Perfect and proper emergency lighting for the proposed tariff

I bought this solar lantern is not for use in camping but to send to relatives in Madagascar, a country with serious problems of access to lélectricité (and thus domestic lighting) that called over there the "shedding" (which can often last for two consecutive days).
So this lantern is emergency lighting and it must be said that the result is astonishing: it gives light enough to replace the light from conventional lighting (ceiling, wall light ...) say, without being a confirmed expert, it illuminates as a conventional 40-watt bulb, more despite the low prices we see a certain quality of materials used (apart from the wrist).
The only negative would be a concern of overheating: when you put the backup batteries (! Huge) while the solar battery is not empty so do not wait five minutes for the lantern base becomes hot, it is imperative to pay attention to check that the battery (rechargeable) of the lantern is completely emptied to insert the batteries in the "emergency".
I think me buy one or two in the coming months to send them to Madagascar.
