This is why I made the switch to the new UK Aqualite Video light.They have no external battery for extended usage, and also to buy two more lights is way past the practicality of buying these lights in the first place as two came to almost 2000. means for another dive, I would need to buy two more lights. Doesnt make sense, unless your the guy selling them.
While they only put out 600 lumens at 1.3 hours they are much less expensive than the Sola lights.
The UK Aqualite Video lights are priced at $240 each and that allows me to purchase two or three for that price.
