With 3 single 1-watt LEDs to reach 290 lm luminous flux already seems very fantastic. In addition, the spotlight would then yes least energy class A ++ meet and not "only" A +. So somewhere there is a misprint ago 190 lm luminous flux were already a super value for this configuration; typically to be expected would be more 120-180 lm here. (A / A +)
Maybe the provider can clarify that yes Many Thanks! (For the time being only one 3 stars for implausible values, because for me the light power in lm or the efficiency in addition to the design and the electrical safety (CE conformity or VDE or GS mark) is the deciding factor.
