What is an LED Flood Light?
Image showing floodlights in a soccer stadium.LED floodlights serve as ultra-bright lights that will lighten up spacious areas. Or example, you may see them commonly deployed during a nighttime sports event. Plus, these provide excellent lighting conditions during an outdoor event such as a concert or festival. Different industries, organizations, and companies may also utilize these in a light fixture to brighten up specific areas.LED floodlights come in various shapes and sizes. Nd you can utilize them for different purposes.
DIY Dimmable LED Flood LightWe introduce a practical lighting solution that will suit your needs. Use the below circuit diagram as a reference to build a floodlight.

Steps:Follow these steps to complete the project:
The first step involves disassembling the LED floodlight casing.Source: Wikimedia CommonsFirst, take the old LED flood light case and remove the LED driver. Afterward, remove the LED driver’s glue. You will need to utilize an adjustable wrench and plier to remove the wire’s waterproof seal. Next, remove the old LED by desoldering its connections and removing each screw. Ensure that you also remove the old heatsink compound and apply a fresh layer. Afterward, insert a new LED and screw it in place.
Step twoThis step involves the boost converter. First, desolder the converter’s potentiometer, which will serve as the trimmer potentiometer. So keep it nearby! Next, grab the 10K potentiometer and solder one 10K resistor to the central pin. Afterward, solder a wire to that resistor and another wire to the potentiometer’s left hook.Next, solder the second 10K resistor to the other potentiometer’s middle pin. Apply a heat shrink tube to the connections. Then, connect a wire to the small potentiometer’s resistor and a second wire to the plug underneath the gold knob. Finally, solder these wires to the contact points where you removed the old potentiometer from the boost converter.
Adjust the LLED’sforward voltage with a voltmeter.Next, ensure that you set the LLED’sforward voltage appropriately. T should not exceed 30 Volts. Next, ensure that you set the LED’s forward voltage appropriately. It should not exceed 30 Volts. Otherwise, the LED will no longer operate due to burnout. To do this, connect 12V to the boost converter’s input and attach the voltmeter to its output. Afterward, adjust the dimmer potentiometer to the maximum setting. In this case, rotate it to the right. Next, turn the trimmer potentiometer counter-clockwise until the voltmeter displays 30 volts. Lastly, rotate the dimmer potentiometer to change the boost converter’s output voltage. It should have a maximum rating of 30 volts, which helps maintain the LED’s voltage range.
