Single primary cell - most lumens?

AA, AAA, CR123, or smaller.

What puts out the most light for the cheapest price, regardless of runtime or build quality?

Guess I would have to say AA. AA's are so common that helps them on the price. AA NiMH can supply high and low power lights for a long time, AA Alkaline can supply low power lights for a long time.

Regardless of price... Well you can have someone design a high power driver to drive a Seoul P7 or Cree MC-E at full specs from a CR123 or a high discharge capable AA battery.

Is this just a hypothetical question or are you looking for a light to buy?

I think he wants cheapest price, regardless of runtime/quality.

The best places to look are DX, Kai. Buckle V5 for AAA, R2G2 for AA, 602c for RCR123, ... Those are the ones I can think of right now.

I would get the rc-n3 or the rc-c3 from DX or if u want to spend a little more get a q5 version from shiningbeam.com, as far as cr123 lights go. The rc-c3 is a single rc123 light and is a little cheaper and the rc-n3 is a great light can use either 1 cr123 or two AA's, it comes with an extension tube. The Q5 versions can put out quite a bit of light, or so I hear.
The Buckle Im pretty sure the cheapest/ brightest aaa light.
For a single AA light that is cheap and bright the rc-g2 is pretty good, again shiningbeam sells a slightly more expensive q5 version.
Although, I think if you are only getting one you should probably get the q5 rc-n3. It gives you the option of the rc123 which will be brighter than anythign a aa or aaa can muster plus you still have the option of using it in 2xAA mode. Also romisen is a pretty respectable brand, as far as budget lights go they are very solid. Plus it has a Glow in the Dark tail cap that I really like

I have the P4 version of the RC-C3 and the Q5 version of the RC-N3. Both are great lights.

The RC-C3 puts out a lot of light for such a small light.
