In Dubai you are pretty much lost, if you search for a professional photo store. To my knowledge only two stores would even sell you a 1D-X, one being in the Dubai Mall, the other being at Dubai Airport. I seriously doubt that you will get Bowens or other professional lighting equipment at these places.
This information might be somewhat outdated as I have not been in Dubai for some time. Prices for photographic equipment in the Middle East are ridiculously expensive. You would be better off to bring in the gear, purchasing it elsewhere.
