Broad-spectrum LEDs both produce photons the collodion can't see and also have significantly lower luminous efficiencies than monochromatic LEDs do. Both of these hurt you.
FWIW, my friend who got me into this just bought one of the 50W 450nm LED+lens+heatsink kits off eBay. We'll let you know how it goes when it gets here
On the topics of strobes, a lot of people say you need 10kJ to make this work. For whatever reason, I'm doing half-length portraits with just 400J.
