It's probably this bulb:
105W 120V Spiral Medium Base
No idea if it would work in an aquarium hood. It is 11 1/2 inches long, 105W CFL, replacing a 500W incandescent bulb. If it replaces a 500W incandescent bulb, I can't see an aquarium hood handling that.
105W over a 10gallon tank, wow, 10.5WPG, imagine the algae I could grow!!
Where to buy it in Canada, no idea.
