We sell the Keldan and the iTorch (and others).
The
Keldan Video 4x are a true 6000 lumens and 5000k light with an accuracy of 82 CRI. Which means that the light has a truer color balance and the rated output is extremely even. The large wheel on the back makes them pretty easy to turn and adjust up and down. They are a bit larger than the iTorch, probably about he same weight in the water. You can change the light heads out for a blue or UV one. They are Austrian-made, so the build quality is better than the iTorch models, which are made in Hong Kong. Definitely a nicer light. But so is the price.
The controls on the
iTorch Venom 50 are good with 2 buttons dividing mode and output. Beam is quite good, but with a CRI of 72; so the white balance is not as good and may wander a bit. But not as easy to deal with as the Keldan. The remote control helps a lot, but keep in mind you'll need a separate control and sync cord for each light. That's going to add to their cost.
They are working on a high CRI 92 version, but it's still in prototype.
Another great light in the
Fix NEO 3000, which also has a remote and is smaller like your Solas. One remote can work 2 lights together, separately, or put them into sleep mode.
It looks like you're in the Great White North. We can arrange direct shipping on the ITorch products from within Canada which will save you duty.
