We understand what we offer you in our store.
For all the seeming simplicity, there is practically no information in the public domain on the issue of artificial lighting. There is no sensible textbook, having studied which one could become a more or less educated person in this area. You need to study a lot of information to get at least some answers - I say this based on my own experience. Not everyone has enough desire and even more time for this.
Therefore, even among actively practicing underwater hunters, you can find the most contradictory opinions about the choice of the optimal underwater light. The main argument in these disputes is "I like it more!" But people like this kind of light, as a rule, either because they are used to it or simply have not seen anything else.
These disputes are useless - we have a different approach, we rely on more essential categories - physics and physiology. And in our opinion we are good at it!
