Ok, this is not a bright light; it's only 10 watts.  If you're looking for a lot of light then this definitely isn't the right pond light for you.  But if you want to light up a waterfall or the underside of a cool rock, well, then this light is perfect!  As you can see from the picture above, it's sort of disk shaped, so it's easy to get it into areas where a normal full sized light wouldn't fit. 

It's fully submersible and comes with a 15 foot cord.  It does not come with its own transformer.

This is our most popular pond light!  Although it's worth noting that it's so popular because people tend to order a few at a time.  I'm guessing it's because they're creating a very tailored lighting look.
