• Simple operations as it fits into a standard household E26/E27 incandescent socket
• The PAR 38 LED is 5 inches wide by 4 inches with a light spread of about 12-13 inches when light is mounted 8-10" above water surface
• Focused Lumen Output

So, now I wonder is I really only need 1 PAR38 bulb?

The tank is only 15 deep and will house low light plants. If I go this route I'll use a track light pendant to mount the light so height adjustment or even adding a 2nd pendant is a non issue.

Because of the coverage, I think you will need 2 eventually and you can adjust the height when needed. A sign of too much light is algae growth faster than your plants

A lot of my clients use the cord from Ikea that looks like this:

Pretty stylish when dangling from the ceiling.
