Does it have a switch?. Can it be used outside the tank?

Yes. It has an on and off switch. It works outside the tank

Power supply seems to be 110v but it is described as a 220 volts input. Which is it? Can it be submerged into a pool for sanitation?

The little "wall-wort" power supply will work with ether 110 OR 220 as will many switching power supplies. "Submerged into a pool?" The light bar; YES as it is fed 12 volts (class 2 low voltage) and appears to be pretty well sealed. The power supply: NO!!! High voltage and water together is what engineers refer to as a "BAD IDEA" and could change your plans for a future.

Could this be used in a betta tank?

As long as it is underwater it should work. Keep in mind that it is a bright light, I have mine pointed down. I do not think you would enjoy look directly at the LED.

Would this be sufficient for a 20 gal planted tank?

Hi there. I have mine for a 40 gallon tank and it seems like enough light. I would think it should be sufficient for your 20 gallon tank.
