Daisy chaining is when the light has an outlet on it, and you can chain multiple lights together on 1 main outlet. Although now I can not find it on the Vipar... I may have seen it on a different light. Nothing I can't just fix myself... Or the old fart I should say. Electrics are his specialty... This is my current monster cable.
I know the mars has 50% more wattage, but it is also 100% more cash... The Vipar comes out to $0.73/watt, and the Mars is $1.03/watt. Plus I am partial to Bridgelux LED. The Mars is great, I'm not challenging that, but the Vipar fits my build/budget better. I am going to think about it for a couple days, but I'm pretty sure I am going to grab 1, and then a 2nd when I can.
