LED driver questions

I know a fair amount about fluorescent and HID ballasts, but know next to nothing about LED drivers. I have an LED parking lot post light at work that has a bad driver, and I am having a VERY difficult finding a replacement. It is a 60 watt Thomas Research Products constant current dimmable LED driver, output is 1670mA, output voltage is 12-36VDC. I need to find something equivalent, but it doesn't need dimming capability. The only source I found is Digikey, and they have a 12 week lead time.
Anyone got a few minutes to school me on LED drivers, or direct me to a good source?
Thanks,
Andy

You need a 60w driver...... 1670mah...... 36v max.

You can use a MeanWell HLG-60H-36A.
It's rated for 61w ..... 1700mah..... 36v max.
Looks to have internal trimmers for fine adjustments.

Can be found on Amazon. Shop around for best price.

A LED driver is essentially an AC to DC converter. In your case the 120 vac is converted to 12-36 vdc (adjustable) at 60 watts max. If the LED driver has dimming capability, it contains circuitry that controls ( based on selection) the on/off time the LEDs are conducting to dim the light.

We constantly have problems finding replacement drivers locally. Your best bet is online as you have found.

When choosing a driver there are two types, constant current and constant voltage. Most common in fixtures will be constant current type.

The best thing to do is to match the voltage range and milliamp output as close as you can.

Thank you all. Good plan with the Meanwell unit. I'll look into this next week.
