I used the Cannons for a few years. Even have a brand new one sitting in the box unused. The cannons were certainly welcome when they first came out as there was not much within decent price range at that time. I can't ever recommend a one light set up no matter what the light however. The problem with the cannons was that their switches have always been somewhat fragile. When I used them, I always traveled with 3, in case a switch screwed up. Like all HID lights, they need time to power up but did not find that to be much of a problem. I liked the cannons for daytime use but also always carried halogen video lights for night time use. The reason was that with the cannons a full 6k, their light was too blue for night work. Sometimes I used 2 diffusers per light and sometimes just one, depending upon the conditions. They can have a hotspot without being properly placed. Then there was all the batteries and chargers I needed to pack and carry that the cannons demanded.
Now I use the L & M HID lights and am happy with them for both night and day. Of course, they are significantly more expensive. For an inexpensive light you might also check out Nocturnal lights whose build is much more robust than the cannons.
