Patricia,
Maybe if there is a "free trade zone" between Romania and Italy or Netherlands you can get Solarmeters.
Italy: Vito Marino ("Beat") from Samoa Club (+39) 0 25 5600659.
NL: Dennis Elbers from Alternatief (+31) 0 71 5820623
They both have Model 5.0 & 7.5 meters. And other EU distributors here:
http://www.solarmeter.com/distributor.html have 5.0's plus some other models.
At least then you could test lamps strength for yourself.
Also, closer to you, Lighttech in Hungary makes almost all the lamps for Hapro and many other companies. Contact Imre Krisztian
imrek@lighttech.hu and maybe he can advise what lamps to try for 9-12 min sessions.
