wow, you have collected a lot of flash lights, these are great lights. But now I don't see anyone using these lights anymore because everyone is using smart phone flash lights. The lights you are using can help you focus on distant objects, everyone should have at least one of these. Good collection
Yes, the smartphone light has it's uses as well, although certainly much more limited given the comparatively tiny amount of light they give out. Even that little keychain light is like 20 times stronger. I'll still get around to doing some comparison shots one of these days.
