.

i might have to pool the 2bbl aspheric lens i have and get it done after seeing this :)

Hehehehehe!!! That is a seriously big lens you got there, I can’t wait to see some progress!!! Looking forward sir, looking forward…

Here is the popcorn, this is gonna be good! :heart_eyes:

I and my wife have watched your video just like a movie :heart_eyes: and there was a big smile on my face , i have almost 130mm Aspheric lens that i weren’t know what i could do with it, well now i know :smiley: , then i got shocked when i saw this Big black head with the 4 reflectors , what is that ? and from where you got it ?

subscribed…

Interesting. :slight_smile:
…but the LED needs to be 140mm away from the lens? Looks like the PVC piping might block some of the light if the LED is moved that far away?

9 amps, 3 miles, 4D Maglite, 140mm. You have my attention.

subscribed! this is going to be one epic build

Definitely interested in seeing this one come together! Looks epic! 8)
I had similar thoughts as Blinky1 about the narrow neck of the adapter possibly blocking some of the emission angle of the LED at such a long focal length?

Oh and you’re sure you don’t want to splurge on an SBT-70 for this build? Seems like the ideal LED for such a monster lens, nice round projected die! :bigsmile:

No heat. No AC either, so it’s either cold or hot.

That black head is a 5 mega and there’s a LED ZEP heat sink in it. It was 4xP7 but it will be 4 of the XHP70, maybe someday, when the mcpcbs and some 5000k or 5700k leds come out. It’s a build for a customer, just like this one is.

190mm focal length. I don’t know how it will come out. That’s part of the fun. I am going to try to incorporate a Wavien collar and see how that works. There may very well be an issue with the 2" diameter going to 4", but time will tell. What I might end up doing is to extend the 4" pipe, so that the 2" end just sits over the Maglite head, so the led would basically be into the 4" diameter to begin with. I don’t know how it’s going to go yet.

It was a thought, but I just want to see how much I can do with an SST-90. I just like those leds for some reason.

Better test run a scrap PVC pipe in the oven before you melt or disform (don’t think that’s a word) all your hard work

I know what you mean, I’m still tempted to build something around an sst-90 myself. It’s probably that juicy looking massive die! :slight_smile:

Awesome, looking forward to the build. :slight_smile:

Just wondering if the 3 li-ions in parallel would give 9A to the emitter. That might not be enough because with my SST-90, I had to supply 5.00V to drive it at 11A, so I’m assuming it’ll take more than 4.2V to push it to 9A, as well as losses in the wires and the linear driver.

I don't know. Guess I will have to test it out. The last one I did was with NiMH AA, but that would have been 4.8volt. It might not be enough. I might have to think about NiMH again. 4S/3P. It would be a complicated holder at best. Never had to get to 5 volt on the last one though. If I remember it was more than 4.2 though. Probably NiMH batteries will be the thing to go with.
