Well, the first impression when you show ... it's: "My god it's big!" ... Because compared to your standard bulb found in supermarkets or DIY stores, it seems really huge! But by comparing the brightness with, precisely, a light bulb equivalent to 150 W bought in a DIY store ... we retain two things: 1. Point rather positive, the light produced by the bulb is more neutral than the store 2. Point rather negative: this bulb is supposed to deliver a much higher power is 135 w since original ... while that of the DIY store is 32 w equivalent 150w ... The bulb of 135 w should produce light equivalent to about 600w ... so ... but it's nothing ... brightness, one beside the other, seems almost identical, there are only staining indicating a difference ... Disappointed, therefore, for this product, which, on paper, looks promising ... but, in fact, is optimistic about the real power ...
