driver for led lights

stevesleds.com has some that should work for you. Any on that site should be sufficient. Just find the ones that closely match the original power specs. You also want to be sure you get a variable voltage/non-variable amperage driver. That just means the driver will change its voltage to supply the needed wattage instead of the amperage.

Mac, From those specs the units look like the majority of the Tao Tronics units around. Those drivers use a PWM dimmer to control them. If you look inside the unit you will see a small circuit board connected to each driver. The dimmer knob is generally attached to this board. There are two wires running from that board to each of the drivers. Those are your dimming control wires. I have clipped those wires and connected them to an external connector that I then run to a controller that uses PWM dimming (Reef Angel and most of the LED controllers on RapidLED and StevesLED sites). You can also get Analog to PWM adapter boards that will allow you to use an analog controller to dim them.

I found it very hard to get a compatible replacement driver for those units because of the high voltage and low constant current output. Most drivers output 700mA or 1000mA not 500mA. Some are adjustable and can be turned down to that but then don't supply enough voltage (Max of 48 to 52 Volts not 100v). I found it was easier to just use the stock driver and replace the dimming control.

Hope that helps. Krazie
