Light Emitting Diodes or LED’s are rapidly becoming the preferred option for fitting in applications where low current and a long life are beneficial. Obviously on a yacht where power is supplied from batteries for some or all of the time, reducing the current draw delivers a lot of benefits. Longer battery duration so longer between charges for example. The added benefit of very long lifetimes is another drawcard.
There are some pitfalls however and the consumer is not helped by the lack of a common knowledge base. This post is an attempt to throw some light ( sorry 🙂 ) on the whole subject.
1 – Led’s are polarity sensitive
2 – led’s are current driven devices …. Not voltage driven!
