I don't remember exactly how long the secondary burn light show was, but it was a long time for the F400. Maybe an hour. The fire and heat lasted much longer. It's posted in the wiki review of the Northern Idaho logs.

I hope to update the reviews this winter if time permits, though I'm a little cautious with a 3 cu ft box. There's room for a lot of logs in there and that could be a whole lot of btus.
