We’ve used both extensively, and the Wicked Lights are definitely marginally brighter, and the mount is more solid. Not to say the F900 isn’t a good lamp as it certainly is.
Hi Mark, so it depends on a number of factors, environment, what your local foxes are used to (if anything etc). We generally start with red, and go to green if it’s a bit hazy out. We don’t tend to use white a lot, but it can be useful sometimes.
