Make Lamp as power load

Posted: 17 Jun 2016 05:30 AM PDT

We like to test the functionality of a high current power supply by simple power load. It is 12V lamp 50 watts. But it had a high temperature. Require a docking station proper on long time trials. Today Chayapol build docking for this lamp. Figure 1 All parts We use: – Light bulb – Metal screw 2 inch – brass hooks as terminals – Thick wooden planks We use Incandescent motorcycle head light bulbs 12V 25W/25W without a head light socket Figure 2 The structure inside light bulb The structure inside light bulb has two filaments for the high beam and low beam filaments are soldered two parallel, it would have a combined 50 watts as Figure 3.
