I just picked up a used WL X1600 and an older Ultra 600 for a song. I'm looking to round out the kit with another "X" series strobe, but I'm a little unsure what size I should go for. My gut tells me I don't generally need a lot of power and go with the X800, but the X1600 can be dialed down one extra stop and I'm wondering does that actually let me take an X1600 down to X800 or lower levels or does it perform poorly at the basement settings? Used pricing is so close to the same for both it's really a performance issue. AFIK the 800 and 1600 use the same flash bulb, so assuming the internal circuitry is similar I would expect similar performance, color temp, etc. But I'd love to hear from people that have experience with them. Thanks!
