We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.2 d$ m2 s1 q+ a3 L* Y# D
But first we want to receive 5 pcs. 60 W + 5 pcs. 70 W samples. We will test them in laboratories. We have to be sure, that they cover the EC requirments.
