o ji valdyti su 1-10V dimeriu, nu toki pat naudoju liuminisc.lempoms su EVG 
1-10V balastu.

bet realiai cia gausis tas pats Curve dimeris, kuris buvo atachmente, tik 
galingesnis. O lempu jam vistiek nera. Visi parduoda tik juostos be 
draiverio. Gaunas kad turiu ieskoti ne lempos, o led sviestuvus, ir 
sviestuvas turi buti specialus, skirtas dimingus, be driverio. Nu kaip 
pirmam poste man ir rase anglas.
