Two days ago we saw the hand-lamp in the hypermarket Selgros
http://selgros.ru/ru/maerkte/marktsuche/Kotelniki.asp (Novoryazanskoye road - 5 km from Moscow in the region). Cost about 350 rubles. Formally, it is to check the notes, but for our purposes will come down. Compilation - so yourself. It works on my two batteries, a sling for the brush. Unnamed option.
