Our 31mm festoon warm white 3000-3300K LED bulbs incorporate 12 surface mount diodes to provide 60 lumens of light. They feature 6 diodes pointing forwards and 6 diodes pointing in opposite directions to give a wider spread of light. Ideal for use in narrowboats, caravans, campervans, caravanettes, cars and other battery driven applications. They can also be powered by a suitable Led driver which we can also provide. They work in the 10-30 Vdc range so are suitable for many applications up to 30 Vdc.
The connection pins are polarity neutral (it doesn't matter which way the positive and negative are connected as the bulb manages it) and have a surge suppressing circuit to protect the bulb from voltage overloads
Note: These bulbs may be different in size to the halogen equivalents. Please ensure you check the dimension diagram before ordering.
