fish camp light bulb failure(info)
Watts is a measure of power. Current is measured in amperes.
JimL wrote: jean, I'm confused on what you're saying. 40 watts is the current limit for the bulb, period! Unless of course the voltage is too high thereby forcing more current through. From what I see of these outdoor converters, the voltage output is constant. Manufacturers just don't want you to overdrive them with more wattage of bulbs than the trancformer can put out. -JimL jean wrote: TOM make sure that your circuit is a parrallel one, not in series.Also you cannot reduce the watt of the bulb because you will reduce the resistance of your circuit and let pass to much current on the same bulb (burning action) "Tom Best" a écrit dans le message de om... I would appreciate some help with a 12 volt question. I set up a 7 light long string of 12 volt, 40 watt bulbs on a strand of 12 guage, outdoor lighting, copper wire. The bulbs and bases were standard Edison screw base types. The lights were connected to a 300 watt DC converter made for outdoor yard lights. In theory, I would like to take the same string (with lower wattage bulbs) on sailing trips. In 4 days, 6 of the seven lights have burned out. One light continues to burn at normal brightness. Any ideas or comments on these failures apprecitated. Thanks Tom |
