My current one needs to be very near before the light at maximum power will have an effect on the subject.

Is it possible to get portable powered industrial grade construction lights?

Basically must be able to light up a spot from 10 metres or more.

I'm not able to recommend any light panels able to deliver what you want, but there is this Inverse Square Law on Light you need to understand.
http://en.wikipedia.org/wiki/Inverse-square_law


if your current single LED light panel able to light your subject at 2.5 meters, and if you want the same coverage on a subject that is further away from your light,
you will need FOUR same LED light panels when your subject is 5 meters away.
and need EIGHT same LED light panels when your subjects is 10 meters away.

so you can see, if a LED light panel has double the power output than your current LED light, you can only increase half a distance, not double it.
even if you can find a LED light that powerful as your request, I think most people will run away from you immediately.

Thanks for the tip, now can tell my vendor the minimum requirements. Also, you are half there as the lighting power is not only to catch people going away from me but also people coming my direction so using fixed lighting would be more safer then using flash that will fire out of a sudden and spook people thus causing safety concern. Again thanks.

Hmmm. What's your current light? So we have a point of comparison. What's your actual application? Specifics? E.g., how big is that spot? What will it be lighting? A spot to light up a small object vs a whole stage, very different. If you want an actual spot, you want something with focusable lenses, which rules out a panel, which tend to be diffused. A small spot, you can probably get by with a high powered LED torchlight, but dunno what your application is.

Without specifics, seems like a very high spec even for non-battery operated lights like the Jinbei EF-200 continuous LED (200W LED equiv to 2000W tungsten output).

Hmm... The closest product I can think of that is portable and batt operated but may or may not meet your spec is the Lowel GL-1. US$700 though ;p

--------------

Not many manufacturers give detailed info, and sometimes chinese makes like Jinbei are a tad optimistic. Thought it might be interesting to provide a point of comparison from the ARRI photometric calculator.

Assuming your current light gives you about 800lux @ 1m (since we don't know what your exposure is), and that is what you want at 10m, the Arri L7-DT (US$2845) could give you almost the equivalent with 767lux at 10m in spot mode (resulting exposure of ISO 200, f/3.41 1/48s). If the Jinbei EF-200 is anything close, it might be worth looking at? Shrug. Just some thoughts lah. I've also been on the lookout for a LED panel that is most bang for the buck;p
 

There are many lighting shops that sell led flood lights - your prob is that once into the 20-30w range thiese are eye cringing bright even at say 8-10ft away it is very hard to look at these lights but at that distance you may find that at iso 400 your fstop will be what may f2 at 1/30 The other problem you need ac supply of power or at very least an inverter power pack- cheapest will be abt $300. The flood should be around $200-$300. 10 meters is 33 feet you are need serious light power for that. I wish you luck because by the time you get something that meets your specs and can shoot say at decent stop and shitter speeds at reasonable iso you be having to spend a large amout. My guess is your budget is not that large.
 

That is a very elusive animal - have you considered the starkness of the light without diffuser ? Its like lighting with hot spot lights - very high contrast. Better to go with portable studio flash with dc power ala B1 and the china copies.
