Good acting ceramic package with printed information service, dimming etc. Strong also very "yellow" light genuine 2700 Kelvin personally hard for me at the border. Aperture fully ok at least equal to 35W halogen. Hammer is the dimming these 5 lights along with another 12watt ledTotal ~ I can 40W dim to zero !! the start lagging a bit (split second) behind the other after can not be considered a disadvantage.
