When choosing a dive light with specific LED emitters, you may need to consider what you plan to use that light for. For example, some testers and customers told they like to use the D26 1600S for cave/wreck diving. As this light uses OSRAM CSLPM1.TG LED, it can produce significantly tight spot beam (as the photos show below), characterized by good penetration, far throw, suitable for tech diving, signaling in murky or green water.

To evaluate dive lights’ emitters, there are some essential attributes, such as output, runtime, throw, color rendering... We all want to cover all the bases, high output, great tints, high CRI. In fact, this is very hard to achieve. Some emitters can give parts of what we need, but not all of it. For uw photographers, choosing the light emitters with high color rendition is much important. As for tech diving instructors, they may prefer lights emitting tight and far beam, good for signaling. How about your preference on dive lights’ LEDs, and why? Comment freely!

I like a bright, tight beam. I'm not a photographer so I choose a light that cuts through the less than ideal viz situations I often encounter. Recently purchased 5 of the d26 2500 shorts, for my wife and I, and we're very pleased with the performance. They survived a dive to 110 ffw @ 42°F, staying bone dry and performing great.
