i want to replace my 500w halogen bulbs with Hids. Which i estimate produce 5000lumens.
My hid is 100w, but thats power consumption. Output is 75w. So at 100 lumen/watt that should make 7500 lumens.
A bit worried about the buzzing sound coming from the driver.
Also, at startup these bastards ar power hungry. Directlt connected to 16a 12v power supply i was unable to start the light. 24v 4.2A did not do much good either. But my 14.4v 7ah batt starts it nicely and runs for 30 mins.
Any ideas on that?
