Very poor fit

As mentioned by some Renz ions all lamps for common GU10 base are not suitable because the fit of the lamp is simply too large. From four ordered lamps has only one fit, the others went either not in the socket or have jammed, so I was afraid to break something. I have used in my ceiling lamp already many halogen spots, but such problems, I had never.

The one lamp that worked, has (hence 2 stars) if dazzling with 500lm a pretty impressive luminosity even for my personal taste.

My personal recommendation is the 300 LM variant of sebson, this is much cheaper and corresponds to my personal opinion also about 40W. The 500 lm are much brighter. Fitting problems in 300lm variant have this experience neither I nor other reviewers.
