U did replace my 50 watt Duckworh bulbs with 200 watt bulbs and am very happy with them.
Someday, when LED's become reasonably priced, I will replace them but for now, you can't beat $5 every five or six years.
Wow! 200w is 14amps or so. Hope you've got 10 or 12gage wire out to them. The biggest ones I've seen for the Duckworks halogen were 120w. I had the 50w then the 75w and finally the 100w halogens in our 6A and the last two were pretty good. Can't answer about the FlyLeds lights, but I am very satisfied with their strobe and position lights. Running BD squadron pros in my 6 and they are pretty bright, if a little sensitive to aiming. If I hit the lottery, I'll go to the the 9500lumen XL80s.

14 AWG is all that is required for the short wire runs in our wings. Since I'm a taildragger, each light is on its own breaker-switch; left is taxi and right is landing.
At 400 to 500 feet the threshold is bathed in light. I was very surprised and impressed.
Two 100w bulbs, one in each wing, each on a different circuit. Our wire runs are not that long and my lights are in the leading edges, not the wingtips, which helps.Maybe I misunderstood. Do you actually have 200w bulbs or 2 - 100w bulbs?
With the longer RV-9 wing and getting the wire to the panel, I figure 15' of wire, possibly more. 100w at 14v would be something over 7amps. The wire size chart from AC43.13 shows that a 14awg wire would be good for somewhere north of 20' - all good so far. 200w is 14.3amps. The 15A line on the chart crosses 15' about 3/4 of the way from 14awg to 12awg. You always round up using this chart, so if it really is 200w the wire is undersized. Probably not enough to burn up, but it will have more voltage drop and run warmer than industry standard. In an enclosed conduit with other wires, they would be warmer too.
