We had to have the connecting bars fabricated specifically for these lights. They do offer plenty of stability to the fixture, but most importantly ensure the proper spacing for PPFD. There are actually two different settings on each bar to make things even more flexible. I will have to look into shipping cost from the US and I'll send over some pricing for you. Thanks!They look solid lights @Nate @ Agro Lighting to be honest I only use my dimmers when I open me tent up! Don't want the neighbors seeing dots in there eyes for days!.. I've made my own modular setup... 240watt drivers tho so can alternate between strips and qb's... struggled to find those braces to spread them tho I could do with at least 4! ,if ya wanna dm me prices to UK be awesome cheers dude!..
