Exaggerated indication

I have the LED lamp as a replacement for a previously with an energy-saving lamp equipped outdoor light - used - with motion. The energy-saving lamp is not liked because they initially gave because of the relatively short duration only meager light and also the region below the light - because of the upright position lamp - has been insufficiently illuminated. The stated 810 lm - perfectly adequate for my purposes - can agree perhaps. The lamp may in any case not replace 100 W incandescent lamp, which would certainly give approximately 1200 lm.
I noticed that the lamp (s) themselves have no imprints. Manufacturing and performance specifications are completely absent. A certification mark (CE) is only glued provisionally. Whether this is justified, remains doubtful. In this respect, I think the use of the lamps for not entirely unproblematic.
