Question: I have a power supply for DL LEDs that went toes up. Local supply house wants $85. Retired old guy markup, I’m sure but I can’t seem to find them at all online. Suggestions as to where?
Okay, let's troubleshoot this LED power supply situation. It's frustrating when local suppliers have such inflated prices! To help me give you the best advice, I need a little more information
1. Specifics of the Power Supply:
Voltage Output (VDC)
This is crucial. It will typically be 12V, 24V, or sometimes 48V DC (Direct Current). It's usually printed prominently on the label.
Wattage (Watts)
This indicates the total power the supply can deliver. It's also on the label.
Amperage (Amps)
This goes hand-in-hand with wattage. You can calculate it if you have voltage and wattage (Amps = Watts / Volts) or it will be directly printed on the label.
Input Voltage (VAC)
This is the voltage coming into the power supply, likely 120VAC, but check the label.
Is it Dimmable? If your LEDs dim, the power supply is likely dimmable. If so, what type of dimmer is it compatible with (e.g., TRIAC, 0-10V, PWM)? IP Rating
Is it a waterproof power supply? (Look for ratings like IP65, IP67, IP68)
Dimensions
Measure the length, width, and height of the power supply. This is important if you need it to fit in a specific location.
Connector Type
How are the LEDs connected to the power supply? Screw terminals, quick-connects, plugs?
Brand and Model Number
If there is a brand and model number, write that down as it will help with finding a direct replacement.
A photo of the label
A picture is worth a thousand words! Uploading a clear photo of the power supply label to a site like Imgur (and sharing the link) would be incredibly helpful.
2. What kind of "DL LEDs" are they powering? Strip lights? Puck lights? Recessed lights? Something else?
Knowing this will help determine if there are specific types of power supplies commonly used for those applications.
Where to Look Online (General Suggestions)
Amazon
A good starting point for a wide variety of LED power supplies. Use the search terms "12V power supply," "24V LED power supply," etc., and filter by wattage and amperage.
eBay
Can be a good place to find slightly used, refurbished, or discounted power supplies. Be sure to check the seller's feedback.
Digi-Key or Mouser Electronics
These are reputable electronics distributors that carry a huge selection of power supplies (often from major manufacturers like Mean Well). While they might seem more geared towards professionals, they often have the best prices and reliable specs. Use their parametric search filters to narrow down your options.
LED Supply Stores
Search online for stores that specialize in LED lighting and supplies. They often have a good selection of power supplies specifically designed for LEDs.
Home Depot or Lowe's
While you might not find the exact replacement, they may have generic LED power supplies that could work if the voltage and wattage match.
Tips for Searching
Use Specific Keywords
Don't just search for "LED power supply." Use the voltage, wattage, and any other relevant information you have.
Look for "LED Driver" or "LED Transformer"
These terms are sometimes used interchangeably with "LED power supply."
Check the Specifications Carefully
Make absolutely sure the replacement power supply meets or exceeds the voltage and wattage requirements of your LEDs. Underpowering can cause dimming or flickering, and overpowering can damage the LEDs.
Read Reviews
See what other customers have to say about the reliability and performance of the power supply.
Important Safety Considerations
Turn Off the Power
Always disconnect the power before working on any electrical components.
Match Voltage and Polarity
Ensure the voltage of the replacement power supply matches the voltage required by your LEDs. Also, pay attention to the polarity (+ and -) of the wires.
