I have a 12 v dc power supply 36 watt 3 amp attempting to run 5 12v dc 4 watt led lights in parallel. at first i tried running 5 hallogen lights but figured they were drawing to much power so switched them out to the leds. my question is i am being told i need to put in a resistor to keep from blowing my power supply. i do not know the led parameters such as voltage drop or how much power will flow through the led. and need to know what size resistor needed?
my led are GY6.35 G6.35 Bi-pin Base LED Bulb 4Watt AC DC 12V Silica Gel Crystal Daylight White 6000k Landscape Lighting,JC Type, Equivalent 25W- 30W Q35/CL/T4 Halogen
please note i am creating a circuit from scratch every time i try power up my lights my power supply kicks off
