Here is what I came up with. Any faults in this circuit? Problem with using a light bulb is in the event of a bulb failure, I no longer use enough power to trigger the TRIAC to turn off potentially. Thus the pump could continue to run and over dose my tank.
yes it is a mismatch, a mismatch I am looking to solve by increasing the wattage drawn by the dosing pumps.
All I am looking for is a 120v Circuit design that will allow me to power a LED light and a resistor that will disapate 5-10watts.
Truth, I am not sure...
But here is some more information... I purchased some aquarium dosing pumps. I also purchased an aquarium controller that uses TRIAC outlets to switch the dosing pumps off and on based on a program.
The problem is the dosing pump draws so little power that the TRIAC...
I need a led circuit that will pull between 5 and 10 watts.
I was going to put a 1.8k resistor with a diode and led... however. Not really sure if that is the right way to go.
The reason I want this is I have a low power device that doesn't pull enough power to trigger an alert. Please...
