Our 37mm festoon warm white 3000-3300K LED bulbs incorporate 9 surface mount diodes (SMD's) to provide 120 lumens 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 points/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.
