Did this GU10 LED lamp as Eratz for my ESL Osram Nano Twist with 7 Watt. Unfortunately, the Mengs is not brighter than the ESL in comparison, but darker. The color temperature could easily into the cooler, for me to "amber" for my taste. From light impression it comes very close to an ESL. Processing is Ok! On the lamp itself and the box is not a power rating of 5 watts to find. The recently purchased Lidl 3 Watt SMD LED reflector look lighter and produce a pleasant light. For confined spaces this Mengs are not bad, but is of the light output and light impression in my opinion, need for optimization. ;-)
