I haven't camped with mine yet (I have two) but have run them in the basement. My Goal Zero Sherpa 50+ ran the two of them at low light setting for about 14 hours straight. Even at the low setting they throw off a lot of light. Cords were super easy to unwind but more importantly easy to get back to the way they were when it was new!
They are a bit large for backpacking and combined with the power supply they may be more weight than you want to carry. I bought them for car and boat camping with the family so they'll be perfect. By the way, I have the Lighthouse Micro for backpacking...another home run for Goal Zero...AWESOME!
Ok so why not 5 stars? I read the specs and looked at the weight and size and thought they'd be perfect powered with my Goal Zero Venture 30...Nope, not compatible. I don't want to have to dig too deep to figure out what I need to run these. I ended up buying the Sherpa 50 to run them and am thrilled that I did cause the Sherpa 50 is AWESOME...but right up front it should be explicitly stated what will/wont power these things so other (less than observant people like me) will know what they're getting into without having to research it.
Keep up the good work Goal Zero and thank you BackCountry for the good price and great support!
