The factory ceiling light fixtures take six 1156 bulbs, but how many watts are each bulb? (can't find a definitive source for that info. maybe it varies?). How many "hockey pucks" would it take to replace the amount of light of one of these 6-bulb fixtures?
I'd like to someday replace my front vent with a fantasik fan, but that would mean loosing the light fixture.
I believe that the 1156 bulb is a brake light bulb if used in automotive terms. Those usually are reated at 21 to 25 watts each. Over 2A draw each, anyways. So, at 4 bulbs per fixture, you're getting 80+ watts, and a healthy 8a minimum draw. More like 100W, and 10A draw...... I know you said 6 per fixture, but mine only had 4 per fixture in the 71 Tradewind. You can do the math for 6 bulbs per fixture. Definitely not boondock friendly.
The light produced by these original Airstream lamps is yellow, and inefficient because it is diffuse, not concentrated.
A 10W halogen can definitely replace a 1156, no contest, at half the wattage. All of my 10 ceiling halogens consue about the same energy as a 4-bulb ceiling light with 1156's in it, all 4 burning.
I'd venture to say, though, that the light is much more pleasant, and less warehouse-ish.
The Halogen light is quite white, which translates into a higher light efficiency than regular bulbs.
