I previously ordered the Eurolite LED IP FL-50 COB UV, wich gives good results. But unfortunately these aren't available anymore. So I order these Eurolite LED IP FL-50 SMD UV. Very bad quality of light. These are cheaper but even then, 2 of these fixtures at 2 meters distance not even get the result of 1 Eurolite LED IP FL-50 SMD UV. Very dissatisfied. Product not recommended.
