Mag 1D SST-90 build

I snagged one of PFs SST-90 evaluation pieces last month
and have been waiting for a purpose designed Mag heatsink

Member Britelumens, brought some out here

So now I have all the pieces, I threw everything together


All the necessary components



BTW the excellent host came from Wquiles :thumbsup:



The most important components



I removed the emitter from the star and managed to singe the emitter
a little, you can just about see the carbon around the metal surround



Everything assembled



To keep things simple, I chose to direct drive the emitter with an IMR 26500.
I had a KD OP Mag reflector on hand which I widened the opening using
a Dremel. This managed to flake some of the coating off around the openning Pt2



It lives !!!!



Not bad for a hack job


Important note .... I made the mistake of soldering the wires to the emitter
and then sticking the emitter to the heatsink first. I then realised
that once this was done there was no way I could solder the emitter
wires to the Mag switch inside the Mag body. This meant that I had
to solder on another set of wires to the switch and then solder that to
the emitter wires Pt3
I would have rather prefered to have no joints



The important question everyone wants to know is, how bright is this sucker?
With no way of taking actual measurements and just using my eye,
it is a tad brighter than my P7 Mag DD, this is from indoors on a white wall.
I will try and get some outdoor beamshots tomorrow.
The beam that this emitter produces, I can only describe as a HUGE hotspot
with tons of spill. No dark crosses or donuts but up close to a whitewall
you do see a very slight clover leaf.

There was some debate in Britelumens heatsink sales thread as to whether
his heatsink pedestal was high enough to focus correctly. I can confirm
that the heatsink will allow correct focus if you turn the Mag head all the
way down.

very nice.:candle:

outdoor beam shots compared to the P7 please.


ASAP.

Nice build!

My with IMR 26650 was also just a bit brighter than P7 &
quite blue.

Man, watching everyone try these things out is making me antsy. I've got several hosts to choose from, a hipCC in waiting, a heatsink on the way and no GJ bin SST-50.

Only a tat brighter than the P7.......seem like the other sst-90 builds. 1 Cell DD just cant give enought current on thoe emitters....ive we would only know the binning. :candle:

Any chance to take a tail cap Amp measurement? I think others were pulling only 5~6A on a IMR 26500. What does it pull on that KD Li-Ion you have pictured?

Very nice build dude :twothumbs

why if you only need the emitter you buy ssr-90 with star and not the sst90?

what current draw?(they are necessary thick wires to measure)


its hard get 9-10 amp with only 4.2v

we need very very low resistance and the springs have high resistance:
springs resistance +internal battery resistance+ switch resistance +wires resistance + body resistance+ contacts resistance must be < 4.2-3.6v(vled)/9 amp= 0.066 ohm

without springs and with highly pressure on the contacts I have obtained with battery at 4.23v more of 10 amps dd and around 8 amp with 5 modes circuit

10 amp direct drived bypassing the driver

at 10 amp i got more output than 2 x p7 +1 x q5 flashlights

great area of contact is necessary too for dont destroy the bottom of the battery with the high pressure necessary


maybe with four 1.2v batteries we can obtain easily high currents

Getting the SST instead of the SSR was an oversight on my part

With an AW IMR 26500 @ 4.05V, I am getting a little over 3A
I am charging up my KD D cell at the moment and will post the measurement
later on.

So far, I am a little disappointed at the current measurements

BUT

You are all going to have to excuse the terrible quality
of my beamshots. They where taken with a point and click
camera set at "moonlight" mode

First, a direct drive P7




Now the SST-90




I think a chimpanzee could have taken better photos

You were right, the SST-90 is "significantly" brighter :twothumbs

Is the reflector used in each host the same, or not?

Will

Yup .... both lights used the KD OP reflector

I do not remember the tint of the P7 but judging
by the photos it does seem to be a lot warmer than
the SST-90. Maybe that makes the SST-90 appear
brighter.

Hmm .... I have another direct drive P7 that has a cooler tint
I think I am going to have to do a couple more beamshots
to get a better comparison.

WOW great Mod! :tinfoil:

Very nice and interesting mod! :twothumbs
Any chance you can put an aspheric on it?
By the way how's the tint?

:wave:

maybe get 3 or 4, 14500s in there in an adapter for more voltage?

Thanks for posting. It is great to see people starting to experiment with these new led's. I am thinking of putting together a light with one of these but using a MAG 2D as the host and direct driving it with 2 KD D size Li Ion's or 2 18650's.

2 Li-ions will give you a voltage of 8.4V, your emitter is going to go

More beamshots, this time with a P7 cooler tint




The top is the SST-90 and the bottom is the P7

Just for you Freddy



Works well with an aspherical lens :thumbsup:


The emitter I have is an unknown bin and tint.
To my eyes it is a very cool white, which I prefer
