There’s always that one weird Amutorch that was available as either two-emitter with reflectors, or a weird quad (spaced wide, and with aspheric lens)
thanks thats the one I was looking for
pic is a link
You must only mean 1 special case of 2 emitters. Do you mean when there are 2 identical side by side emitters? Because there are a whole lot of lights with a pair of different emitters.
1 white and 1 aux color is pretty common. So is 1 flood and 1 throw. Often an emitters points forward while the other is an anglehead so the light can be both. Having a pair of emitters greatly increases the flexibility of the flashlight and it is pretty popular.
I meant primary not aux.
Also most of the lights mentioned are two single emitters in one unit.
I had to make this one myself. 
See where you’re going and where you’ve been—simultaneously! And at the same time!
Yes, it works! The battery carriers are back to back and insulated from each other.
Not space-efficient.
1 emitter, you can size the head/reflector up/down as you want.
3, 4, others, you size the head up/down, and stuff the LEDs regularly in a circle.
5 would be wasteful (quincunx shape) unless the center LED’s reflector/lens is reeeeeally small.
2 is by necessity a 2:1 rectangle. If you stick ’em in a circular head, there’s wasted blank space above/below the side-by-side LEDs.
Unless you want to buy a 2-emitter light at the Darth Mall.
Only reasonable 2-emitter light would be with 2 cells side-by-side as well. And those are all weirdo designs, so it’s not surprising it’s rare.
So, from Algebra 101, we can conclude if A=B and B=C then A must equal C no?
Similarly , if LB taught you, then who taught LB? Its a mystery . LOL
If you go back far enough, you will find a caveman holding what seems like a flashlight. On it will read “Ever Light Bringer Edy.”
exactly
That would be two single emitter lights in one.
In a pinch, I would “palm” a headlamp, so youse can use a D25 like that.
The Darth Mall.
I think that’s your best one yet.
I chuckled, and I don’t even like Star Track.
That’s where I got my last light.
Turned it on, almost got a 2nd bellybutton.
Dr Smith is displeased.
The guy with the elf ears who flashes gang signs? I thought his name was Dr. Spork.
Dr. Spork with his 1-emitter light that he got at the Darth Mall (in the Star Track Universe.)
One of the first pop can flooders, if not the first, the Niwalker MM15 2 x MT-G2, is a two emitter light. I waited until November, 2014 to latch onto it. The review by Selfbuilt mesmerized me for weeks. So many happy memories!
