Since it takes a lot of efforts to produce energy on board the savings of LED compared to the old Light bulbs are substancial. With the energy to run 1-2 of the old incandescent today the whole boat is covered. Under a practical few I donīt see any better choice.
Was allways wondering how so many talk about quality issues with the LEDs.
Well, i can not confirm those issues as of yet and I am using ebay...so nothing special and same quality as in RV.
Anyhow I friend of mine had some problems and we investigated a little and came to the conclusion that also the quality of the energy plays a role. Using the charging
spec of the battery
manufacturer he adjusted all charging
devices. We measured the changes on the high side of the voltage with spikes between 14,5 to 15 volts, while till now we have never found out what the max. voltage tolerances for the LED really are.
After installing a stabalizing transformer for the whole LED circuit the situation has improved a lot ....not that they last for ever but since than he says he is changing may be 1 LED per year if at all, while before he had to change at least 5-8 per year on the whole RV. I think also bad contact might be a reason for problems.
To me that means also quality of the energy plays a role and it might be recomandable to inspect where LEDs burn out more than expected specially in more primitive installations for example like 2 different circuits of batteries charged by just one alternator
of the engine
As far as safety
issues I think itīs the safest light around allways if properly cooled. In higher wattage LEDs a heat sink would be a good idear specially with smaller enclosed fixtures to stabalize the temperature wich is the only other source for failure
