Default fish camp light bulb failure(info)

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)


jean;
1) The original poster stated that he had seven (7) bulbs "in
parallel", so that's not an issue.
2) Do not understand your "reduce the watt of the bulb"
statement. It appears wrong. If you reduce the wattage LESS
current will flow (Volts x current = watts). And the resistance
will INCREASE. Basic Ohms Law!
Example: 12 volts x 1 amp = 12 watts. Resistance of lamp is
Volts/Amp = 12/1 = 12 ohms.
Example: 12 volts x 2 amps = 24 watts. Resistance of lamp is
.......12/2 = 6 ohms.
Thus: Twice the resistance results in half the wattage.
