I was concerning. Light color skeptical. I had previously already tested other LED lamps, which then had a distinct green tinge. Still convinced me still the low power consumption compared to standard halogen lamps. Because of the good reviews I came across these bulbs and can only say: Absolutely Top! The light color is indeed almost a bit yellowish, but no comparison to my previous LED bulbs! After a short while you get used to the light and the brightness is absolutely great! From the 5 x 3.5W sense ago are much brighter than my 5 x 35W halogen. Will soon all GU10 lamps replace in my apartment with these LEDs.
