I m thinking about a logo with a bulblight + exclamation mark. To avoid the overused round bulb shape, I thought the bulblight could look a little bit squary ( but still with soft rounded corners ). see pictures you can use here to get a suggested shape :
I prefer to have it almost vertically oriented, to make it straight as the exclamation mark. I don't have any requirement about colors. If you want to rotate it, don't do it by a lot of degree ( 15° ) to keep it straight and the default position of a bulblight.
I recommend a font like Petita in bold ( http://www.dafont.com/petita.font ) for the company name text. ( rounded font, but still with some sharp corners like in the b letter )
I also think the base metal tip of the bulb could look like a half circle, to make think ( but without obvious design such as Amazon ) to be a mouth / smile. make happyness felt by users without they realize it.
I suggest to look at my suggestion in the top link, I m just unable to make them with illustrator, but they are good guideline among what I would prefer. Of course, you are free to suggest the killing idea.
if you need more inspiration, I found only that link with a contest / review of lightbulb logos :
