I'm looking for the simplest/cheapest (but safe!) way to build a 4.5A test-load for an LMR14050-based 24Vdc to 12Vdc/5A step-down voltage regulator circuit.
Edit (30.7.18): I commented on the responses below, but it seems my follow-up questions may be rather hidden in all the text, so I figured I'd enter them here to:
As it's a bit hard for me to find the suggested bulbs, I thought of hooking-up 9 of these alternative 5W bulbs from eBay in series to give me more or less the power draw I'm after - Would these bulbs work for the intended purpose?
Also, what would be the recommended capacitor value for each bulb?
So apparently the bulbs I found aren't suitable - does anyone know where I can order the correct bulbs (i.e. each drawing 500mA more or less at 12Vdc) online?
