Consider that with two blackstars instead of one you'd be spending 60% less and totally destroying the penetrators on PAR and effective coverage!! So better remove that Blackstar panel and replace 4 Blackstar UFO 135W. (720$ max) so you make the ultimate comparison FAIR.

Btw a Blackstar 135W only draws 80-90W so that'd be 360W tops against 520W of the penetrator.
I can see if that is your perspective from watching the grow on this forum, but please not that this is very incomplete, and I am not using the new Spectra lights which were totally redesigned.

My purpose it not to market other websites, so please forgive my posting a link to another site, but for those interested in following the comparrison, I have a thread still active on another forum. I discontinued this one due to a lack of participation all around, and time on my part.
