I was just informally using flashlights with a guy with low vision because of retinal problems. He was able to see the L4 - when he could no longer see much weaker lights - like a Fenix L2T on a cr123 tube, or a Fenix L2P, or an Innova X-5, or a Civictor.
Lights that throw well may not work for my needs. I own a Streamlight tasklight 2L and it throws great. I use it to walk the dog.
I don't think that it has the same effect as the L4.
I was especially interested in how the Cree would compare with an L4.
I know that the L2 is a little brighter than the L4, but also read that it sets your hands on fire after it is on high for awhile...
Anyone know about this?
