Below is a link to a comparison document that was written by Oxfam staff in 2013. A couple of other lights were added in 2013 but it does not include the NoKero units, which I only found out about this year.

The other option that I have seen is the Gravity Light which was a winner at the Innovation Challenge at last year's AidEx event in Brussels. This unit has no batteries or panels to break down. It could be ideal for poor communities and homes. I received a production prototype earlier this year and I think that the unit is now available.
