I am sorry to barge in here. I don't know much about lighting. I have two such bulbs with wide base that would not fit into any wall/ceiling/clamp-on sockets as well.
But I don't think standard clamp-on fixtures ( and recessed ceiling fixtures) are equipped to handle more than 40-60W without risks of overheating. Your 8" one may be an exception. Just a word of caution
Again I reiterate that I do not know much of lighting and this post may be uncalled for.
Good luck.
ps: I am interested in these lights too
