After looking at the add.> There is nothing ground breaking about a 3-way lamp. (Low-Med-High) it is just two lamps in one assembly.. One is the "LOW" the other is the "MEDIUM" and when you light 'em both you get "HIGH"
Think of the common 1156 Tail/turn lamp and it's LED equivlent. Exactly the same thing.. Low (Tail) Medium (Stop/Turn) High (Both).
The only thing new about this lamp is that nobody has built a 3-way for 120 volt use.. before it.. But this is not groundbreaking, It is a logical extension of existing designs.. I seriously doubt it can even get a patent.
