My point is that you don't need a relay. Halogen off road lights are rated at 12v because they use an H1 bulb, and that's what the government uses for ratings on automotive bulbs. Where did you get 87% from?

Ok you're getting closer on the wiring issue, please refer to Karl's post for the statistic. If we are going to compare lights let's use the same standard, it doesn't matter which one but keep it consistent. Also this is not a rigid bar. Lastly if we are talking about what is needed, neither a switch, relay, or fuse is needed if you are willing to hold the wire ends onto the battery posts...
I was using the same standard for both, until you decided it would be better to use 14.5 volts until you saw that it didn't fit your argument.
Also, there's no need to hold the wires onto the battery posts. Just jam the wires into the terminal and you're set.
