I use the LX20+ as well. Primary considerations for my decision were the smaller beam angle (brighter spot, 20% more lux based on specs) and constant-current driver (stable brightness). Longer runtime on high and lower price also favor the LX20+.Why the LX20+ instead of the Dive Rite HP50?

You've not alone, but the reason is an inverse-squared dependency on spot diameter.I'm surprised by that. I know it's 10 degrees versus 6. But, it's also 3500 lumens versus 1500.
Your guess is based on diameter rather than area, which leads to a faulty conclusion. High on HP50 is as close to the same lumens per area as it can get.Why compare runtime on High instead of runtime when putting out 1500 lumens? It looked to me (my guess) that the HP50 would have a longer runtime when running at approximately the same brightness as the LX20+.
From Dive Rite:Do you happen to recall where you found info that the LX20+ stays the same brightness all the way until it goes into low power mode?
My last burn test gave 2:45 on high (stock batteries) before stepping down.A true constant current LED driver provides unparalleled efficiency and ensures constant light output as the battery is depleted.
Yeah, the spec of 2:15 vs 3 hr doesn't make sense to me either. Certainly it will go past 3 on Med, but I haven't quantified how far.I would have thought burn time at half the output would be at least double.
I think there was no HP50 when I got my LX20+ ??Just curious. Why the LX20+ instead of the Dive Rite HP50?
In a huge passageway I like it on bright, but normally I am just fine on setting #2.Your eyes are probably better than mine, I sure like my LX20+ on high!
That is great analysis (as I generally expect from you, of course). Thank you!
You hit the nail on the head on the bottom line: My shop is a dealer. I am getting it at dealer cost. It's not part of the uniform, per se, but all the shop staff except me do use them. And, enough people that I know use them for cave diving that I want to try it out.
If there was a MIA light that was good as a spot beam for caves and also switchable to a good flood for video, all in one light, and I could get it at dealer cost, I would definitely want to try it! As it is now, the only MIA video lights I know of are UWLD and the 10K lm is way out of my price range and the 5K is also out of my price range and it's not cordless (which I do want).
