Re: LED upgrade
Reply #22 –
There are (too) many types of these led g4 puck "bulbs". Next time I plan to buy the right type.
Many of them only contain LEDs and resistors. These are usually called 12 volt lamps. Not the best to use in a system where the alternator might send a higher voltage to the 12 volt system.
Look for LEDs that claim a voltage range, like 10 - 30 volts. These should have voltage regulator integrated circuits, and probably an inductor if they have switching regulators.
I found some where the LEDs have lenses. These are too thick to fit without removing the reflector.
The ones with 9 LEDs are often 25mm diameter, a better fit than 30mm 12 led models.
Color wise, white tends towards blue and warm white tends towards yellow-green. I slightly prefer warm white.
I find the leads difficult to insert into the socket, and much more fragile than the steel leads on halogen bulbs. They are soldered to the PC board and easy to break off.
