I will try to take a picture of the different beams at some point.
I'm pretty happy with the LX20+
Did you ever take pictures of your LX20+ against your DGX 800s?
I am in the same position you were trying to decide on my first serious primary light, having used DGX 600 and 800s up to this point. They did me well for my Cave training but I am very aware I now need something brighter for a primary.
Are you still happy with your LX20+? Does it feel bulky on your hand?
Also seeing the 6' beam vs the larger 10' beans are you happy you chose the LX20+ over the HP50?
