From my discussions with LED group buy and Rapid LED and Steve's, there isn't a 3 watt 420nm that can handle over 700ma that is readily available. You should actually run them at 600ma but they will still pulse to 700ma.
I was kinda bummed about this until I realized the PAR and PUR you get out of them even at this power.
Just FYI.
(I know someone is going to post a link to one that can handle more power, but, I did say readily available. That also means a reasonable cost for DIY)
