I never want to doubt anyone's veracity, but it does seem safe to say there will be no LEDs for the 130 or 250 anytime soon regardless of which information is correct.
Even taking the more optimistic information from Kev, if they don't even have a solution they like, we are probably talking a minimum of a year? More? That is if they ever decide they can make it work to their satisfaction.
So, for those of us wanting LEDs I think the answer basically is look elsewhere unless we are willing to wait a really long time for something that may or may not appear.
I'm happy with my recently installed Steves.
Even aside from the LED issue, if folks decide they like the E-series better, I think it makes sense to wait for it rather than buy the max now. The E-series appears to come with an open tank, which is a nonstarter to me. My kids would have all sorts of stuff in the tank before the water got in.
