I don't believe LEDs are the best option for anything other than physical appearance. I have seen the Green Element EVO LED light do wonders at that depth, par wise. If you suspend it, you'd get a pretty even dispersion of light.
Thanks for the response, Freeman. If LED's are not the best option, what would you recommend as an alternative? I have done lots and lots of reading on the subject but there is so much conflicting information.
Also, i see that Beamswork do the Green Element EVO in sizes that would be appropriate for my 6', but I have no experience with this brand at all. How do they compare with the Sat+ and Finnex ranges?
