Can I use a 220V rated LED lamp on a 110V line?

Question

I am presuming the answer of this is no. (I haven't tried to use a 220V bulb from the supplier before but their supply of 110V or Wide Voltage bulbs is limited.)
E27 6W LED Maïs Lamp Koud Wit 750lm 6500K 69-SMD (AC 220V ~ 240V)
Is it safe to use this on a 110V power line?

Probably not, since it's an LED bulb; and while there seem to be very few details on the website, the link calls it out as 220-240V. Some "wide range" LED supplies work from 85V to 277V but this is almost certainly not one of those.
An old-fashioned incandescent 240V bulb will work fine on 120V, at roughly 1/4 power, and thus it will be dim and yellow (but it will also last a very long time.) But that is not what you linked.

NEC prohibits use of that junk
DealExtreme is all dangerous trash; it's the exact same cheap Cheese junkstream as AliExpress, BangGood, eBay and Amazon Marketplace.  Buying anything from them that touches mains power is simply out of the question.  NEC 110.2.
NEC also prohibits misapplication
Further, NEC 110.3(B) applies, which requires you to obey labeling and instructions. The labeling plainly says 220-240V.  So no.
