Smaller SBT-90.2 light with Anduril - Anything on the horizon?

Not at all! I apologize for the way I worded that post, I was annoyed by how unrealistic Lumintop’s numbers were. It is possible that Lumintop’s throw is accurate, I just don’t know. Hopefully someone will get the X9L and post real measurements.

Most flashlights are a compromise in some way, hopefully X9L doesn’t have any major issues. Did you hear about the issues with Astrolux FT03S SBT-90.2? Astrolux used wires that were too thin, which increased resistance, and SBT-90.2 couldn’t pull enough current to get the output people were expecting. Some (all?) reflectors were worse than those in FT03, and throw dropped by 5% or more.

Can someone explain simply why the KR1 driver is better than the Lumintop X9L? …If that’s what the comparison is between. Or was the reference to K1 vs X9L?

I have multiple emisar/noctigon including the kr1, and you helped me make up my mind. i’m going with the X9L. I also have the fw21 pro and love the shape and form of the light. i love my kr1 too so its not an easy decision. I think even if the 163000 cd is over rated, it still has that larger reflector so it has to be worth something, and the fw21 pro is pocketable for me and the x9l is only 13mm longer.

The only thing i have no knowledge about, and is giving me apprehension, is the driver discussion from earlier posts.

Why is the CC driver better for this led than the FET? also, i’ve seen the loneoceans talked about, why is that driver so sought after?

sorry for my ignorance to this subject - the last time i asked about drivers i got blasted on BLF by people who think a google search explains the intricacies of these electronics.

Thank you

Is there anything you need to do to the light beside literally just swapping the LED? Like does the driver or anything need to be altered/enhanced/improved upon to make a sbt90 work in the KR1. It looks like from other posts the reflector needs to be teamed, but I mean do any electronic changes need to be made? Thank you in advance!

The constant current driver is not “the best driver for this emitter”. I don’t know if the KR1 driver has FET. Vinh claims to be using a different “Sky Lumen driver exclusive for SBT90” driver in KR1vn.

You need FET and a good battery to get the output that everyone buys SBT-90.2 for. SBT-90.2 limited to 5A is like buying a Lamborghini and limiting max speed to 55 MPH (90 km/h).

Having this monster in such a tiny host...yeah you need something like 5A CC. Vinh doesn’t say anywhere that all his wow builds can sustain output for seconds only before droping down like a brick...

I have sevarl tiny hosts like kr1 and sbt90.2 combo and it just doesn’t work as you think. This emitter in order to give what people are asking needs a lot of heatsinking.
CC will at least provide decent runtime and output over any FET in this type of host.

Just swap emitters and isolate 90.2 emitter around die. That’s it.

I guess I don’t really see the point of even having an SBT90.2 if the intention is to only use it at 5A or under. It’s very expensive and many other LEDs will perform similarly at 5A. Just kind of seems like it defeats the purpose, especially since the SBT90.2 isn’t particularly throwy (unless you crank it up to 20A to brute force the candela) and its tint is sickly green.

At the kind of currents you have to push through this thing to make it perform, I don’t think either of these hosts is ideal.

And Toykeeper just nailed it...

Thank you!

It’s green if compared to something less green. IMO it’s beam is nice and without any tint shifts in corona (at least NI40 version).

Have you seen dedomed SST-40? This is definition of green beam :smiley:

To be fair, I’m not a particularly huge fan of any Luminus LEDs as I find them all to be pretty green, even with the domes on (with the exception of the 3000K SST20). True that they don’t have much tint shift across the beam and that uniformity helps a little.

The SBT90.2 in my K30-GT measures duv at 0.0132. I got a bare LED from Neal that I dropped in a D80v2 and that one comes in at 0.0153. I haven’t seen a dedomed SST40 but if it’s worse than that, I’m not sure I want to.

The KR1 sbt90.2 driver is regulated upto 5A with direct drive. On turbo it gets as brigjt as your battery can push it

Which KR1 SBT-90.2 driver? Hank doesn’t sell KR1 with SBT-90.2. AFAIK there is only KR1vn from Vinh with “Sky Lumen driver exclusive for SBT90”.

I just ordered 7.5A CC and FET for turbo directly from Hank. A little playing with tools and it will be good to go.

I meant K1 driver. I think Hank likely uses the K1 or KR4 driver.

Vinh measured lumens and throw for X9L, throw is surprisingly close to spec. Not bad!

Stock X9L SBT90 @2s: 4850L, 160Kcd, 800m

Is this true because the graphs in this video shows it is regulated.

How did this driver work out for the sbt90? Did you put it in a kr1?

When the Loneocean driver be ready for X9L?
