Though the Trailblazer II's case does look a bit like the EOS, I don't think it is an EOS - rather, I think it is a Princeton Tec Quad.

If you check http://www.flashlightreviews.com/reviews_index/reviews_index_headlamps.htm the Quad is a very nice light, but not nearly as bright as the EOS. Brightguys.com sells it for about $28.95 - about the same price as the $29.50 at llbean.com.

The description says the Trailblazer II has "four LED bulbs", but the EOS only has one - though a very powerful one. It says the Trailblazer's low level lasts 150 hours, but the EOS low level is listed as lasting 60 hours. The Trailblazer says it has a red low-battery indicator, but the EOS doesn't have that.
