The only reason for doing this would be because these are more common, correct? Would it be more cheaper? How would I "regulate" it through a "regulator IC"? I don't understand what these terms mean.dear you can also use 9V or 12V transformer (which one is easly available in market) then regulate it though a regulator IC.
You can control both devices through switches.
Thanks for your help, I got more questions though!1 - 0-4.5v you say? So if I power the bulb using 3.5V, or 1V, it would still work? Would the light just be dimmer?
Yes..you can use it in the way you mentioned but use a bulb equal to the volatge available from the transformor for better brightness. Too be very carefull while handling AC mains, and sugession from "KJ6EAD" may be considered.2 - Can I use the transformer I already have, and just connect the wire from the mains to the prongs? Is there a better solution to do this, like a really cheap and small transformer you could recommend that is different from the one I already have?
Yes..you may do as shown in this picture.3 - How can I make it so there is a port on the edge of the base instead of having one big long wire? I want it to be like this: **broken link removed**
To do this use individual swicthes for both. One swicthes the Motor, and other swicthes the Lamp. Simple.4 - Last thing, is it possible to have some sort of button or switch on the outside of the plastic base which would give me control over the following?:
Option 1: Light on / Pump off
Option 2: Light on / Pump on
Option 3: Light off / Pump on
Option 4: Light off / Pump off
It's very unwise to use a hazardous voltage in water, especially where it's completely unnecessary. Just use a 12 VDC submersible pump and a 12 V bulb. These are readily available.
How? What is the little port thing called?Yes..you may do as shown in this picture.
Can you show me how to wire it up? I'm having trouble, I got this far but I don't know if I'm doing it right: **broken link removed**use individual swicthes for both. One swicthes the Motor, and other swicthes the Lamp. Simple.
4.5 V is not hazardous per se. 9V or 12V is better when you can replace the mains powered pump with one that works at a lower voltage. In this manner, you are keeping the mains voltage away from the water and the low voltage lighting portion of your circuit.Using 4.5V is a hazardous voltage? I have to use 4.5 because I am using a Maglite light bulb because they project the shadows on the wall the best compared to other bulbs I've tried. Why is 9V or 12V better?
It is an "AC Power Jack" and must be rated for mains voltage and the current draw of your pump and transformer combined. Connecting to it must be done with extreme caution.How? What is the little port thing called?
You diagram seems to be missing the line for the mains connection, but theoretically you are on the right track. However, once again the issue of mixing both mains and low voltage in your switches is a problem. What if there were an accidental connection from the pump switch to the 4.5v light switch? It would not be safe...Can you show me how to wire it up? I'm having trouble, I got this far but I don't know if I'm doing it right: **broken link removed**

You do not appear to be familiar with working on mains voltage. I strongly recommend you do not attempt to complete your project in this way. I urge you to find a low-voltage pump and only supply low voltage to your device. If you can find a 12V water pump, it is a simple matter to convert the 12V to 4.5V for your preferred lamp. We will be willing to assist you in this regard.
As to "What is thing thing called", it is a receptacle or jack. In the US, I would use a power cord like that found on desktop computers (called an IEC power cord) and connect it to my project with this
I live in the USto determine where you can search componnents for, letting know your location will get you better answers.
