Luminus SBT-70 - Why don't I need one?

Hi all, hoping y’all can talk sense into this thing that I’ve become obsessed with. The Luminus SBT-70. It’s the one with a circular die face and no dome, a glass panel lies on top of the metal “window” in this emitter and it just looks incredible! It’s not very efficient, gobbles up amperage and makes lots of heat. But will run from 3-10A. I want to put one in a small light, probably running as a mule.

They’re $63 for the emitter alone!!!

Please, tell me why I DON’T need one!

Thanks, in advance, for all your help.

You don't need one Dale. I'm sorry to have to tell you that. You need a whole heap of them. Lots and lots. You know your going to be late for your footy match.

Seriously, killin me.

I’ve got this sweet lookin little Purple chopped AA mini mag heading my way that I think this would be freakin awesome in. I’m also talking to Sinner about a Titanium custom 18650 that would also be amazing with this unique emitter. I don’t have to have a gazillion hoggity million lumens. 600-700 would be really amazing in a very unique light at 4-5A. I can probably even carve out something in the form of a reflector that will make it perform better as a mule. I want to SEE this beauty inside the end of the light, if it’s a flood of daylight white, with a 90CRI, then so be it!

I had it in the shopping cart and that $63 price tag made me delete it. Again.

Figured I’d give y’all a chance to talk me out of it…

And then you tell me I need a bunch of em! I need your mill too.

It looks funny. It won’t play nice with a reflector to project a decent beam other than flood. I dunno it might do well with an aspheric as it is so flat…

It’s SO flat, you don’t have to de-dome it, you can fill the head of the light with copper where the reflector or optics once were, and let this gorgeous crittur sit right up under the glass and just glow! :slight_smile:

Maybe I should say my chopped mini mag is built to use a 14250 cell. :slight_smile:

Will a 14250 even light this thing up?

Won’t light it up much or for long. I’ve got a pair of em running an MT-G2 in a chopped aa mini mag made for a single AA cell, runs 1345 out the front and lights up a room without pointing it. Pretty neat and is a mule, big honkin emitter sitting under a gorgeous UCL that is invisible.

The data sheet claims 1A to 10.5A. Don’t know how much light 1A would give but it’ll light up.

Heheheheheh.

:smiley:

I read somewhere this Emitter is now showing up in some higher-end Car reflector headlights in place of HID bulbs, i just can’t remember where i read it.

I have plans to use one of these in an asheric. I don’t expect it to outperform similar setups. I’m more curious to see the round die through an aspheric. I would have played with one before now but was also put off by the price. I just bit the bullet.

What exactly is the benefit of having this led as a mule?

I am sorry. You should not buy it. You need to improve your karma by donating the money to The Naked Clowns charity.

But you do need it though. ;-)

Oh yes, you are allowed to buy it, there's just two conditions:

-it must be the daylight 90CRI version

-it must go into a nice aspheric, hard driven :cool:

It must be the 90CRI Daylight white, yes, but it can’t be hidden under an aspheric or TIR!

Mule, leaves the emitter sitting alone and exposed, nothing detracting from it’s simple elegance. I want to put it in a very small light. As a mule it has appeal due to it’s very flat nature, I could fill the head of the light with copper and have the emitter very close to the lens, maybe even against it. So you SEE this unique die and it cast’s it’s 120º radiance unobstructed. No beam to point, short distance illumination without aim. And yes, even as a defensive weapon…someone is in your face 400-500 lumens will definitely crimp their vision and possibly their plans, at the very least they wouldn’t clearly be able to see your choice of weapon being drawn. :slight_smile:

A ~2” light with 400 lumens, unique structure of light, unique emitter to go along with it. Nothing about this one is “normal”. Which is, of course, the appeal.

How about CREE COBs?
Also expensive and big, but with the efficiency you would want.
This Luminus does look beautiful though…
How big is the dye actually?

7mm square. I think it’s just like an sbt-90 with the corners cut off.

The SBT-70 will fit on a 20mm copper Noctigon made for the MT-G2…I think. I know the SST-90 fits, have done that.

It runs on one Li-ion cell, supposed to run on from 1 to 10.5A. So it could be tuned to run at pretty much whatever power level I desire and the supplied cell can provide.

The light on the right is what I want to put it in. These are made by TexasLumens, he’s the Master at creating lights…

The one on the left is for a single AA sized cell, the 14500. My plan for it is a triple XP-G2 for a friend of mine. I have one done the same and running a 3.04A Qlite that makes ~800 out the front lumens, like 811 on start and 763 at 30 seconds from an AW IMR14500. This size fits my hand perfectly, very easy to one hand operate the twisty and it’s a smooth natural motion…mode changes are super easy to accomplish.

The triple is floody, bright, and really a nice little light. So using a bigger emitter in mule is a spin-off…I have another of the single AA sized with an MT-G2 in it, running 2 of the 14250 cells. It makes 1345 OTF and is really cool, but that big dome caused it to be set pretty deep to clear the lens, with the SBT-70 I could stuff more heat sink under it. :slight_smile:

This little 14250 version might be difficult to operate, don’t know yet. There’s so little battery tube it might be a bit awkward in the hand, but it is small enough to easily fit in a watch pocket in jeans. :slight_smile:

The fully zoomed image threw an aspheric/fresnel would be round with this emitter. That alone would be worth it.

But you want 50 amps.

Admit it.

(Make a good dome light in the car.)
