be very careful with dimming leds. it is critical you have a driver that can handle dimming, most cheap ones can not

Thanks for the info calo247. So the total wattage I need is 20.25 and 19.5v. If I get a 24v power supply, would this be ok?
About the driver, my Current USA dimmer supports the LED strips but I'm not sure about my Fluval LED bar. How would I know if it needs a driver? I've run it (just the Fluval LED bar since it came with it's power supply) through my dimmer a few days now and seems to be working fine so far.
