I wish I could get me one of those! I'd make sling for it so I could carry it on my back!

Not big enough
I think this one might come close to what I want =P

"finally".... the video was uploaded more than three years ago. 
Those 5mm LEDs are not very efficient... 2-3 lumens apiece I believe. A single modern high power LED could beat it in terms of light output.

Hehe.. somehow this thing was not built for function...
Other wise you might as well shove a car headlight into that tube, add a battery and a switch and be done wit it. Interestingly, performance would be better than that of those 500 5mm leds.

Yeah Benm, mostly for comical value
Thats an old video, but while on the subject, those LEDs are ancient indeed, I really don't see why they are still used for lighting applications today; other then bieng cheap as hell, can get 1000 of them for a few dollars.. not that it matters, brand name LED bulbs such as philips are still overpriced, where those use either those 5mm ones, or the SMD equivilant (albiet a bit more efficeint, it is no better.), they are really only good for indicator lights on equipment or appliances IMO.
A single SST-90 will blow away this 500 led light.

I think they've been phased out for most lighting applications. U used to see a lot of 'lightbulbs' that consisted of a number of 5mm leds (50-100 or so), but now most led bulbs have a sinlge emitter, or at most a few.
Perhaps the only benefit of the 5mm ones is that the power density is so low you can often use them without any heatsinking. Heatsinking is also easier when putting a lot of smaller smd leds on a plate, but most of those are pretty inefficient (50-70 lm/W) too.
I suppose efficiency doesnt matter that much with mains powered lamps, and they are still a lot better than incandescents, yet hardly require replacement.

the "Lights of America" brand is the brand that uses a ton of 5mm strawhat LEDs. Way to give LEDs a bad name, LoA. (Oh, and thanks for giving America a bad name too, although we had that to begin with. Also, I think LoA is made in China)

I speak for the rest of the lighting enthusiasts when I say: Lights of America is utter garbage. Most lamps die in a few weeks, and those that don't have severe lumen depreciation.
Oh, and they're dim to begin with
