Heh, this probably belongs in the budget thread but....
Skyray SR5 approx 250-300 lumens/ $21 bucks
....8 cents per lumen I believe? 12.5 per dollar? Something like that.
Or those budget 1 dollar lights from ebay might be even better I guess. They are about 25-35 lumens for a buck.

Motomaster Eliminator 35 watt HID spotlight for $56.48 Canadian. 3500 lumens stock, 4400 lumens after a no cost ballast pot tweak.
Before tweak: 61.9 lumens per CDN dollar-1.61 cents per lumen.
After tweak: 77.9 lumens per CDN dollar-1.28 cents per lumen.

This light "claims" 900 lumen for 20.62$
In reality output of this light is probly more like 300-400 Max.
So 350 lumen/20$=17.5 L/$
IMO the best thing about these lumen's is they will fit in your pocket.

My latest homemade LED caving headlamp is 1050 lumens for NZ$47 (batteries not included), which is US$32, so 32.8 lm/$.
Interesting that the best performers above are HID and the $1.47 eBay lights.

My best
55W-DIY => 3500Lu / $120 = 29Lu/$
Stanley HID => 2500Lu / $70 = 35Lu/$
55W Halogen spotlight => 1000Lu / $20 = 50Lu/$
(*EDIT* I have never tested my HIDs, so I am figuring conservatively, and I have no idea what a 55W automotive H4 lamp emits, my 1000Lu estimation is not very accurate... I don't think)
My worst
SF-A2 => 85Lu / $159 = .53Lu/$
SF-M2 => 75Lu / $165 = .45Lu/$
SF-E2L => 110Lu / $149 = .73Lu/$
My biggest surprise
DX:903 => 155Lu / $9 = 17Lu/$
55W-DIY => 3500Lu / $120 = 29Lu/$
Stanley HID => 2500Lu / $70 = 35Lu/$
55W Halogen spotlight => 1000Lu / $20 = 50Lu/$

Re: Highest lumen output per cost ratio...
Litres per watt is probably the wrong way to measure light output, but might be interesting for size comparisons - HID would fall behind on that scale and my headlamp would do quite well. But halogen spotlights are probably closer to 24 lm/W.
Re: Highest lumen output per cost ratio...
Ok, I should've been more specific. Since this is an LED sub-forum I assumed the topic would be limited to discussions of LEDs. So that being said, I am interested in lumen/$ of just LEDs. Thx.

Re: Highest lumen output per cost ratio...
I had a bunch of typos... edited my post. I am not discussing Lumens / watt, we are discussing Lumens per dollar spent.
Lu = Lumens
Lu/$ = Lumens per $

Re: Highest lumen output per cost ratio...
In that case my $1 ebay light would win..... i guesstimate it to be 20 or so lumens when i compare it to my quark so that's 20 lumens a dollar!! :twothumbs

But perhaps mine doesn't count either, being homemade. Anyway, you're forgetting shipping.
Er, no. The symbol for lumens is lm (both letters lowercase).

It's a tie between the Bic lighter I found on a sidewalk and the free book of matches from a bar.

There's the Elektrolumens Blaster, the Next Generation. 1750 lumens @ $200 is 8.75 lm/$.

The Bic lighter is out; a candle flame is 13 lumens, and the lighter is ~$1. Even if you do the remove-the-restrictor/six-inch-flame trick, that's still only 20ish lumens.
You may be on to something with the matchbook though. You could get a box of 50 matchbooks for ~$1 and light all of them at the same time - that'd be a few hundred lumens for a dollar..
