My personal comment :
SOLA has smoother edges than i-Torch but as a focus light or video light, underwater its hard to tell. In air and on a wall, edges is visible.
Since most cameras are contrast focus, and if budget call to choose one, I will choose i-Torch simply because it covers the focus zone well or at least 50-70% middle zone where most focusing occurs ( yep depending on your lens ). If I got the budget, I will choose both because SOLA 800 is lighter. I have both of these lights.
SOLA 800 being a sealed system and only 60 minutes burn time is not really fun for remote areas photo diving. If surface interval is less than 2.5 hours and mother boat has to have electricity supply, it can still be a problem. If diving on small boats without charging capability, you are doomed for dive 2 , 3 & 4. With replaceable batteries, buy 3 spare batteries ( cheap ) and you are covered for whole day 4 dives diving day with no worry. The reasoning of sealed system is more waterproof is not true. I dove Underwater Kinetic D8 and opened/closed it for 100s of time without issue. We do open up our camera housing...don't we ?
I use the i-Torch Video Pro4 as primary wide angle dive light, paired to another 750 lumens 18 degrees i-torch Sub Mini as a distance thrower.
Gone are the days wasting time scanning around with UK D8 lights or bulky cannister type light to get 2,000 lumens.
I like lights and I am not an UW photo guy. I am a GoPro video guy for fun & pleasure.
Hope this helps.
PS:
Sorry, I did not do 1st time introduction. I have seen this post before I got the i-Torch Video Pro4, hoping to get some comparison too, now I can give you guys answer....
