Q: Can you produce LED driver; if we give you the parameters?
' M& M. y0 u0 f4 QWe need LED drivers; 55 – 60 W and 70 – 75 W; 300 mA; from 28 to 42 V.这个驱动谁可以做/ E- _+ _- m. p1 m7 U
A: We need LED drivers; 55 – 60 W and 70 – 75 W; 300 mA; from 28 to 42 V,不太对吧,参数不对,搞错吧.

We use LED modules Samsung; 48 W (4 X 12 W) and 60 W (5 X 12 W); 230 V input voltage; 33 – 34 V Output voltage in one LED module 12 W.

We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
, {, I- K& r0 ~- @% oBut 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.: M, d: d/ F7 y
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.
% J. h: e" z9 }7 KTake attention, that we export lightings for several countries in Europe. : w R6 K+ A4 p4 t' A- M
Please, send me information how much will cost the transport for 10 pcs. samples to us.
