First of the function, go to both AC / DC and that is an advantage over the others, according to my estimation you are in the range of 10W halogen, have you installed in garden lights with an LED transformer. They have a Warmweißton, are a little more yellowish than my halogen 10W. Too bad that you even can see through the frosted glass all individuals SMD`s. There is at least one power saving available, at least I hope I do not have it measured. The delivery time took me by surprise, with 16 days, it went fairly quickly, had expected more.
