Here's a quick DIY tip for upgrading your P21 light to a spring-loaded design using 220V copper wire. Start by getting your hands on some reliable 220V copper wire with a gauge of at least 1.5mm2, strong and capable enough to create a durable spring. This will come in handy when making the necessary adjustments to secure the bottom of your P21 light. Be cautious when working with electrical components, especially high-voltage devices like these lights which can get incredibly hot if mishandled. When modifying the light, remember to take extra precautions and work with utmost care to avoid any potential safety risks. You might find this modification useful for custom applications where a 12V source needs additional load capabilities. For instance, when creating an ATX bench power supply from scratch, having the ability to easily replace lights or other components becomes extremely helpful.
