4 of the 9 lightbulbs check tested by MarketWatch gave a lumen output over 10% lower than their packaging claim. One of these was the Megaman 141401 LED spot, which measured an average lumen output of 22% lower. MarketWatch carried out a full test on 20 samples to see if this finding was confirmed.
Measurements were as follows (click for larger image):
Results from the 20 samples again saw a lower light output than claimed on the packaging by an average of 20%, and a measurement of one energy class lower. No lamp in the sample had a brightness of over 300 lm. Regulation 1194/2012 specifies a 10% tolerance limit for the average result of the batch.
MarketWatch has communicated these findings to Megaman, but has yet to receive a response.
