Who owns a Tek Light?

Yup, that's right.

It's confusing, though, because there's a difference between "extending" and "reaching".

For the most part, extention describes healthy polyp feeding/expansion behavior (there's a bit more to this where it gets confusing, but that's beyond the scope of this post, atm).

Polyp reaching is where, like jkhchris said, a polyp is physically stretching as much of its body as it can in order to acquire more light.

Hope that helps.
