OK. I'll start off to say I'm not knocking their products. I have an EO-4 and an EO-9 and I'm very happy with both. I'm also considering a mini turbo head and IMR-9L assembly so I like Lumens Factory! But their products don't seem to be as bright as I'd expect from reading on here. I understand with the EO-4 there's only so much you can do with 1xLi-Ion and be efficient with something that relies on voltage like incans. But the 9V assemblies seem underpowered. The EO-9 which is "Extreme" output only makes 380 bulb lumens and draws just 2A. Now this isn't an incan vs. LED thing as It's not the output vs input I'm wondering about. Only 2A for the extreme output and 380 lumens? Their assembly for the Ultrafire WF500 also nuns on 2x18650 or 2x18500 and it's 630 lumens with just an HO designation. Why can't they do that with the D26 dropin. To get that level of output you need to use a D36 9V IMR dropin. To me the EO-9 should be 5-600 lumens as that seems to be ok on the WF and the IMR to be 1000. Maybe it's because they can't guarantee people will use 18650 or at least 18500s on the EO-9 as the hosts can also use 2x16340s which is still over 2C. So it's a safety thing for the masses? Once again not attacking LF as they make a great reasonably priced product and it's very nice to see a company still supporting us incan lovers just trying to figure out the strategy of why their products don't put out what is easily possible. Just look at the 1794!

Seems to me comparing the WF500 to a D26 drop in is apples to oranges.

They have to design them to run in a 6P on two 16340's.........They have to design for the minimum, unfortunately.

That's what I figured. Why is that an apples to oranges comparison? I've never seen a WF500 but it only looks slightly larger than a 6p running on the same batteries so it should be able to run at the same current

Ultrafire WF500 also runs on 2x18650 or 2x18500

Now you are into a different league vs a 6P. Ergo, apples to oranges. Now you are talking bored M3/M4 body territory. Given 18mm cells, the possibilities open up a bit.

In a stock 6P/G2, the most you can power an EO-4 with is a 17670. The EO-9, in a stock 9P/G3, is at most 2X17500. Not as much umph as 18mm cells.

The IMR9L powered by 2XIMR16340 is a nice pocket rocket. If your light is bored 18mm, IMR18350's give longer run time.

I find the 4xCR123 or 2X18650 lights to be unwieldy. I like the 3XCR123 or 2X18500 lights much more.

How accurate are LF heat warnings on assemblies like the IMR-9L? Is it a case of more than 10 mins continously and the assembly melts the solder or ruins the springs? Or more of a general warning that it gets really hot?

I just bought the SR-9L to shoehorn into a Pelican Saberlite. It's really nice and white and now rechargeable. Completely obliterates the original bulb and the LF assembly is cheaper too.
I would love to go a touch brighter but I need more than 10 minutes runtime.
