Ohms Law and something worked on Seafever :)

On the same day






All this debate about amps and the accuracy of watt claims on bulbs and other items got me curious

But somehow i got a lucky break and one of the wiring items still in good shape on Seafever is the cabin lights of which there are two old style GE 1004 bulbs and the two modern fixtures above

I figure if you can go to home depot and still buy 10 or 20 watt bulbs there modern

It would have sucked if the wire there was bad because its covered in really nice wood strips held down with brass brads


BUT anyway the old school 1004 13 watt bulbs can in slightly low at .96 amps and the modern 20 watt bulbs came in at 1.65 right on the money for a pretty massive 5.2 amp draw

BUT at least it works and i can move on to soemthing else for now

Tom, if you have replaced incandescent 13w with 20w halogens you could possibly have a heat problem as the halogens will be nearly twice the heat output of the incans. Maybe no concern but you might just check the panel behind the light itself.

(We are in the process of playing around with LEDS in the cabin but I have been using 10w halogens with good result and less heat. )

No there are two original fixtures with the 12 was 1004 bulbs and two new ones with the G4 20 watt

I found the 10 watt G4 bulbs at the store and the sensabulbs will also fit at a later date when i feel like buying the 39 dollar units
