Review on JKLcom Candelabra Equivalent Decorative Non Dimmable by Sean Sheppard

These bulbs don't look like the 100 watt equivalent. I have them and some 60 watt lightbulbs in the same room. They appear to be about the same brightness. And there is no marking either on the bulbs themselves or on the box, so it is impossible to know for sure. I've tried to find the seller's contact information to ask about it, but it's nowhere to be found.
